cristin dorgelo:hi, this is cristin dorgelo. and we're here live from thethird white house science fair. this is our first live webcastfrom the science fair. and today we're celebrating over100 students who are winners from 40 states and 45different science, technology, engineering, and mathscience competitions. and i'm here right now withbill nye the science guy, and levar burton. welcome, guys.

what are you excitedabout for today? levar burton:science. bill nye:science. levar burton:i want to see the science thatthese kids are working on. bill nye:they got some cool stuff. i was walking aroundjust a few minutes ago. this is the future! and what i like to remindeverybody is the economic benefit of science.

what is everybody talking about? what are we obsessed with? three things. cristin dorgelo:jobs and economy. bill nye:jobs, jobs, jobs! that's right. so if you want jobs,you got to have science. you got to invest in science. and these people are going to bethe engineers of tomorrow that

will, dare i say it,change the world. cristin dorgelo:thanks, bill. levar, what are youexcited about for today? levar burton:well, i think it'sremarkable, number one, that the president is reallyhonoring these student scholars very much the same way he wouldif you were an ncaa sports championship team. coming to the white house andgetting an opportunity to get some face time with thepresident is really big

for these kids. i think that's great. cristin dorgelo:so do you think we shouldmeet one of these kids? levar burton:i would love to. cristin dorgelo:all right. so we've got sarah here. sarah, welcome. sarah volz:thank you so much. i'm so excited to be here.

cristin dorgelo:so tell us about your project. sarah volz:my work is on algae biofuels. so the idea with algae biofuelsis that algae actually produce these oils that can be convertedinto a field you can put straight into you diesel engine. so right now, the problem withbioenergy is that it's not quite economically feasible. and we need a better sourceof these oils than crops like soy beans.

so that's where algae comes in. and my work was focused on usingguided evolution to develop populations ofalgae with more oil. so it's a better choice. bill nye:these are the same organismsthat make swamp gas, right? sarah volz:yep, yep. bill nye:so instead of one carbon,you get a whole -- somehow. sarah volz:exactly, yeah. so the idea is that,you know, they're just

producing these fats. that's exactly whatthey are, these fats, these long carbon chains. and if you can just get them tochange their metabolism a little bit, they'll producemore of them. bill nye:how did you do that? sarah volz:so i actually took a sort ofdifferent approach than some other people have been taking inthat i let mother nature do all the work for me.

i used a chemical thatkilled cells with the low oil production. that forced cells to adaptto produce more oils, higher oil production. bill nye:what chemical kills cells thatdon't produce a lot of oil? sarah volz:it's actually an herbicide thati chose because it specifically targets an enzyme in theoil production pathway. levar burton:now, sarah, i understandyou have kind of an unorthodox laboratory.

sarah volz:i do. so my laboratory isactually under my bed. (laughter) bill nye:your bed somehow, yeah. sarah volz:so i've got a loft bed andthen i've got a bunch of flasks underneath it. cristin dorgelo:how did your parentsfeel about that? levar burton:exactly. sarah volz:they're happy that i movedeverything out of the kitchen.

bill nye:i'll tell you what elsethey're happy about. i saw you in science news. you got $100,000 scholarship. is that right? sarah volz:that's right. cristin dorgelo:where are you going to go? sarah volz:i'm going to mit. bill nye:that's back east. i hear that's a good school.

sarah volz:i'm very excited to go to mit. levar burton:they're lucky tohave you, sarah. they're lucky to have you. cristin dorgelo:are you excited to be hereat the white house today? what are you lookingforward to most? sarah volz:i'm so excited to be here. i'm really excited to meet thepresident again actually because i saw him one time before. i think just seeing all theother young scientists from

across the nationis just like really, really awesome and inspiring tosee that other people beside me care about this stuff. levar burton:what grade are you in, sarah? sarah volz:i'm a senior. levar burton:a senior, on your way to mit. good for you. well, thank you. for those of you just joining,we're here at the third white

house science fair, and we'redoing our first live webcast. sarah, congratulations ongetting to this point. awesome. levar burton:congratulations, sarah. bill nye:cool. way to go. next up we haveeaston lachapelle. how are you? nice to meet you.

easton lachapelle:great. thank you. levar burton:easton, how are you? good to see you. you're from colorado? easton lachapelle:i am. levar burton:indeed. what's your project? easton lachapelle:i created this roboticarm that's controlled

using your brain. my end all goal for this is tocreate an affordable prosthetic for everyday use for reallyanybody that needs it. and actually, the main thingthat really got me toward prosthetics was last year,at the state science fair in colorado, this seven year oldgirl came up to me and she had a prosthetic limb from the elbowto the fingertip with one motion open, close, and one sensor. i started talking to herparents some more about this,

and just that alone was $80,000which is a lot of money. and she was seven at the time. so she would need about twoor three of those within her lifetime becauseshe keeps growing. and that was kind ofthe a ha moment for me. i already started working withrobotic hands, robotic arms. and i just crossed platformsperfectly with that. my end all goal is to createan affordable prosthetic for everyday use.

and it's all controlledwith your brain, based off thoughts and alsofacial gestures and blinking, a series of patterns. and also a musclesensor on the foot. combine all that together,and you get a really accurate control system thatyou can really use to control everything. levar burton:so how many movementsdoes your arm have? open and close, butmore bells and whistles?

easton lachapelle:it's a full roboticarm up to the shoulder. and it's comparable to humanstrength-wise, weight-wise, and functionality. so pretty close to thesame degrees of freedom. but during all this, i reallyrealized how remarkable a human arm is and just how crazyeverything happens. bill nye:how complicated it is. easton lachapelle:yeah, yeah. bill nye:and the sensors, it's amazing.

so what powers this thing? easton lachapelle:i actually use servomotors asthe main actuator for each of the fingers. bill nye:but upstream, wasthere a battery? easton lachapelle:yeah. that's all within a bicep. all electronics, all thebatteries are within a bicep. and i have about a 5,000milliamp-hour battery within a bicep.

and that could power thearm for a good, you know, half day to a day of continuoususe from all the motors. bill nye:five thousand milliamp hoursin the bicep is what you got. cristin dorgelo:amazing. did you have a 3-dprinter before this? was this your first3-d printing project? easton lachapelle:no. i actually have two 3-dprinters in my room. i work out of my room.

i pretty much have a bed inthe corner and i could start to expand. but 3-d printer isreally, really cool. it's a really cool technologythat's starting to get really big. and it's starting toget more affordable. bill nye:so is the final product plastic? easton lachapelle:it's all made of abs plastic. but that's like thebest way, i think.

either way, you have some typeof exoskeleton or some type kind of skeleton that puts thesilicone skin around. and it's just a light weight. it's durable. it's easy to replace. it's affordable. so yeah, i thinkit's a good choice. cristin dorgelo:well, thank you, easton. what are you excited abouthere at the white house today?

easton lachapelle:well, this is actually thefurthest east i've been. so just even beinghere is an experience, let alone the white house andall sorts of different things. and of course, meetingthese crazy awesome people. levar burton:what are your plansfor college, easton? easton lachapelle:well, my business is actuallyreally taking off with all this. it's kind of somethingi never really planned. but definitely collegeis in the future. i'm a junior right now, so ithink i need to start thinking.

levar burton:venture capitalists knockingon your door already? easton lachapelle:actually, yeah. levar burton:congratulations! congratulations. cristin dorgelo:well, easton, thankyou very much. bill nye:that's cool. way to go! cristin dorgelo:so for those ofyou just joining, we're here at the thirdwhite house science fair.

i'm here with levar burtonand bill nye the science guy. levar burton:and it's earth day. it's earth day, y'all! bill nye:earth day! cristin dorgelo:it is earth day. in fact, behind us right nowwe've got a lot of earth science projects and environmentalscience projects that are going to be really cool for thepresident to check out in a little bit.

we're ready to meet ournext student, jack andraka. amazingly inspirational story. jack, i'm cristin. great to meet you. bill nye:jack, hi. levar burton:morning, jack. bill nye:saw your picture in space news. jack andraka:so essentially what i've createdis a three-step method to attack pancreatic cancer, ovariancancer and lung cancer that

takes five minutes. it's 100% accurate so far. but also, you can detect thecancers in earliest stages, when someone has close to100% chance of survival. so it could lift the pancreaticcancer survival rate from 5.5% to close to 100%. and it could be broadly appliedto really any disease ranging from alzheimer's to heartdisease, other forms of cancer, including hiv/aids.

bill nye:how does it work? jack andraka:so essentially what you have isthese long thin pipes of carbon, carbon nanotubes. and they're an atom thick andone fifteen thousandths a diameter of your hair. however, despite theirsize, they have these incredible properties. they're kind of like thesuperheroes of material science. so then i was actually sittingin biology class reading about

these and there are thesethings called antibodies, essentially molecules that onlyreact with one specific protein, in this case, acancer biomarker. and what you do is you kind ofweave them into this network of carbon nanotubes such that youhave a network that only reacts with one protein. but also, it will change itselectrical properties based on the mal proteinpresent, in other words, a way to attackpancreatic cancer.

and i just measured that withan old (inaudible) and some sewing needles. cristin dorgelo:so jack, what was yourinspiration for doing this work? jack andraka:i actually became interestedin pancreatic cancer because a close family friend died of it. and then what i realized is that85% of all pancreatic cancers are diagnosed late, when thepatient has less than a 2% chance of survival. levar burton:has an incredibly high mortalityrate, pancreatic cancer.

jack andraka:yeah. it's the cancer withthe worse prognosis. levar burton:that's right. bill nye:my uncle. so you have nanotubes. you know, i met rick smalley,one of the guys who got the nobel prize for that. how do you configure nanotubesto detect a specific protein? jack andraka:it's actually about as simple asmaking chocolate chip cookies.

you start with some water. you pour in the antibody. then you pour in the nanotube. then you sonicate it. bill nye:you sonicate it. levar burton:sonicate it! that was the step i was missing. jack andraka:and then you just takesome paper, dip it -- bill nye:what's sonicating?

cristin dorgelo:is that like bakingbut different? jack andraka:yeah, it's pretty much. and you just shake it really,really loudly or really -- levar burton:vigorously. bill nye:ultrasonic. jack andraka:yeah, ultrasonic. levar burton:ultrasonic shaking. bill nye:and what makes it -- and so theyline up with the antibodies? jack andraka:they don't actuallyhave to line up.

it's just a random orientation. i'm just disbursing themthroughout the solution. bill nye:so you have antibodiesattached to nanotubes. jack andraka:they don't have to attach. they just kind of lay on them. levar burton:they just have to bein the environment. jack andraka:yeah, um-hum. bill nye:and then when the pancreaticcancer marker shows up, what happens?

jack andraka:then the protein essentially goes into this network and it slams -- bill nye:so then it changes its connectivity because they're nanotubes. jack andraka:yeah, yeah, yeah. bill nye:that's cool, man. that is cool. cristin dorgelo:i think you just blew billnye the science guy's mind. pretty awesome.

so what are you excited forhere today at the white house? jack andraka:i'm really excited to talk withall the other young researchers because i really loveworking with other people. and right now, i'm actuallyworking on the $10 million tricorder x prize. levar burton:are you really? jack andraka:and so i'm gathering a team. so looking for somenew candidates for it. cristin dorgelo:that's fantastic.

if you guys want tojoin jack's team, i think he just putout an open call. all right. well, thank you, jack. it's great to meet you. levar burton:jack andraka, wow! brainiac on the loose. bill nye:nicely done, man. jack andraka:thank you.

cristin dorgelo:good to meet you, jack. jack andraka:you too. cristin dorgelo:all right, everybody. we're back at the thirdwhite house science fair. one of the things that we'llbe announcing today are new commitments to the president'seducate to innovate campaign which is trying to inspire morekids to get involved with stem; science, technology,engineering and math education. so what do you guys thinkthe future of stem is?

how do we get more kids likethese excited about science? bill nye:well, this event is fantastic. celebrating, just aslevar said earlier, just as you would have the worldseries winner here or the final four winner here, youhave these people here. levar burton:we are to grow thistalent from the inside. it has to be homegrown talent. if we are to really make goodon the promise to educate our nation's children and provide aneducated workforce that's going

to solve theproblems of tomorrow, we have to begin atthese lower levels. cristin dorgelo:well, that's great. so let's meet some of ouryoungest students here. hi, guys. students:good. levar burton:gentlemen, gentlemen,good morning! bill nye:some more vision, yes! cristin dorgelo:tell us your names.

what are your names? evan jackson:evan jackson. cristin dorgelo:evan. caleb robinson:caleb robinson. cristin dorgelo:hey, caleb. alex jackson:alex jackson. cristin dorgelo:and alex jackson. wow. what did you guys doto get here today?

levar burton:what's your project? students:cool pads. cristin dorgelo:cool pads. is that something you wear? student:yes. cristin dorgelo:and where do you wear it? students:in football. evan jackson:and you can use it in militaryand a firefighter and a police. bill nye:what does it cool off?

levar burton:is it a cool pad thatyou put in a helmet. evan jackson:in the shoulder pads. cristin dorgelo:like in your protectiveshoulder pads? caleb robinson:yeah. and it has gatorade attachedto it that the players can drink out of. cristin dorgelo:so it's basically aboutkeeping them cool and hydrated? why did you guys comeup with that project? evan jackson:to keep athletes fromoverheating and dying.

bill nye:did you know somebodythat overheated? cristin dorgelo:you did? while you were runningaround just playing sports? evan jackson:when i was in my footballgame, i overheated. levar burton:you overheated. cristin dorgelo:so what are you guys mostexcited for today at the science fair? caleb robinson:to see barack obama. cristin dorgelo:oh, you're looking forwardto seeing the president.

bill nye:he may get a chance to shakehands with him if he plays his cards right. levar burton:i would be shocked ifthat didn't happen. cristin dorgelo:so how hard was itto build cool pads? evan jackson:it was medium. levar burton:medium hard? not really hard? what was the biggest challenge? what was the biggest challengeyou had to making this project a

successful one? evan jackson:keeping the parts onour sample together. levar burton:keeping the samples together. bill nye:the prototype? yeah. so you did thiswith exploravision? students:yes, sir. cristin dorgelo:pretty cool. well, i hope you guys havefun at the science fair.

you guys got anymorequestions for these kids? levar burton:can i get one? bill nye:yeah. evan jackson:yes, sir. levar burton:how soon will it bein on the market? do you know? students:in 20 years. levar burton:twenty years. so i have to wait a while.

evan jackson:or less. levar burton:or less. that's a good answer. twenty years or less. cristin dorgelo:well, it's greatto meet you guys. congratulations on being here. bill nye:nicely done. levar burton:congratulations, fellas. well done.

bill nye:great to see you guys. the idea is in exploravision,you come up with an invention that you think will come intoexistence in the next 20 years. levar burton:oh, i see. cristin dorgelo:that's awesome. bill nye:it's part of the overalleffort for science, technology, engineering, and math. it's great. cristin dorgelo:well, thanks guys.

bill nye:you guys look pretty sharp. cristin dorgelo:it's great to meet you. take care. so here at the thirdwhite house science fair. levar burton, bill nye thescience guy and are talking to some really amazing winnersof science, technology, engineering, andmath competitions. we're also talking aboutways to get more students interested in stem.

one of those commitments we'reannouncing today is around us2020 which is a project to getmore mentors helping kids in the stem field. so tech companieslike sandisk, cisco, cognizant have made commitmentsto get 20% of their workforce devoting 20 hours to helpingkids get interested in stem. so thanks to those companies forstepping up and helping kids get so right now -- hi. i see a hurt leg.

and nice to see you. brittany wenger:nice to see you. cristin dorgelo:how are you, brittany? brittany wenger:i'm good. cristin dorgelo:so what's your project? brittany wenger:so what i did is i created anartificial neural network which is a type of program thatactually models the brain's neurons at interconnections. so it can detect patterns thatare far complex for humans

to detect. now, i applied this to breastcancer because breast cancer inflicts one in eight women. these statisticsare just startling. and, when you know somebodywho has the disease, they're even more personal. so using my program, thefine-needle aspirate, which is the leastinvasive test, the cheapest and thequickest test becomes really

accurate as well. so my program is 99% sensitiveto malignancy which is huge. and then i deployed it to thecloud because the cloud is just this incredible elastic entitythat can scale the support usage by every hospital in the world. and in the future, i'm provingthat the same tactics can also work with leukemia diagnosticsand perhaps provide insight on what proteins canbe drug targeted. bill nye:so what is this most reliabletest for breast cancer?

fine needle? brittany wenger:well, the fine-needle aspirateis actually so inconclusive that a lot of doctorsrefuse to use them. bill nye:yeah, yeah. brittany wenger:so the purpose of my project isto really revive the fine-needle aspirate so that they can beused again and so they can be accurate. bill nye:so you just talk a few cells? brittany wenger:yeah.

it causes the patient aboutthe level of discomfort of a blood test. a few cells are extracted,looked at under a microscope. and then traditionally a doctorwould say whether they thought those cells werecancerous or not. but using my program, differentattributes are analyzed so that subtle patternscan be picked up. levar burton:have you had any response fromthe breast cancer community? so it's been really exciting.

i won the google science fair,and since then everybody's been really supportive. i got to speak atbreastcancer.org. levar burton:wow. and lincoln medical center hasprovided me with more samples. and i'm also working with aninstitute in italy to test my program's capabilitiesagainst 400 samples. levar burton:are you a senior? brittany wenger:i am.

levar burton:and where are yougoing to college? brittany wenger:i actually just made thisdecision two days ago. so i'm going to duke university. i'm going to be partof the a.b. program. cristin dorgelo:whoo! so exciting. i got a full scholarshipin research funding. bill nye:i'm shocked. boy, didn't see that one coming.

brittany wenger:and i'm very excited about that. levar burton:good for you. brittany wenger:thank you so much. bill nye:my grandfather taught at duke. brittany wenger:really? that's very cool. cristin dorgelo:so i've seen you here beforeon the white house campus. what brought you here last time? brittany wenger:so i was also part of sciencetalent search which is a program

that is based on yourscience potential as well as your research. so that was a lot of fun. it was an absolutely surrealexperience to meet a bunch of other kids who are alsointo science like i am. cristin dorgelo:and post college, whatare you going to do? brittany wenger:so i want to be apediatric oncologist, but probably an m.d., ph.d. sortof situation because i want to do research and primary care.

levar burton:you know what, young lady. you better get a goodpair of sunglasses. your future is so bright, you'regoing to have to wear shades. levar burton:congratulations. bill nye:change the world. nicely done. cristin dorgelo:thanks, brittany. great work. good to see you again.

brittany wenger:thank you. cristin dorgelo:so what do you guysthink about this? bill nye:so traditionally the doctorwould look at it under a microscope, or askilled technician, and looking for the pattern. but she's got it automated. it's brilliant! cristin dorgelo:it is science. cristin dorgelo:the miracle of science.

are you guys ready to meet yetanother inspirational scientist? levar burton:absolutely. bill nye:bring it on. cristin dorgelo:hi, jonah, nice to see you. i'm cristin. jonah kohn:i'm jonah. cristin dorgelo:levar and bill nyethe science guy. levar burton:good morning, jonah. jonah kohn:i'm good.

jonah kohn:so my project uses tactile soundto improve the experience of music for peoplewith hearing loss. cristin dorgelo:what's tactile sound? levar burton:describe tactile sound. jonah kohn:tactile sound is sound throughvibrations that are in contact with your body. levar burton:right. cristin dorgelo:so are we going toget a demo later? jonah kohn:sure, if you want to, althoughit does not work for people with

normal range hearing becauseof something actually pretty interesting. you're already hearing the samefrequencies through your ears. so your brain kind of discardsthe tactile information. levar burton:interesting. but it is absolutely detectableby someone who does not have that range of hearing already? jonah kohn:yes. at one instance, i hadone of my subjects,

they were able to humthe melody of a song. bill nye:even though they can't hear it. jonah kohn:even though they can't hear. just through the tactile device. bill nye:so then people who are deafcould learn to speak without that accent, or whatever thatexpression is, that affect? jonah kohn:i think so. i'm not sure. i'm not sure exactly how muchbetter they are hearing.

but i know that my targetgroup, from the experiment, which were cochlear implantusers under the age of 55, they had animprovement of 93.5%. that's 5 out of 10 to a 9.675out of ten on the 1 to 10 quality scale i gave them. levar burton:is that both speechand music recognition? jonah kohn:no. my project was only about music. i'm looking into speech asone of my future ventures.

but this experiment was aboutmusic because many people with hearing loss are alreadyable to communicate. the ones with cochlearimplants can talk fairly well. the ones with hearing aids canalso interpret and read speech through lips and hear it. but music, because it is somany frequencies and so many different ranges and everythingin music and a lot of things going on at once, many peoplewith hearing loss can't really experience musicthe way that we can.

so i tried to improve that. cristin dorgelo:so who have you pilotedthis technology with? jonah kohn:i had 14 subjects. twelve of them had hearing loss. there were six with cochlearimplants and six with hearing aids. cristin dorgelo:what did they think? bill nye:has a manufacturer contactedyou or a medical -- jonah kohn:not yet.

i do have it for afiled patent though. cristin dorgelo:what's next for youafter this project? jonah kohn:i really, really want to lookat the neuroscience of this, see what tactile soundactually does in the brain. bill nye:so you want somebody to getan mri while they're listening? do you use your hand? jonah kohn:well, the contact points that iused were the hand, the sternum, and the back of the neck. bill nye:why did you pick those?

jonah kohn:they were shown to be extremelyconductive in previous tactile sound research. and they also are some of theplaces that wouldn't cause bone conduction. now, bone conduction issomething kind of similar to tactile sound, but it's reallyjust vibrations going through your skull, moving your eardrumsto the same frequencies that you would be hearing the music. bill nye:like when a dentist is drilling.

jonah kohn:exactly. that would be bone conduction. cristin dorgelo:none of us like thatfeeling or that sensation. levar burton:making the world a betterplace through science. you rock. cristin dorgelo:congrats, jonah. great to see you here. bill nye:see you again in a few minutes. very cool.

we're here at the thirdwhite house science fair. bill nye:reminds you of how littleyou've accomplished. cristin dorgelo:really mind blowingstudents, aren't they? so we're going to keepcelebrating these students. next up, super-awesome sylvia. hey, sylvia, good to see you. sylvia todd:hello. levar burton:super-awesomesylvia, good morning. sylvia todd:good morning.

cristin dorgelo:tell us about your project. sylvia todd:well, i have thewatercolorbot. it's a robot that paintswith water colors. it's really neat. levar burton:i saw a demonstration of thisjust the other day and it's pretty spectacular. how do you program it? sylvia todd:my dad did most ofthe programming. we have a raspberry pi whichhas a wi-fi dongel on it.

so the wi-fi isconnected to the ebb. and the ebb -- bill nye:the ebb is what? sylvia todd:eyebot board. it controls the servomotors andthe stepper motors which move the metal rods andthe stringer rods. bill nye:xy thing. sylvia todd:yeah. it sends xy coordinatesto go to different points.

cristin dorgelo:so are you giving a demo ofthis painting at the white house science fair today? sylvia todd:yes. i'm probably going to have itso, when you doodle on the ipad, then it's going tododdle on to the paper. levar burton:little match move there. cristin dorgelo:so what's the coolerproject you've seen here, other than yours so far? sylvia todd:i have walkedaround a little bit.

i saw the international spacestation thing where they grab the thing and they put it up. that was pretty cool. cristin dorgelo:the space elevator,i love that project. sylvia todd:that was really cool. cristin dorgelo:are you going to jointheir team next year? sylvia todd:i'm not really sure. they were really cool. bill nye:so on your xy --what do we call it?

sylvia todd:watercolorbot. bill nye:watercolorbot. you can magnifyor shrink, right. sylvia todd:yeah, sure. bill nye:like a pentagraph,you know what i mean? you can write real small, andit will come out real big, and so on. bill nye:that's very cool. cristin dorgelo:so sylvia, you consideryourself a maker.

sylvia todd:right. cristin dorgelo:so what are makers and howdo we get more of them? sylvia todd:well, makers are peoplewho like tinkering. they have their own hobbies. they like doing their own stuff. just to be a maker, you reallyget out there and just do something, like actuallyput something together and, you know, have fun. levar burton:what are the applicationsfor your robot?

sylvia todd:what do you mean? levar burton:i mean, how might we use itin say a commercial sense? or would it bedeveloped as a toy? or would it have amore practical use in the marketplace? sylvia todd:well, i was just thinking it'savailable for kids to program, engineer, and learnhow to use robotics. we hope for it to be akit later on in late may. i just like really want toinspire kids out there to just

make something. levar burton:so what you've createdis a teaching cool. sylvia todd:yeah, practically. levar burton:yeah. cristin dorgelo:so what are you going tobuild next after this device? sylvia todd:not really sure. we're pretty busy. but i hope to kind of hack myrc helicopter and have some fun with it.

cristin dorgelo:a hacked rc helicopter. that sounds fun. will you send us avideo when we do it? sylvia todd:maybe. cristin dorgelo:maybe. i hope to see it. bill nye:the helicopter will be takinga video of you and transmitting it to you. that's cool.

this is great. great! cristin dorgelo:so makers like sylvia are goingto get some new opportunities to play and make at new makerspaces that the maker education initiative is helping to set up. that's one of the commitments tostem and our educate to innovate initiative we'regoing to see today. so who's our nextstudent we get to meet? hi.

shaquiesha davis:shaquiesha. cristin dorgelo:shaquiesha, good to meet you. levar burton:shaquiesha, good morning. you're from chicago. shaquiesha davis:yes. represent. shaquiesha davis:i have developed anapp called baby b 4 me. it's a mobile application thatconnects parents and care providers outsideeach other's presence.

levar burton:wow! bill nye:so what, does it have a camera? what does it do? shaquiesha davis:it has a real-time chartupdate, a support net list, video, and text. the chart is where the parentgoes in and put information such as take a nap and at what timethey want their child to do this activity. and the care provider marksoff when the activity is done.

and the parent can checkthe chart at any time. bill nye:all from my phone. cristin dorgelo:so how long haveyou been coding? shaquiesha davis:i have been coding since myfreshmen year of high school, so about 14. cristin dorgelo:how did you get interested? shaquiesha davis:my school actually,chicago tech academy, they teach us coding fromthe first day we walk in through the door.

levar burton:the chicago tech academy. levar burton:where is that? shaquiesha davis:it's on the southwestside of chicago. levar burton:on the southwest side. shaquiesha davis:it's a fairly new school. this is its fourth year,first graduating class. levar burton:you're in the firstgraduating class? shaquiesha davis:no. levar burton:no?

shaquiesha davis:i'm only a junior. one more year before youinherit the senior status. bill nye:pretty cool. so what language do you code in? shaquiesha davis:i code in objective c. but i've also used acml,c-sharp, css, javascript. bill nye:so what do want to doif you go to college? computer science? is that your thing?

shaquiesha davis:it's not my first, but i would. bill nye:what's your first? levar burton:what's your first love? shaquiesha davis:my first love is nursing. i just love children, whichis the idea behind the app. but i would like to get aminor in computer programming. levar burton:i have no doubt thatthat is in your future. cristin dorgelo:definitely. what inspired you to buildthis app in the first place?

shaquiesha davis:well, the first timei baby sat my nephew, his mom left so fast thatshe didn't leave a note. and i knew that hewas on a schedule. i just didn't knowwhat the schedule was. so she came back to pick him upand she asked what time did he take his nap, which iswhy i keep saying nap. and when i told her, she justwas so frustrated because he was going to be up all night. so i realized that -- i knew that i wasn't the only person

being faced with this problem. so i just decided to make an appfor it and solve the problem. bill nye:how many lines ofcode in this app? a hundred, a thousand,20,000, 50,000? shaquiesha davis:between 100 and a thousand. it just depends on what typeof thing you want to do. cristin dorgelo:so how do you think we get moregirls interested in coding? shaquiesha davis:well, at my school, wehave a 50/50 ratio between boys and girls.

and i believe that all the girlsat my school are interested at coding. so just come tochicago tech academy. levar burton:come to chicago tech. cristin dorgelo:go to a good school. i like that answer. so thank you. what are you looking forwardto at white house science fair today?

shaquiesha davis:i'm looking forward tonetworking with other students that have an interest in meand presenting my business to the president. levar burton:shaquiesha, congratulations. bill nye:that's just cool. way to go, shaquiesha. levar burton:amazing! we're still here at the thirdwhite house science fair, first time we've been livefrom the science fair.

what do you guys thinkso far of these projects? levar burton:i'm blown away, igot to tell you. bill nye:i wanted my nephewto take a nap, so i wrote a thousandlines of computer code. okay. yeah, of course you did. it's just cool! it's fantastic! levar burton:i am not an engineer.

i play one on tv. i barely understand what most ofthese kids are talking about. very impressive. cristin dorgelo:so the president is going toget a chance to look at the 30 exhibits that are here today. and i know he will also be blownaway and is very committed to seeing more students pursuingstem through our educate to innovate initiative. what do you guys think we can doto spread the word about these

types of program that are outthere and get more kids involved in these types of stem programs? bill nye:well, this is exactlywhat we should be doing, having events like this,celebrating it so that people want to be involvedor want to try it. levar burton:so if you're out there andyou have a mind for science, get busy. there will be anotherone of these next year. you could be here at the whitehouse showing off your project

to the executive branch. cristin dorgelo:and we hope that you continueto spread the word about the science fair today using thehashtag whitehousesciencefair. spread the word. how are you guys doing? levar burton:good morning. bill nye:good morning. cristin dorgelo:i'm cristin. julie xu:julie.

cristin dorgelo:julie. spencer ottarson:spencer. cristin dorgelo:spencer. levar burton:where are you all from? julie xu:michigan. williamston, michigan. levar burton:williamstown, michigan. julie xu:yeah. spencer ottarson:well, we've createdthe orca system.

it's a buoy that is designedto detect rip currents in the great lakes. cristin dorgelo:so are you demonstratingit in a tank today? julie xu:no. we didn't get tobring our tank today. but we have tested our actualflow meter and everything. so we know thatthat is operational. cristin dorgelo:and have you deployedit in the lake? spencer ottarson:no.

we have not deployedit in the lake yet. it's still a work in process. at this point, the only thingthat's been in the water is the flow meter. levar burton:what's the value and thebenefit of the technology that you've invented? spencer ottarson:well, last year, over 100 peopledrowned in the great lakes. and almost a third of thosewere due to rip currents. levar burton:really.

and so our invention is designedto help save those lives. bill nye:so these are peopleswimming near shore and they get swept out. and you can't see rip currentsfrom the surface of lakes, which is what catches people offguard because often they're just swimming along and they look upand they're in the middle of a lake and they panic. levar burton:so the idea would be to deploya couple of these in any given lake area and that informationwould feed back to the lifeguard

staff on shore? spencer ottarson:well, our buoy is actually amodified swim area buoy or swim area marker. so the idea is to replace thecurrent swim area markers on public beaches. and each of the buoysis a standalone system. so when it detectsa rip current, it just lights up the lighton top and beeps a siren. so each buoy along the lake,you'll know exactly where the

current is. bill nye:how far apart are they? julie xu:we are thinkingabout 40 feet apart. bill nye:that's typical for a swim area. julie xu:right. bill nye:so if a person's getting sweptout, whoop, whoop, whoop, then here or she knows,then everybody knows. get out of there. don't go over there.

bill nye:and plus maybe then to alertsomebody on shore to come help. julie xu:that too. bill nye:the whole thing isto swim sideways. that's the deal. cristin dorgelo:to get out. levar burton:and not get sucked out to sea. cristin dorgelo:so how did you guys getinspired to build this? is this part of a program yougot involved with at school? we're actually a part of thelemelson-mit inventeam program.

and inventeam are groups ofstudents, teachers, and mentors. and we're awarded up to$10,000 to make our inventions a reality. cristin dorgelo:wow. that's amazing. so it's partner organizationslike that that help students like you get a chance toget hands on with science and technology. what kind of science and techhad to go into this project?

what did you use in termsof science, technology, engineering, and math skills? spencer ottarson:well, there's a lotof electrical systems. and the buoy, oursensor, our flow meter, we have to send a signal to theelectronics box and process the signal and figure out whenthere's a rip current and when there isn't. bill nye:and it looks likeit's solar powered. spencer ottarson:it is.

it's also solar powered. so you can just leave itin the lake for all year. bill nye:but then there's abattery system probably. julie xu:yeah, 12-volt battery. bill nye:and it's got to be durable. julie xu:oh, yeah. bill nye:waterproof, i hope. cristin dorgelo:oh, yeah. with the waves.

levar burton:and corrosive insulated, yes? spencer ottarson:right. right now, it's mostly designedjust for the great lakes which is fresh water. but the plan in the future isto also adapt it for salt water because there's a lot of ripcurrents in the oceans as well. cristin dorgelo:so is this your firsttime at the white house? julie xu:yes. spencer ottarson:yes.

cristin dorgelo:are you excited? spencer ottarson:oh, yeah. julie xu:so exciting. cristin dorgelo:what are you excited for? julie xu:just everyone, all these youngpeople that are getting involved in science because, beingfrom a smaller community, we don't get to see thiskind of stuff often. and it's great to see everyonethat's getting involved. bill nye:the president may get achance to shake your hand.

julie xu:i mean, that's prettyexciting too, i guess. bill nye:he can hope. he can dream. what i can't get over, cristin,is the diversity of science programs that arerepresented here. levar burton:in these projects, absolutely. bill nye:what's the name of yours, sir? it's going real fast. julie xu:lemelson-mit inventeam.

bill nye:inventeam. cristin dorgelo:making ideas a realitythrough that $10,000. bill nye:so what year areyou in high school? spencer ottarson:i'm a freshmen atmichigan state university. julie xu:i'm a senior atwilliamstown high school. cristin dorgelo:where are you planningto go to school? julie xu:well, i'm wait listed atthe school that i would like to go to. so if anyone from the universityof chicago is watching right

now, i would really love to bea part of your great school. levar burton:come on, admissions! get on the stick! bill nye:chicago guy, yeah. what more do you need? she's at the white house. what time is it? they'll call any minute. cristin dorgelo:that's right.

they'll be calling. julie xu:i hope so. cristin dorgelo:well, i hone you guys enjoythe nice weather out here today. you guys are in the east garden. get to hang out outsideand demonstrate your project outside. and so i hope you havea great trip to d.c. it's been great to meet you. julie xu:thank you.

thanks a lot. spencer ottarson:thank you. cristin dorgelo:thanks. levar burton:congratulations to both of you. welcome. how are you liking the thirdwhite house science fair? kiona elliott:we're loving it. cristin dorgelo:and your names? kiona elliott:i'm kiona elliott.

levar burton:hi, kiona. payton karr:i'm payton karr. cristin dorgelo:peyton, it's good to meet you. levar burton:and you're both from thelemelson mit inventeam. kiona elliott:we're from the northeast highschool lemelson mit inventeam. cristin dorgelo:northeast high school where? kiona elliott:in oakland park, florida. cristin dorgelo:i see. so tell us about your project.

payton karr:we can actually show you ourproject if you want to see it. cristin dorgelo:awesome. we're going to walkright over here guys. bill nye:buckets of water. cristin dorgelo:nobody trip on any wires. bill nye:here. turn around. let the cameras see you. kiona elliott:our invention is an emergencywater sanitation station.

basically the idea of it is toprovide clean water for tropical areas in the event of a naturaldisaster such as haiti or really any tropical area. bill nye:why does it have to be tropical. kiona elliott:well, we made it for tropicalareas because it was actually designed after -- not thehurricane but the earthquake that happened in haiti. our team member was ona mission group there. and so we were thinking more,because we're in florida and

hurricanes are a big problemthere and in a lot of other tropical areas. so it's really designed to bean emergency water system for tropical areasafter a hurricane. bill nye:it's bicycle powered. love that. levar burton:show us how it works. walk us through the process. bill nye:i'm stepping back.

payton karr:well, one thing you did mention was that the bicycle powers the whole thing. we have a hub motor here onthe back of the bicycle which charges the battery, powerseverything here in the electrical box. it starts over here where youcan add water into this 200 and 100 micron mesh that will filterout basically sand and sticks and different things. levar burton:large particles.

payton karr:then it's pumped through this box and into that container over there. when it's being pumpedthrough the box, it is being sanitizedby ozone generator here. and once it gets inside the box,the second ozone generator is turned on to continuecleaning the water so it's not recontaminated. bill nye:so why this big metalcontainer -- enclosure? face the camera, please.

kiona elliott:well, the big containeris basically the way -- all of this is easilytransportable and can break down. bill nye:oh, this collapses. kiona elliott:it collapses, and can beplaced inside this container. then we close it up and, notonly does our bike power our system but it can alsotransport our system. it can be hitched to this bigtrailer thing and then taken to whatever area thatyou need it to be in.

levar burton:that's ingenuous. it's a delivery system anda filtration system in one. kiona elliott:and it can also chargecellphones or any electricity that you need. so if you need a laptop -- idon't know why you would need a laptop in the middleof that area. payton karr:for communications. levar burton:who doesn't want to beconnected these days? absolutely.

who doesn't wantto be connected. bill nye:plus you want to beonline if you can be. levar burton:and that's run offthe battery as well. kiona elliott:and the battery isjust rechargeable, straight from the bike. bill nye:and this is allcommercially available stuff, so it's going to be highreliability, we think. levar burton:ingenious. bill nye:is this commerciallyavailable, this bucket?

kiona elliott:yeah. we just bought itright off line. payton karr:the only thing we added to itwas the mesh filter which we kind of designed afteran embroidery hoop. kiona elliott:we took inspiration -- our boxis actually designed after a pizza box. fourteen teenagers working overa box of pizza, things happen. levar burton:pizza boxes as inspiration. bill nye:while they're needle pointing.

eating pizza andneedle pointing. levar burton:well done. payton karr:thank you. kiona elliott:thank you. bill nye:so you identified a needand you addressed it. payton karr:yes. bill nye:and any minute, it'sgoing to come up. has anybody approached you aboutmanufacturing these things? payton karr:well, we actually talkedto the red cross about it.

we still have to get backto them and answer some of their questions. but also, a missionarygroup approached us. they wanted to use it ontheir next mission strip. bill nye:fantastic. levar burton:amazing. cristin dorgelo:all right, guys. bill nye:you see, we're all speechless. wow, what did ido in high school?

cristin dorgelo:we're so impressed. so what are you guys going todo next, post science fair? kiona elliott:well, we -- i'm graduating. bill nye:where are you goingto go to school? kiona elliott:i'm going to theuniversity of florida. bill nye:oh, great. cristin dorgelo:and you? payton karr:i'm not graduating yet. i'm still a junior.

i plan to continue this. i really want to make itavailable to the third-world countries after disasters sothat we cannot just make it but actually have it put into use. kiona elliott:we're trying to get into contactwith the red cross more so that they can actually mass producethis and then have their groups, whenever there is a disaster,they can just take this along with them. i appreciate youshowing us your project.

levar burton:most impressive. most impressive. congratulations, ladies. change the world. levar burton:changing the world with science. unbelievable. well, thank you for joining usfrom the first live webcast of the white house science fair. thank you, levar andbill for joining us.

it's been great. bill nye:it's an honor. levar burton:pleasure. cristin dorgelo:keep watching. we're going to have morecoverage of the white house science fair today. and spread the news with#whitehousesciencefair. levar burton:white house science fair. peace y'all.

cristin dorgelo:bye-bye.
