kids news." ♪ welcome to "teen kids news." i'm mwanzaa. >> and i'm jessica. here's our top story for this week. >> our earth is getting cluttered with more and more garbage. finding places to put it is becoming a big problem. siena reports on one company's innovative solution. >> only two manmade structures are large enough to be seen from outer space -- the great wall of china and the fresh kills landfill on new york's staten island. don't let the landscaping fool you. it's really the world's biggest garbage dump. in just one year, the average american creates up to 56 tons of trash. that's about the weight of 12 full-grown elephants. enter terracycle. a young company that's come up with a creative way to process billions of pieces of garbage. ceo tom zacki had just begun college when he came up with the idea. >> it was my friends and i, we were trying to grow these plants, and we couldn't make them work until we started feeding worm poop to them. so the first product terracycle created was liquid worm poop in a soda bottle, and then from there it grew. today we have 1,000 different products or more made entirely from waste. >> you've heard of recycling, but terracycle does something different. they call it upcycling. take a potato chip bag. there's three things you can do with a potato chip bag. you can throw it out, so that's putting it in the trash. there's no value being done there. if you took the potato chip bag and melted it into the plastic it's made from, that would be recycling. there you're only valuing the material, you're not valuing the shape it's in or the color or anything else that makes it a chip bag. upcycling, you're saying every aspect of the chip bag is valuable, and you're not going to melt it, you're not going to do anything to it, you're just going to make it into a new product. so recycling values only the material a product is made from. upcycling or reuse values the shape and the material it's made from. >> terracycle has been motivating schools across the country to get with upcyling. the company pays 2 cents for every piece of garbage the schools collect. all that trash and pennies mount up. terracycle pays out almost $200,000 a month for garbage. >> one of our parents actually brought it to our attention at the pto meeting, and from there it just took off. >> waste to be recycled is broken down into product types, called "brigades." >> we have a capri sun brigade. we have doritos and any lay's products. and when they are finished they just put it in the bin and at the end of several days we just collect it and send it over to terracycle. >> reporter: terracycle then turns the trash into all sorts of useful products. this pencil case is made from juice packs. this backpack is upcycled potato chip bags. >> i actually have a friend that has a pencil case that's terracycle, and i think it's pretty cool what they do, and it looks cool. >> reporter: the company is even branching out to fashion. >> i saw a doritos suit which was pretty cool, and they had a lot of different stuff that can be used from day to day just from trash basically. start thinking about garbage differently and realize that it's a raw material, something of value, not something that should just be thrown out. >> reporter: as you might say, "someone's trash is terracycle's treasure!" if you're interested in

a somewhat wacky educator. ♪ i grew up liking my science and math ♪ ♪ and you will too if you want to follow my path ♪ >> i've never been very good at sports, and when my kids started getting older, i got snookered into volunteering in one of their classrooms, and i realized that that was a great way of relating to the kids, and sort of instead of tossing around footballs we tossed around lightning. and so i started doing it in their schools, and then the neighborhood schools, and now i do it all over the country. >> reporter: john's electrifying performance is part of national lab day. president obama says it's important to encourage young people to be "makers of things, not just consumers of things." that's where a program called s.t.e.m. comes in. >> s.t.e.m. is four letters that mean -- s for science, t for technology, e for engineering, and m for math. organizations that come together with the main goal of inspiring middle school and upper school children to get more involved in the sciences, find out how exciting it is to be an engineer, understanding science technology, engineering and math, and hopefully we'll have more of the students now go into that path. >> how many of you are nerds, geeks, geekettes, nerdettes? aw, come on. how many of you are inventors? everyone's an inventor. >> the way i look at it, it's really good to have a scientifically aware society. you know, when you think about stuff the world is facing right now with energy and climate, the problems that we're facing, they're going to need policy, and we're going to need to conserve and everything, but we're also going to need new technologies. >> can you taste electricity? >> no. >> oh, yes you can. >> and if you can get kids to start thinking about their inventive skills, their science skills to solve those problems, it's going to be a whole lot easier. and i find that they get it, they get it. you don't have to teach them that, they already know this. >> which do you think is a better conductor of electricity -- santiago or the steel wool? >> the one thing that i always tell children is that you can't think of one thing, truly, that doesn't touch your life that doesn't involve engineering, science, math and technology. everything from the clothes that you're wearing to the glasses, to the hair bands, to the rubber bands. everything. that's the cool thing about engineering and science. it's not just something you learn, it's something you can actually use. ♪ itouch, i phone, i know you be wanting those things ♪ ♪ it's engineers like me that be designing that

get a little jiggy with it. >> reporter: no question, john's teaching methods are a bit unusual. >> you know what runs on a couple of millivolts? you. what happened? >> he died. >> no. they go woo, woo, woo. okay, they take you to the hospital. they hook you up. you'll be the weird box thing, stand up. so you do the beep-beep. your heart gets a little electric shock about once a second. did it work? oh, good. >> and what i think is really important is to get out there and get kids to really viscerally experience something. >> shake, shake, shake your head. nice look. >> thank you doctor, send me a bill. >> the most exciting thing was the generator with the high voltage. >> i knew a lot about electricity, but i never knew that it was all around the air and, you know, all the different ways that it could be produced. >> that was really cool when the lights were turned off and you can see all the sparks come out. >> doing hands-on experiments with vandergraph generators and learning about electricity is a perfect opportunity for students to understand how science works, and maybe having a job in the future with science. >> the success i see immediately is the faces on the children. their minds are starting to begin to determine that, "oh my goodness, i can do this. i can go into this field." ♪ been spending all our lives ♪ living engineering paradise ♪ been to grad

mostly a guy thing. but not these days. weight training is part of the picture for girls, too, especially girls who want to get in shape to compete in sports. >> they're just as into the fitness as the boys are. an athlete is an athlete in today's society, compared to boys or just girls, athletes are athletes. the bigger, the faster, the stronger is just as important for the girls as it is the boys. >> but as more girls get into weight training, their injuries increase. researchers at the ohio state university found weight training injuries among teenage girls are up 143% since 1990. >> and their increase was much higher than the increase among males. >> reporter: so the girls need to join the boys in making sure they train safely. and that starts with learning how to lift free weights correctly. because while older people tend to strain themselves by lifting, teens tend to hurt themselves by dropping. >> younger individuals were more likely to be injured using free weights, and they were more lily to sustain fractures and lacerations when they dropped the free weights on themselves. >> reporter: whether you're a boy or a girl, before you pick up the weights, pick up some safety advice. never lift alone. always use a spotter. start slowly, and build up to heavier weights. >> individuals that want to weight train, whether they're using free weights or machines, need to make sure that they work with a coach, a physical trainer, or personal trainer, an athletic trainer to learn the proper techniques. >> inhale, exhale. excellent. >> with the help of proper

league. >> the ivy league is a very hard group of schools to get into. >> they give you more opportunities than other schools. >> there's a lot of kids that their whole life depends on getting into an ivy league school. >> reporter: for the record, the eight ivies are harvard, dartmouth, brown, cornell, columbia, yale, princeton and the university of pennsylvania. to find out what's so special about them, we talked to lee stetson. he spent almost 30 years as an ivy league dean of admissions. >> the ivy league has this image of being one of the more elite and more respected programs in the country academically, which we like to think is true. >> reporter: but what most people don't realize is that the ivy league was originally defined not by scholastics but by athletics. >> we end up playing each other in sports, and that's really the bottom line. >> reporter: that may be how it started, but today the ivy league is seen by many as the country's most prestigious schools. they're certainly among the oldest. seven of the schools were founded even before the american revolution. there's a legend that ben franklin applied to harvard and was rejected. so he said he'd start a college of his own. and he did. founded in 1740, it was called the academy of philadelphia. later it was renamed the university of pennsylvania. today, penn has more than 23,000 students on campuses that sprawl over hundreds of acres. its wharton business school is world famous. and while there are many other excellent colleges around the country, for some only the ivy league will do. >> applications are at an all-time high. and only a fraction of those students will be accepted. >> but the more challenging it is, the more attractive a school becomes, and that's one of the reasons the ivies are more popular today. >> reporter: dean stetson adds that students and their parents shouldn't obsess on the ivies. they should broaden their options to find the college that best meets their individual needs. >> there are plenty of other options out there. >> reporter: the man who became famous for his experiments with electricity would probably be shocked to see how his little college
