bill weir and tonight, juju chang in new york city. this is "nightline," october 25th, 2012. >> good evening, i'm juju chang. tonight, it's a distressing thought. but internet porn may be replacing sex ed for kids in the digital age. a shocking percentage of pre-adolescent children are being exposed to cyber porn. it fills parents of pre-teens like me with dread. and add to that those explicit lyrics in hip hop and suddenly, the facts of life are x-rated. ♪ i can bed your rock >> reporter: it's lil' wayne in "bedrock," makes the vulgar seem normal. listen to winnifred, who is 12 years old. ♪ i can make your bedrock >> reporter: does she understand

what she's singing? >> yeah, we did realize how obscene it was, but we did, we got it, we knew what we were saying. when i can reach into my back pocket and basically pull out some porn, it's so easy and you can't really blame a bunch of children for not understanding how to deal with that. >> reporter: she told us lewd lyrics are the least of it. when kids her age are downloading pornography on their smartphones. it's porn before puberty. >> when i was in eighth grade, boys, mostly -- >> reporter: what -- >> they were watching porn on their school. during independent reading, they would do that. >> reporter: i have a migraine now. we met winnifred in a documently called "sexy baby." it explores the fact that 9 out of 10 children ages 8 through 16 have watched pornography on the internet. winnifred's friend danielle was 11 first time she stumbled onto

it. >> one black guy, one hispanic guy and a very blond woman and they were just, like, ferociously banging each other. it was very -- i mean, i came home, i was bawling my eyes out. i'll never forget it. >> it sort of came at her before she was ready. and in a very graphic way. and luckily, she has a really good relationship with her mother, who was able to say to her, let me explain what that was. >> reporter: according to "playboy," porn is easier to access than ever. 40% of adults said they watched porn 30 years ago. now, it's reached 80% saturation. it's moved from the dark periphery to front and center. >> that's what porn sex is, it's sport [ bleep ]. >> reporter: the documentary follows nicole, a former porn star who provides unlikely voice of reason. pointing out that porn doesn't involve true intimacy. >> it's definitely not making love. there's a huge difference. making love is the kind of sex

that you want to cry afterwards, because it is so beautiful. >> if parents are able to talk to their children about what real love and real sex later on is, most of the kids i know would trust our parents over two porn stars that we've never met. >> reporter: but the sheer volume of erotica coming at these kids have blurred the battlelines between mothers and daughters. >> you said you didn't want to see any slutty photos. >> reporter: winnifred's mother jenny says she's a them nis, trying to raise an empowered girl. >> we all know those women who went to college who hadeally strict paren that didn't let them experiment with anything and they went wild in college. "girls gone wild" is a we nonnonand so many of those girls come from a household in my opinion where they were tamp d down on. >> we're the first generation to have what we have. so, there's no one before us

that can guide us. i mean, we are the pioneers. i'm already bordering on inappropriate. >> reporter: it's clear the girls are pushing the sexual boundaries. winnifred and her friend danielle are getting ready for a lady gaga concert. >> slutty? >> that's good like that. >> reporter: and winnifred carefully kur rates her online profi propile, pushing her budding sexu sexuality. >> we make ourselves seem like, [ bleep ]. >> reporter: you posted a picture of yourself with a bra showing, very e verevealing, at age of, whatever it was, 12, 13. >> we are getting messages from everywhere that say, if you dress this way, you will going to be, either treated well or you are going to feel powerful. >> so, my message to my daughter is, sexuality is a beautiful

thing. you should embrace it. but it's yours. you don't want to abuse it. don't take it for granted. you need to find a balance. >> reporter: when i saw some of the outfits that winnifred was wearing, i thought, i would never let my daughter walk out of the house wearing that. >> we don't necessarily want her to dress certain ways, but at the same time, we're raising our child to be an independent thinker. >> reporter: how much is too much independence whenever click is a judgment call with potentially perment repercussions. >> i can put a very sexualized photo on facebook and make it so my parents don't know, but every guy at my school does. so, that does become a self-fulfilling prophesy, because when you make yourself look a certain way, people are going to expect you to be that way. >> reporter: and act that way. >> right. and if you don't, it's strange. >> the adult entertainment world

has completely infill rated the main stream. i do believe that on the digital age. >> reporter: call it the porn if i casal of american culture. it's why the filmmakers are edited a tamer version of "sexy baby" for educational abuse, to spark the healthy dialogue they see as vital. >> if children are exposed and if you cannot talk to an adult about it, you are going to be incredibly confused and really scared. >> our thanks to jill bauer and ronna gradus, the filmmakers behind "sexy baby." just ahead for us, are you looking for extra cash? well, look no further than the broken down computer. how can you make real money off your old electronic devices. so anyway, i've been to a lot of places. you know, i've helped a lot of people save a lot of money. but today...( sfx: loud noise of large metal object hitting the ground) things have been a little strange.

(sfx: sound of piano smashing) roadrunner: meep meep. meep meep? (sfx: loud thud sound) what a strange place. geico®. fifteen minutes could save you fifteen percent or more on car insurance.

>> announcer: "nightline" continues from new york city with juju chang. >> you know, it might be time you thought about re-evaluating what you keep in that junk closet. turns out, if you have an old digital camera, ipod or computer lying around, it may be worth a lot more money than you think. abc's sharyn alfonsi brings us the quickest way to turn old electronics into serious cash, for our series, "easy money." >> mary and steve have a cash flow problem. they've got two growing daughters. >> when you sleep, where do your feet go? they're touching. >> reporter: and not enough money to buy beds that will fit them. >> what do you want instead of these beds? >> bunk beds! >> reporter: they're short $700. but they're about to find the cash they need hidden in plain sight. hi! i'm sharyn! >> hi, mary. nice to meet you. >> reporter: nice to meet you. mary is a blogger and steve

works in individual yog if i. so, they've accumulated tons of old tech. this is jessica dolcourt. she's a blogger that writes about turning tech trash into hard cash. jessica says most family can find hidden dollars in those old electronics. >> things that are in high demand now and things that turn over. cameras. phones. laptops. >> reporter: what do you have? give us an idea. >> like, three old iphones, i think. i have an ipod, i have a -- i haven't touched it since i got my ipod. cameras. oh, my gosh. >> reporter: hard to throw that stuff away because you spent a lot of money. >> and i feel like maybe i'll use it for something some day. but it's been, you know, a year or two or three. >> reporter: so, we went hunting. >> iphone 4? >> reporter: yeah. >> you can get a little bit for this. >> yeah. >> hand it over. >> you can get a couple of bucks for these, too. this is better than nothing. >> reporter: who, how do you

turn it into gold? jessica offered a few tips. number one, everything's worth something. even if it's broken. what about this? >> believe it or not, you can still get a couple of bucks for that. >> reporter: broken screen? >> they'll take broken screens. >> reporter: well, almost everything is worth something. >> one of those old scanners. >> i would personally recycle it. >> done. >> reporter: not an antique or anything now? >> when did you buy this? >> reporter: tip two, sell the big stuff. computers and cameras, online. we check out the dozens of websites that will give you an instant offer, like gazelle.com. no action, no waiting. the lapstop? >> calculating -- 300 bucks. >> whoa. >> reporter: and we get $265 for the camera. we just made $565. less than 200 to get the bunk beds. so, we get that stuff off in the mail and take the old cell phones and the girls off to the mall. yep, the mall. tip number three, there's money

near the food court. this is called an eco atm. a self-serve robotic atm that gives cash on the spot for old mobile devices. mary got to work. >> first, let's do cell phone. >> reporter: the machine identifies what kind of phone you have and what it's worth. first, the old iphone. >> that's awesome. >> reporter: on average, most of us replace our cell phones every 18 months. so, it is estimated there are more than 278 million idle cell phones in america. we find out that even this broken old phone is worth something. >> what? oh, yeah. >> reporter: $37! there are current it will about 150 eco-atms around the country. 15 minutes after mary started scanning her old phones, the big payout. >> one, two, three -- $193! >> reporter: but we wondered, where did all those phones go?

e co-atms headquarters. >> we call this a sort and forward process. >> reporter: here, the phones are reassessed and resold. it's called e-cycling. what happens to all this stuff? >> 75% of everything that we get finds a life as a cell phone. about 25% is going to get smelted for the gold and platinum that's in the device. >> reporter: who is buying this stuff? >> a lot of different refurbishers. they fix them up and sell them to the sprints and verizons. >> reporter: altogether, the family made $758. more than their goal. and enough to get these. >> what is it? >> bunk beds! >> reporter: a good day for the family that led to a great night for the girls. i'm sharyn alfonsi for "nightline" in san diego. >> and that is worth every penny. our thanks to sharyn alfonsi. and just ahead for us, the

speeding school buses, caught on tape, barrelling down neighborhood roads at over 70 miles an hour. with kids on board. foot?" nd you a "who thinks about stuff like that?" "vince mahe grew up on two continents... and noticed that wherever you go, people have their hands full, but their feet free." "the result? a liftgate you operate with your foot." "code name?" "open sesame" "the all new twenty thirteen ford escape. it's what happens when you go further." he loves risk. but whether he's climbing everest, scuba diving the great barrier reef with sharks, or jumping into the market, he goes with people he trusts, which is why he trades with a company that doesn't nickel and dime him with hidden fees. so he can worry about other things, like what the market is doing and being ready, no matter what happens,

which isn't rocket science. it's just common sense, from td ameritrade. question seven will double it. rushern baker: question seven will add table games and... a new casino, generatingmi millions of dolls... every year, without raising taxes. leggett: and audits will ensure the money goes... where it's supposed to.

more jobs, and millions for schools. baker: question seven will be good for our kids... our teachers, and our schools. leggett: keep maryland money in maryland. baker: please vote for question seven. leggett: vote for question seven.

every morning, and every afternoon, you trust them with driving your kids to and from school. but now, shocking footage shows school buses karining down neighborhood streets, even running red lights with a full load of kids on board. abc's jim avila brings us this alarming look at bus drivers. >> reporter: parents trust them with precious lives. >> our bus driver is really good. >> reporter: so, when moms and dads see pictures like this, school buses barrelling through red lights, and caught hitting speeds 20 miles or more over the limit, it's shocking. >> 50 lives that you've just put in danger. >> reporter: this is baltimore. where our affiliate, wmar-abc 2 investigated hundreds of speeding and red light violations caught on tape. some of them had kids in the bus as they zoomed by the cameras. others did not. >> we took this video of these tickets. we took it to bus stops and showed it to parents as they stood there with their children.

they were stunned. they were alarmed. they couldn't believe that once they put their kids on the bus, that these things could happen. >> reporter: it's not just baltimore. our cincinnati affiliate bought a radar gun. >> no, way. >> reporter: they, too, were shocked at the number of speeding bus drivers all over town. >> scares me. >> reporter: no wonder it's scary. kids aren't required to wear seat belts. this ohio bus, with an interior camera, captured what can happen in an accident. an average of only five students die on board school buses every year. safer on the bus than in any parent's car. it's one of the main reasons seat belts aren't required. >> we've been able to create the safest vehicle on the road, statistics prove that, but the drivers have to understand they're driving a large, medium to heavy duty vehicle and have to practice defensive driving. so, we're not happy but i really think this will be an important message to all bus drivers. >> reporter: a bus driver clearly this bus driver in new york had not heard.

she wasn't speeding, but her students can tell she's been drinking. >> you can't passed the turn. >> what turn? >> the turn off this road. >> reporter: the on-board camera confirms the kid's suspicion. the driver is out of control. >> you have to stop. you have to stop. >> reporter: as the kids press, the driver's voice slurs more and more. >> you're not okay and i know it. just turn it off, please. >> no. >> you can't -- turn the bus off! >> no! >> reporter: finally, the kids take their safety into their own hands and escape through the rear exit. >> you can't get off the bus! we are okay. >> reporter: police report says the driver's blood level was nearly double the legal limit. >> i asked her, you're really not acting normal, are you okay? and she's like, i'm fine. and i said, it kind of looks like you've been drinkinging. >> reporter: a fightening drive home. kids jeopardized by the bus drivers who take young lives in their care for granted.
