Want to learn some GED science, and find out how the government’s gonna invade your privacy in the future? One single strand of hair… and THEY can tell where you were all last year? Can they tell what planet I was abducted to, that’s what I wanna know! Yeah, it’s true, a new science study can figure out where you were by lookin’ at your hair. Continue reading
Know what I always thought was totally enlightening? A lava lamp! Yeah, they’re so kewl. I don’t know if you’ve got one, but you turn it on and the stuff all flows all meditative like through the water… and the whole thing glows. Totally trippy!
Seems like, lava lamps is really science! Who knew? Here’s how it works. So, the lava lamp’s got two things in it, right? There’s the liquid, and then there’s the thicker stuff that goes up and down. How’s it move? It looks like magic! But it’s really science, see?
Here’s the physics: Heavy things sink, and light things float. Sounds really non-scientific, right? Cuz like a rock will sink, but a leaf will float. Science guys say, “Dense things sink, and less dense things float.” That’s cuz a really tiny rock and a really gigantic, humongous leaf might weigh the same… but the rock is smaller. It’s got more weight for its size. So it’s dense.
Anyway, heat makes things expand… they get bigger. So when the thick stuff in the lava lamp gets hot, cuz of the bulb at the bottom of the lamp heats it up, it expands. That means it’s less dense. So it goes up…. then it gets to the top, cools off, gets more dense again, and falls down. Up and down, up and down, as it gets hotter and colder. Kewl!
You can even make your own lava lamp at home. That’s one thing I like about science, is you can build things with it. Here’s a link that shows you how: http://www.oozinggoo.com/howto.html
And if you want to know some cool non-science stuff about lava lamps, here some info about the guy who invented them! He sounds like a bit of a wacko…. like me! http://inventors.about.com/library/weekly/aa092297.htm
Dudes! So, like, part of GED science is studying your own body… and health, and stuff like that. Like, did you know I’m allergic to peanuts? Seriously. Get those things away from me! I found a science article about peanut allergies, too… Some scientists did a study about kids allergic to peanuts. And guess what the solution is to peanut allergies that they found? PEANUTS!
Here’s how it works… the kids ate a little bit of peanuts every day, and their bodies sort of got used to dealing with them. They built up a tolerance for peanuts. Man, I wish I’d done that when I was little! But be careful, this article says that it’s just a study for now… and no one should do it without a doctor. You don’t want to set off your peanut allergies. No kidding! The article’s called “Children Can Complete Treatment For Peanut Allergies And Achieve Long-term Tolerance, Studies Suggest”
Here’s a GED Practice question from the article… First, read this paragraph from the article:
Duke and Arkansas Children’s Hospital began enrolling patients in studies five years ago to determine if incremental doses of peanut protein could change how the body’s immune system responds to its presence. The doses start as small as 1/1000 of a peanut. Eight to 10 months later, the children are ingesting the equivalent of up to 15 peanuts per day. The children stay on that daily therapy for several years and are monitored closely.
So, based on this study, what might a scientist hypothesize would be an effective treatment for an allergy to milk?
1) a regular daily dose of 1/1000 oz. of milk
2) a daily dose of milk, beginning at a very small quantity and slowly increasing
3) a daily dose of milk, beginning at the maximum tolerable quantity and slowly decreasing
4) a daily dose of 10 oz. of milk for 8 to 10 months
5) a small dose of milk administered at random intervals
So, what’d’ya think? Read more to find the answer… Continue reading
D00dzzz! Hey, I’m always lookin’ for new reasons to have a part-ay! And there’s a good one this month… that’s Darwin Day! Whoo-hoo! It’s Darwin’s B-day. And it’s a big one… his 200th. Cool. Science and partying, together at last. Continue reading
Hey, Dudes! The GED science test’s got a lot of stuff on it… but one thing you really KNOW is gonna be on there is science experiments. I love science experiments, dudes. Like, mad scientist stuff, you know… making invisibility cloaks and glow-in-the-dark slime. But you gotta know something about how experiments are done…and why… and that means understanding the scientific method. Continue reading
Hey, kewl dudes! How’s all your GED science goin’? I seriously wanna talk about monsters, but I gotta say somethin’ first to all you GED studiers. I like, got a comment that science is totally whack, but I couldn’t post it (sorry dude) cuz of swearing. I get it, totally. I mean, science used to make me swear all the time, till I realized that all the kewl science fiction is based on science… and all the kewl stuff we got like iPods and iPhones and XBoxes and, hey, even the comment box to put your swearing into is all based on science. Yeah, I know, science’s got math and sometimes it’s tough to understand. But it so totally rocks, dudes, cuz of all the weird stuff that can CHANGE THE WORLD! Continue reading
Dudes. Dudes! DOODZ!!! Totally. I love this weird GED science stuff. I read this article, it’s really kewl. So, no one can live in space, right? Like, if you go out without your space helmet, your head will explode or something. Not to mention you can’t breathe. There’s no air or nuthin. So, it’s impossible to live in space, right? RIGHT?!?! WRONG!!1!11! Okay, here’s the science stuff… Continue reading
Reading is one of the skills the GED measures most. You have to read to take the test… and if reading is hard for you, the GED tests for reading, writing, social studies, science—and even math—are going to be hard. So, what do you do to become a better reader? Continue reading
So.. static electricity!!! Makes your hair stand on end! It’s all science, I tell ya’, GED science! Yes, it is. And you can prove it. See, there’s this thing called a Van de Graaff Generator. Kewl science name, right? It’s a MYSTERIOUS object that makes your hair stand on end! No joke. Continue reading
I got a GED science experiment for you! Forget books for studying for the GED test…. I learn things by doin’ them! That’s right. Get out from in front of your computer, cuz here’s a GED experiment anyone can do right in their own home. Ok. Here it is. Now, do this before you read anything more. Get up from your computer. You got to be wearin’ shoes, so put them on if you’re barefoot! Then, stand on the carpet and rub your feet back and forth. Now, touch the doorknob. Continue reading
