GED Science: Naked Flying Space Critter!

Tuesday, September 9th, 2008

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… (more…)

GED Practice Question: Osmosis

Tuesday, May 20th, 2008

Ready for GED science? Are you? ARE YOU?!?! How about testing out your GED skills. So, last time you read about how osmosis is used to make MUMMIES!!! Basically, you put salt on the outside of a dead Egyptian pharaoh, and the salt sucks out the water. Why’s that? Well, there’s water inside all our cells, and the outside of cells is a MEMBRANE… and water can go in and out of it. So, what happens is, water tends to go to whichever side has the most of something dissolved in water. So, you pour a bunch of dry salt (something that dissolves) on the outside of the mummy…and the water says, “Hey! That salt doesn’t have any water dissolved in it. But we’ve got a lot of water in this cell here. We better balance it out by sending more water out into that salt!!!” And the water all goes out to dissolve with the salt. Ugh! A dried-out mummy is the result.

So, here’s a question that was on Yahoo answers. With everything you know, you can solve this question, easy.

“How does osmosis explain the fact that a watery syrup forms when you put sugar on strawberries?”

You’re using a GED skill called application. You’re applying what you know to a different problem. Can you solve it? CAN YOU? Click here to see the answer: http://answers.yahoo.com/question/index?qid=20080219200533AARCjin&show=7 

Did your answer say it better? Add your answer to the question on Yahoo!

And keep studying that science for your GED!
