week 4 May 15 2009 This week I have leard about forgs this week frogs have a grassy looking top and a yellow belly. They have many predators like snakes, birds, some fish, and mny othes. One thing that I have learend is that frogs have a wary muscular stomach for crushing the exoskellien on little bugs. I also lerend that a frogs tungh is hucked on the front of the mouth, this makes it so that ther tongh can g out farter then If it was hooked in the back like a plerson. One thing that I'm not shure about is why a steel ball does not fall faster than a wooden ball.

week 3 4/23/09 This week I learned about energy. energy can not be made or demolished it can only change pases. there also two tipes of energy kenic and potentiol. Kenic is the energy of motion and potential is stored energy. week 2 4/17/09 This week I learned about Ions witch are charged particles. It is made by a element that has all but a few electrons in its outer most shell and a element that has only a few in its outer most shell. What will happened is the one with only a few will lose a electron witch then makes it a charged particle the one with a lot will then gain the electron that was lost and it is then a charged particle. We also learned about compounds a compound is two elements hooked together shush as H2O witch is two Hydrogen’s and one oxygen. Hydrogen And Oxygen are elements but when put together they are compounds.
