Week 3 April 23, 2009

1. In science class last week we learned many different things. One of the things that we learned in science is what the different kinds of energy forms are. We found out that there is kinetic energy and potential energy. We also learned that there are different kinds of those energy’s. An example for kinetic energy is thermal energy such as a fire and an example for potential energy is gravitational such as the earth. 2. Another thing that we learned in science this week is that we tested the thorey of that the product will wiegh the same as the reactants. In the experiment we did three different test to help prove this theroy. Only one test that me and my partner did that failed was only because probably all the other experiments we did the reactants where all covered so nothing could exscape but in this one experiment it was open to the air. 3. One question that I had out off all the diffrent things that we learned in science class this week is what type of energy is in a battery? Because when the battery is not in use the energy is stored inside its self but when the battery is in use such as in a clock is it still the same type of energy as it was when it was'nt doing anything?
