Putting vinegar and baking soda on the track.

Last week we completed our final experiments in our lab book. We made machines using all of the different kinds of energy we have learned about this semester. Experimenting with a variety of materials, we built machines that used kinetic energy or stored energy to release chemical energy by combining vinegar and baking soda. The students wrote about their machines in their lab books. If they did not finish recording their observations and ideas, please have them finish this week.

In our last class we will be learning about Archimedes, and the center of gravity. Please have students bring 2-3 smooth sticks 12-18 inches long, as well as objects they may want to attach to a mobile.
