Also, if you have some time to play with, do a google search of your favorite subjects in science. I am sure you can come up with much interesting information!
There are some cool experiments that you can do, that are VERY cool. You can stack water, by using water of different salinities, you can study surface tension with soap and pepper, and you can study volcanoes with baking soda and vinegar. If you want more information on any of these, just ask.
