Hello _saint,

Welcome to Science Buddies! If you are planning to do a hands-on science project, please tell us more about your plans, including your hypothesis and what sort of experiments you have in mind.

Otherwise, the experts here at Science Buddies can not help with your homework problems!

Thanks!
