Purpose: The purpose of my science fair project is to find out if roots grow differently when their gravity changes. I choose to do this science fair project because I enjoy doing experiments with living and growing objects. Hypothesis: The hypothesis for my science fair project is that the roots of the seed will keep adjusting when the gravity is changed and they will keep growing downward and the stem will keep growing upward. I also think the the more seeds are in one bag, the less they will grow because they are more crowded. ... ... middle of paper ... ...to Gravity."Boundless. N.p.. Web. 31 Oct 2013. .
