Speedy Sprouts
Overview
Objectives/Goals I was trying to determine whether an acidic, basic, or neutral solution would increanse the germination of a Bush bean. Methods/Materials I soaked six beans per solution and used a paper towel to wrap them up in. Results Drinking water, a netural solution, stimutated the germination the most and the rest of the solutions did best in the following order: hyrdrogen peroxide (acid), potassium hydroxide (base), and hyrdochloric acid (acid). Conclusions/Discussion the drinking water did the best while the hydrochloric acid caused the Bush beans not the germinate at all. It destroyed the inside of the beans, making it impossible for the beans to germinate. The potassium hydroxide did not stimulate nor prevent the germination process but still allowed germination to take place and the hydrogen peroxide did the second best of stimulating germination.
Summary statement
I was trying to determine weather a more acidic, bacis, or neautral solution would increase the germination of a Bush bean.
Help received
Chemistry teacher helped diluite the solutions
