Unformatted text preview: Actua l Resul ts We know that oxygen is a product of photosynthesis; therefore we observed the release of oxygen bubbles from our hornwort clippings. All three test of our first experiment demonstrated similar results. The rate of photosynthesis clearly increased when baking soda was added to the experiment and further increased when a large amount of baking soda was added. The actual data are as following: Exp. 1 Baking Soda Trial 1 (Bubbles in 10s) Trial 2 (Bubbles in 10s) Trial 3 (Bubbles in 10s) No Amount 60 74 66 Small Amount 82 84 82 Large Amount 94 96 98 The second hypothesis that miracle grow would increase the rate of photosynthesis proved similar results. Adding a small amount of miracle grow to the experiment increased the rate of photosynthesis significantly. When we added a large amount of miracle grow we encountered approximately the same amount of bubble as when only a small amount of miracle grow was added. However the bubbles that evaporated from the pond weed after we miracle grow was added....
