7. Photosynthesis • Jaha helped test for starch. What element did she put on the leaf and what color would it turn if starch were present?

8. Photosynthesis • Should she measure: • Bubbles of Carbon dioxide produced • Bubbles of Oxygen produced • Amount of sunlight that hits the plant • Dazhanae wanted to get in on the science fun too… • She wanted to test the rate of photosynthesis at different temperatures.
