Photosynthesis Lab

   Photosynthesis is a process used by plants and other organisms to convert light into energy, and nutrients. The chemical equation is 6CO+ 6H2O ------> C6H12O+ 6O2.  In this lab we took  spruce and placed it in to water. We then put baking soda into the tube with the plant, and placed this under the light. We then watched the test tube for signs of photosynthesis. When the water began to bubble  this showed photosynthesis. The more light we had and the longer the water was under light the more bubbles, meaning more photosynthesis. We then added phenol red to the test tube and covered it with tinfoil. Then we inserted a straw and blew into the straw and the solution turned yellow because of the carbon dioxide in the oxygen. though when the test tube was left in the dark it turned back to red. 


Here is a picture of the process of photosynthesis
