Photosynthesis is the process of transferring light into
nutrients. The chemical equation is 2n
CO2 + 2n DH2 + photons → 2(CH2O)n + 2n DO. In this experiment we took sprigs of
spruce and submersed them in to water. We then put baking soda and placed this under
the light. We then watched the test tube for signs of photosynthesis. The water
began to bubble and this showed 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. When it is left int the dark it changed back to red.
