Science Project Idea for You: Photosynthesis
Cover up part of a leaf with a black paper with a paper clip.

After a week, cut the leaf off from the plant. To get the chlorophyll out, boil it in alcohol (there could be an improvement on this step, a better way to get out the chlorophyll). Then stain with Lugol's iodine solution, which tests for starch. You'll see that the leaf will turn all blackish except the part where you covered, cause there is no photosynthesis there, and therefore no starch.
