Photosynthesis Lab
Procedure
1. Make hypothesis
2. Cover some leaves in cellophane, some in black paper and some uncovered
3. Cut off experimental leaves
4. Extract the chlorophyll from the leaves
5. Rinse in water, Place in petrie dishes
6. Cover in iodine
7. After 1 minute place on paper towel and record results
Grading scale 1 low - 10 high

Materials List
- black paper
- Cellophane (red)
- petrie dishes
- Pipets
- Iodine
- Scissors
- Sharpie
- 2 plants 1 green leaf 1 red leaf
- Test tubes
- Paper towels
- Spatula
Hypothesis
I think the plants covered in the red and black paper will not produce as much starch as the uncovered one because the red one isn't getting all the colors of the visible light spectrum, and the one covered in the black because it isn't getting light hardly at all and what ever little light the leaves get the intensity is low.

Reflection
This project was quick and only took a few minutes on the first day and then like 20 minutes on the other day. this project was I thought it was an okay project and I did learn some things but overall it wasn't fun and kind of boring.
