Guiding Questions:
1. The process of photosynthesis
2. The method and procedures to develop photographs
3. What are the materials we should get for our experiment?
4. What are the results to tabulate?
5. what happens if the experiment fails? Any alternative or better methods?
6. The principle and photosynthetic mechanisms behind the development of photographs
7. is the development of photos related to the formation of starch?
Procedures:
1. Expose a photograph negative to sunlight for 48 hours.
2. Tape the negative onto a small card.
3. Place the set-up onto a leaf and expose it to sunlight for a day.
4. Remove the set-up and place the negative in a boiling water bath.
