| Research Question | How does changing the color of the water affect the photosynthesis of the plant? |
| Predictions | We think the leaf disks in colored water will rise slower. |
| Experimental Design | · Cut spinach leaves into 20 round disks with hole puncher · Infiltrate the leaf disks with plastic syringe · Take 2 50 ml cups and dill to the 40 ml mark with water · Put 1 teaspoon of red food coloring into one of the cups · Put the cups under 72 watt light bulbs · Put 2 drops of diluted dish soap into each of the 2 cups · Put 10 leaf disks in each cup · Record how many leaf disks have risen at the end of each minute until reached 20 minutes |
