| Research Question | How does a blue-colored light affect the rate of photosynthesis from plant discs? We came to this question because we were interested in how light affected the photosynthesis rates on plants and chose the color blue because blue is better than red. |
|---|---|
| Predictions | We hypothesize that the blue-colored light will lead to a higher amount of photosynthesis in plants as opposed to the clear-colored light. We think this because in an online lab we did, blue-colored light had higher photosynthesis levels. |
| Experimental Design | Our independent variable is the color of the light (clear or blue). Our dependent variable is the photosynthesis rate. We will measure this by seeing how many plant discs float. The variables that need to be held constant are Amount of Light, Distance from Light, Amount of Water, Amount of Carbon Dioxide, and Type of Plant. |
