| Explore | We know that plants need photosynthesis in order to grow. |
|---|---|
| Research Question | We want to test whether or not colored light will affect the growth rate of a plant. |
| Predictions | The rate of germination will increase under Red light |
| Experimental Design | Our plan is to take seeds that germinate fast and put it under different colors of light and measure if the rate of germination changes between them all. 1. Put seeds in a wet paper towel and put them in different colors of light. 2. Measure the rate of growth between the seeds. 3. After a week observe the root growth and leaf growth and color of the plants. 11/19 So far what we have seen is that our seeds haven't sprouted or grown any roots however photosynthesis is taking place due to the air bubbles that you can see in the bag and one of our control seeds has a new color to it. |
| Conclusion | The claim that we can make is that under different colors of light the rate of germination will increase. After 2 weeks we can conclude that the color of light does effect the rate of germination by seeing that the plants have sprouted and the colors of the seeds themselves have changed. And the plant itself also comes in darker colors of green. And we can continue the experiment to the actual bell peppers growing and seeing if the peppers colors will change under the different colors of light. To make this experiment better we can repeat it to validate our results. |
