Answer 1

Conclusion
Doing this project we found that the color of light that caused a plant to grow faster is green. We think this was because it was not to dark and not to light. The plant that growed the slowest was the blue one. We think this because it was probably to dark for the blue plant to get the proper amount of sunlight. The second fastest growing plant was the red one and the third was the clear one.

Prediction
We thought that the green and blue covered plants would grow the best. We thought this because the blue one was the darkest and it would absorb the most light and that would cause it to grow faster. We thought that the green one would grow the best because the color of bean plants are green and that would help the green one grow faster because it absorbs its natural color. We also think that this information could be use in green houses to help grow plants faster.
