In this lab, the different colors of light plants receive will be tested for the photosynthetic rate. Based on the equation of photosynthesis, 6CO2 + 6H2O + Energy --> C6H12O6 + 6O2, plants need carbon dioxide, water, and light energy to successfully complete photosynthesis. Photosynthesis is necessary for plants to create glucose, which is the plant's food. This is necessary for the plants to grow and to survive.

This lab combines concepts from physics and biology. The light wave aspect comes from the electromagnetic spectrum. Visible light is the only part of the spectrum that the human eye can see. This light is important for plants to carry out the biological process of photosynthesis. Each light has a different wavelength which allows us to see different colors. The investigation will find if light wavelengths have an effect on the rate of photosynthesis.
Hypothesis: If plants are exposed to different colors of light, then the plant that receives blue light will have the highest photosynthetic rate, because blue light waves are shorter which means more light energy will be absorbed by the plant.
