In this lesson, students will use a simple experimental setup to test plant response to different wavelengths of light. Students will practice making predictions and observations as the experiment progresses. Students will ultimately observe that plants respond preferentially to certain wavelengths of light. Understanding this fact is key to growing plants in space where the gravitropic response is lessened or not a factor. After explaining the results of their experiment, students will engage in a Claim-Evidence-Reasoning writing exercise using a write up of a plant science experiment that was conducted on Space Shuttle mission STS-121.
