In January, 7th graders planted beans for our Bean Plant Inquiry Lab, in which they designed their own lab to see what variables affect plant growth! Groups tested different variables, such as water source (filtered, tap, bottled), type of light (blue light, indirect sunlight, fluorescent), types of beans (lima, kidney, black) and cared for and measured their plants over the course of three weeks. At the end of the growth period, they analyzed their data using a graph and wrote Claim, Evidence, Reasoning (CER) explanations to answer their investigation question. They loved it!
