Once students undertake this project, your role is to help them understand the science of what’s happening by asking questions. I am always amazed that students cannot answer the most basic questions about the experiment, such as “What did the car do?” Until they understand that you will hold them responsible for looking, listening, and understanding, they will take the easy way out: “I don’t know.” If they say they didn’t see what happened, direct them to run the experiment again with the forewarning that you will ask the same question immediately afterward. This sharpens their acumen. Why this emphasis on observing? It is the most.
