Some general comments, thoughts and ideas.First, great job. I love educational environments that allow for hands on, somewhat "outside the box" thinking. I think it better stimulates the students minds when they get involved with the project.Things to measure or be potentially be concerned about:Response time of your solar cellReflections off of the dropped itemMaybe painting the inside of the tube in a light absorbing colorAs mentioned above, maybe using a laser pointer to a smaller sensorKnowing the response time of that sensorBreeze or other factors impacting the dropped item (putting the whole thing in a enclosure, for instance, to reduce unnecessary influences)Consistency of vertical position of the object during the drop (a ball has rounded edges. moving it left or right o…

Thanks! I have a group kids that I will try this out on and see what they have to add to the conversation. I wonder if there is a way to tie this into astronomy measuring a lunar eclipse?
