My daughter did the experiment in RTR Unit 11 Day 4 today, and I have to say that we both didn't understand it. At first she shined the flashlight directly on the ball of brown paper so that it made a shadow of the "asteroid" on the white paper on the wall. She drew it like that in her notebook. But then we were talking about the difference between a "shadow" and a "reflection." The guide says that you should be making a reflection of the the brown paper ball onto the paper. I couldn't imagine how you could do that, since the brown paper won't reflect light onto something else. You can see light reflected off the brown paper ball directly, but then I'm not sure what the white paper is for.

Not sure if I'm explaining myself very well, but I wondered if anyone else could "shed some light" on how this experiment is supposed to be done?
