Generating a Question about the Moon
Written by: Katie Rodriggs

Asked small groups to create a question about the moon that they can continue to answer by observing the moon regularly. Most were curious about the shape of the moon, if it will get bigger or smaller and when it will be a full moon next. Others asked about moon visibility in the night or morning. Two groups had questions relating the moon visibility at night to the changing season of fall. We went outside and looked for the moon, but were unable to see it—the moon was not visible, but I made certain not to say “the moon is not here”. Outside Nathalie lead the pinhole camera activity with the sun. Inside the students were urged to draw a picture representing what we did and they were told they will have to find the diameter of the sun eventually. I was surprised that multiple groups came to the conclusion that the diagram had to do with triangles and then slowly came up with the proportion idea all on their own. I learned this class that reviewing a concept, even if you’re not leading it is extremely important! I had trouble with the technicalities of explaining why the two triangles were similar and setting up and solving the proportion. I fully understood how to do this last year, but a little review would have benefited my ability to help the students.
