Take a look at your journal. Make sure you have collected all your notes, and that these are sufficiently organized that you will be able to make sense of them later.
Things you might include are
What question did you think of that could be studied, or observation could you make that is interesting or unexpected?
How would you use these activities (or activities like them) in the classroom?
How would you relate the physics concepts in the course to applications in everyday situations?
Share ideas for more investigations that could be done using common objects and the materials in the kit.
