1. What did you learn about air in this session (that took a couple periods)? Hopefully, you learned at least three BIG IDEAS!
2. What evidence do you have to explain the phenomenon that air takes up space (we didn't prove this in our video, but learned it in the first days of the lesson)?
3. What evidence do you have to explain the phenomenon that air has weight? 
4. When Mr. Solarz watches your video, will he be able to find problems with your "proof" that air has weight? Remember when we watched videos together as a class he mentioned a few ways teachers could trick their students - make sure you didn't use any trickery!
