Don't look at anything below this break before completing everything above!
Classroom Demonstrations:
| Air has weight. | Air takes up space. | Air exerts pressure in all directions (not just down from gravity). |

Science Companion Activities:

Perhaps the teacher could use one ProScope to show how air particles are too small to see, even with a microscope (need something like an election microscope to see air molecules!).

To summarize...

Student-Created Video:
Does air have weight? IT DOES! How could you prove to others that air has weight? Plan and conduct a demonstration to provide evidence to explain the phenomenon that air has weight. It can be similar to ones you saw in this lesson, or completely different. Borrow items from the classroom to create your demonstration!
In addition, create a model (or models) that show that matter in all forms (solids, liquids, gases) is made up of particles that are WAY TOO SMALL to see - we call these particles "atoms". Use these models to explain this concept on your video.
Upload your video to your blog post entitled, "Properties of Gases," and then answer the following Reflection/Synthesis questions:

This would be a great time to do the Balloon Rockets Lab!
Reflection/Synthesis Questions:
- What did you learn about air in this session (that took a couple periods)? Hopefully, you learned at least three BIG IDEAS!
- 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)?
- What evidence do you have to explain the phenomenon that air has weight?
- 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!
