It's Our Air - 1-1 What Is Air?
WHAT IS AIR? ACTIVITY
Through a variety of hands-on experiences presented as stations in the classroom, students will discover properties of air, including that air has volume, mass, and pressure; that it is compressible and that it expands when heated. They will also learn about the major molecular components of our atmosphere (nitrogen, oxygen, argon), the four layers of our atmosphere, and that air contains water vapor.
ESSENTIAL QUESTIONS:
What is air made of?
What are some of the properties of air?
How can we demonstrate those properties when air is invisible?
Is our atmosphere homogenous or does it change with elevation?

WHAT IS AIR? VIDEO
Through a two-part video packed with demonstrations and animation, students will discover properties of air, including that air has volume, mass, and pressure; that it is flows, and that it expands when heated. They will also learn about the major molecular components of our atmosphere (nitrogen, oxygen, argon), the four layers of our atmosphere, and that air contains water vapor.
