1. Properties of Air Foldable

2. (if starting with Zuber’s legal-sized paper, otherwise ignore this step) Take blank piece of paper, make a fold 3 in from the bottom, then cut that 3 in off.
Then fold it in half top-to-bottom (hamburger style)
Unfold it, then cut along the fold so you have two equal-sized pieces
Make a fold 3.5 in from the edge of one piece
Make a fold 4 in from the edge of the other piece
Insert the second piece into the first to form your foldable!

3. Front Square The front square gets your title: “Properties of Air”
Draw any pictures you want that represent “air” to you (maybe the wind or clouds, other things you might find in the atmosphere)

4. 1st Flap - Mass
With your foldable closed, write “Mass” on the exposed 1st flap.
Open the 1st flap and include
Definition of mass
Fact: air is made of atoms & molecules of gases
Answer: what happens to mass with increased altitude?
Draw picture: maybe scale with ballon on pg 10, or this  N2
CO2

5. 2nd Flap - Density
With your foldable closed, write “Density” on the exposed 2nd flap.
Open the 2nd flap and include:
Definition of density
Formula for density
Answer: What happens to density as altitude increases?
Picture: Maybe picture on pg 14, or one of these 

6. 3rd Flap - Pressure
With your foldable closed, write “Pressure” on the exposed 3rd flap.
Open the 3rd flap and include:
Definition of pressure
What do you measure air pressure with?
Answer: What happens to air pressure as altitude increases?
Picture: maybe pic on pg 11 and/or 13, or these 
