Gases in Our Atmosphere

The air in our atmosphere is made up of a mixture of gases. The air is mostly nitrogen (78%) and oxygen (21%). The remaining 1% is other gases such as argon, carbon dioxide, ozone, and water vapor.

We will be making a visual representation of the gases in our atmosphere. Please follow the directions below:

1.  Mark off a 10 X10 box of squares on a piece of grid paper. You should have 100 squares representing all of the gases that make up our air.

2.  Color in 78 squares to represent the portion of our atmosphere that is nitrogen.

3.  Use a different color to color in 21 squares to represent the portion of our atmosphere that is oxygen.

4.  Use a different color to color in 1 square to represent the portion of our atmosphere that is other gases.

5.  Make a key showing which color corresponds to which gas.

6.  Add a title at the top of the page.
