Exploring Air

Exploring Air | Science Fair Projects | STEM Projects
Come join us on an adventure to discover the properties of air! We'll use gallon jars, rubber bands, string, and plastic bags to explore the air around us.


The hypothesis is that air can be held in a jar.

Method & Materials

You will fill plastic bags with air, tie them to the jars, press down on the bags, and try to pull them out of the jars.
You will need gallon jars, two rubber bands for each jar, string, and strong plastic bags.


Our experiment showed that when the bag of air is tied to the jar, it is hard to push down on the air. When the bag is placed inside the jar, it is hard to pull out the bag. This is similar to a hammock with a person lying in it - to pull up the hammock, one also has to lift the person resting on it.

Why do this project?

This science project is interesting because it demonstrates the properties of air in a simple and fun way.

Also Consider

Experiment variations to consider include using different sizes of jars and bags, and using different materials to tie the bags to the jars.
