We only needed curiosity and silliness to find answers to this investigation! Does air have matter? We were going to find out with a plastic bag.

We opened the bag with flair....

...and scooped in air (we didn't blow it in!, just scooped).

Then we sealed the bag up tightly.

Then we put the bag to the test! The gas molecules pushed to get out.... we pressed against the gas to see if we could force it out.

Again.

And again.

And again.

And again.

....and again. And we didn't push it out. "Does air have matter, Maddie?" I asked.

"Yes!"

"How do you know?"

"Because air takes up space!" Air definitely has matter!
