Hands-on in the classroom, our first-grade scientists had fun experiencing the air that surrounds us.
The students used syringes, tubing, vials and more to show that air is indeed matter. It is a gas, and it is invisible! Still, air, we all learned, does take up space. It can be both compressed and expressed!
For example, we conducted experiments that showed that when air is compressed its pressure builds and that pressure can push other objects around.
In another observation, we dropped parachutes to examine how the paper increased air resistance, slowing down the effects of gravity.
We blew up balloons and puffed on feathers in our classroom. Air definitely shaped and pushed those objects.
Our young researchers recorded their observations and their data in science notebooks. Another week of active engagement in the first grade!
