Air Takes Space #3
This demonstration, will show students that air takes space.
styrofoam packing peanut
clear basin of water (glass bowl or aquarium)
Float the packing peanut on the surface of the water.
Ask students what will happen if you place the jar upside down over the peanut in the water.
Place the jar over the peanut and push straight down into the water. The peanut will be pushed to the bottom of the water.
You can combine this with putting paper toweling in the bottom of the jar as both with show the same thing.
The air in the jar kept water from entering the jar (toweling stayed dry) and pushed the peanut before it to the bottom of the basin.
