Suggested Grades

1-3

Objective

This demonstration, will show students that air takes space.

Materials

  • glass jar
  • styrofoam packing peanut
  • clear basin of water (glass bowl or aquarium)

Method

  • 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.
