Air Riddles in the Classroom: Quick Experiments

These riddles about air pair well with simple experiments that prove air is real. Blow up two balloons, tie them to the ends of a ruler balanced on a pencil, then pop one: the side with the full balloon drops, showing that air has weight. Stuff a dry paper towel into the bottom of a cup, turn it upside down and push it straight into a bowl of water. The towel stays dry, because the air trapped in the cup takes up space.

For a game, split the class into teams and read one riddle at a time. Give 2 points for a correct answer without the hint and 1 point with it, then ask the winning team to explain the science in the answer.
