Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.

Learners construct and launch paper helicopters.

Learners will do an experiment to determine which type of paper is strongest while focusing on variables and collecting data.

In this activity and/or demonstration, learners illustrate visually and physically that air has weight. Learners balance two equally-inflated balloons hanging from string on a yard stick.
