In this astronomy activity (page 3 of the PDF), learners will examine the effects of gravity on a person’s pulse and explore how gravity can differ from planet to planet.

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this engineering/design activity, learners make a kite, fly it, and then work to improve the design. Learners explore how their kite design variations affect flight.

In this activity, learners work in pairs to measure each other's ankles with lengths of string.

This is a classic exercise for visualizing the scale of the Solar System.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.
