This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

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 make models representing bones on Earth and bones that have been in space. They discover what happens to bones without proper exercise and nutrition.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this group activity, learners will mark important developments of life on Earth on a timeline (each foot in length representing 200 million years).

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 activity, learners investigate parallax, a method used to measure distances to stars and planets in the solar system.

This fun and simple hands-on astronomy activity lets learners explore the difference between telescope magnification and resolution.

“Exploring the Universe: Imagining Life” is a hands-on activity in which visitors imagine and draw an extreme environment beyond Earth, then invent a living thing that could thrive in it.

This fun and simple hands-on astronomy activity illustrates the value of supernovae in the universe.

This fun hands-on astronomy activity uses a variety of simple props to help learners understand why they see what they see in a telescope.

In this activity, learners discuss how life is defined and conduct a simple experiment, looking for signs of life in three different “soil” samples.

In this activity, learners predict whether a ball on Earth or a ball on the Moon bounces higher when dropped and why.

In this activity, learners create volcanoes like those they have examined on Earth and Mars through images taken by spacecraft.

In this activity, learners create channel features with flowing water, comparing their observations to real images of Mars and Earth taken by satellites/orbiters.

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

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.
