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

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 activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

In this activity, learners discover if carbon dioxide has an effect on temperature.

In this activity about engineering, nutrition, and physical activity, learners design and build a healthy bone model of a space explorer which is strong enough to withstand increasing amounts of weigh

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

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.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

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

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

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

In this activity (page 95 of the PDF), learners create Escher Staircase models similar to those that were used by Neurolab's Spatial Orientation Team to investigate the processing of information about

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this plant science activity, learners conduct four experiments to observe how plants respond to sunlight and gravity.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners will use cereal to conduct an experiment and investigate how decreased bone density is related to increased risk of bone fracture.
