In this activity (on page 1 of the PDF), learners make a "mini-globe" to investigate the causes of day and night on our planet.

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 about the baroreceptor reflex (BR) arc (page 123 of the PDF), learners discover the importance of maintaining adequate arterial blood pressure through a role playing exercise.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

In this activity, learners investigate how wind can create surface currents and how waves move. Learners also discover how wind can affect oil spills.

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, the learner will experiment with the physics of sound production while making a sound making toy. The activity includes a video with step by step instructions.

In this engineering design challenge, learners animate a facial expression and make a machine (zoetrope) that plays the animation back.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

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).

The goal of this activity is to design, build and test a house or toy for an animal.

In this fun activity about spiders, learners build and design a spider from cardstock, straw, string, and pipe cleaners.

In this activity, learners (at least three) work together to explore the effects of atmospheric pressure.

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 quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.

In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.
