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

In this geology activity, learners create a model using a mixture of salt and sand inside a CD case. When the case is tilted or inverted, the mixture dramatically sorts into a layered pattern.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

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 demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this activity, learners create models of erosion and floods and learn to recognize both in their environment.

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.

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In this activity, learners explore clouds and how they form.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this space science activity, learners explore transits and the conditions when a transit may be seen.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.
