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.

This activity explores the main algorithms that are used as the basis for searching on computers, using different variations on the game of battleships.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

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.

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.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

This magic trick is based on how computers detect and correct data errors.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

In this demonstration, learners attempt to get a large coin through a small hole, the size of a smaller coin.

In this activity, learners will explore how a hydrometer works by building a working model and conducting experiments.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

In this activity, learners explore how distance can affect the way we perceive the size of an object.

This is a quick and simple demonstration about reflexes (second activity on the page).
