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 activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

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 activity, learners explore the different salinities of various sources of water by taste-testing.

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

In this quick activity/demonstration about density, learners examine what happens when two cans of root beer--one diet and one regular--are placed in a large container of water.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

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.

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

The demonstration/experiment provides quick proof that air has mass.

Learners will understand the relationship between climate change and sea-level rise.

Are balloons porous or non-porous? In this activity, learners watch an entertaining Mr. O video and conduct a simple experiment to find out.

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