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

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.

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 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.

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

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.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

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 activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this astronomy activity, learners create a model of the solar system using beads and string.

In this activity, learners act as the Earth and observe how different angles between the Sun, Earth, and Moon affect the phases of the moon we see each month.

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

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