In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

In this activity, learners observe the moon each night for a month and draw their observations in a Moon Watch Log.

In this activity, learners explore how the area of Arctic sea ice has changed over recent years. First, learners graph the area of Arctic sea ice over time from 1979 to 2007.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

In this outdoor activity, learners discover the wonders of the habitat surrounding them.

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

In this activity, learners explore the strength of different shapes. Fold paper into triangles, squares, and other shapes, then experiment with how much weight they can hold.

Learners use compasses to detect the magnetic field created by current moving through a wire. This is one of four activities learners can complete related to PhysicsQuest 2008.

In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

Learners use the current flowing in a wire to create a magnetic field that turns a magnet. Learners can use this property of electromagnetism to build a magnet-powered pinwheel.

Learners follow a three-step process to start their own rock collection.

In this activity, learners build bridges out of newspaper and tape to explore how structures are designed to bear loads.

In this engineering activity, learners construct sturdy geodesic structures out of gumdrops and toothpicks. Use this activity to explore engineering principles as well as sturdy shapes and triangles.

In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

In this design challenge activity, learners use tubes of newspaper to make a table that’s at least eight inches tall and strong enough to hold a heavy book!

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

Learners drop two different masses of play dough and observe how long it takes them to hit the ground.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.
