Learners set up books with rubber bands stretched between the books. When two identical books are stretched apart and released, they move back toward each other an equal distance.

On the first night, I saw 5 stars in the desert. On the second night, I saw 10… What do you think I saw on the third night? Combine arts and crafts, literacy, and math by making a counting book.

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 math lesson, learners explore probability.

In this activity, learners construct a home-made journal with simple, everyday materials.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

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.

In this simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

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.

Learners examine what happens when a tube spins in two directions at once. They push on a cardboard tube causing it to spin along its length while at the same time turning from end-to-end.
