Discovery Time: Tracks
Source Institutions
In this activity, young learners, (2 years and up) explore animal behavior and adaptations by providing a "track trap" and observing the signs animals leave behind.

Air Lift
Source Institutions
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.

Habitat Observations
Source Institutions
In this outdoor activity, learners discover the wonders of the habitat surrounding them.

Egg-stra Strength
Source Institutions
In this physics activity, learners will investigate the strength of egg shells.

Jump to It!
Source Institutions
This is a quick and simple demonstration about reflexes (second activity on the page).

How to Test The Strength of Shapes
Source Institutions
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.

Bookshelf
Source Institutions
In this activity, learners use simple tools to build a bookshelf with a built-in bookend.

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

Dancing Compasses
Source Institutions
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.

Discovery Time: Trees
Source Institutions
In this activity, young learners (2 years and up) explore tree structure and biology. Tree products are explored by painitng with fruit.

Paperfolding Polyhedrons
Source Institutions
In this activity (on pages 55-66 of PDF), learners fold paper into origami shapes and then combine several identical shapes into a three-dimensional structure.

I Spy, Describing Insects
Source Institutions
In this activity, learners observe and describe the physical and behavioral characteristics of insects, including crickets.

Magnet Powered Pinwheel
Source Institutions
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.

Start a Rock Collection
Source Institutions
Learners follow a three-step process to start their own rock collection.

Building Bridges
Source Institutions
In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.

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

File Card Bridges
Source Institutions
With two stacks of books and a few rolls of pennies, build two kinds of bridges--a beam span and an arch span--and see how much weight each of them can hold.

Fly on the Ceiling
Source Institutions
In this math lesson, learners play two different games to help them understand coordinates. First, learners read the book, "The Fly on the Ceiling," by Julie Glass.

Twist & Shout
Source Institutions
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.
