In this optics activity, learners build a spy tool to secretly view things over walls or around corners.

In this math lesson, learners investigate fractions by playing a game.

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.

The goal of this activity is to design the fastest sailboat or one that carries the most treasure.

In this activity learners will measure and manipulate flubber using different tools. Learners will explore volume and make observations about texture and shapes.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In this activity, learners explore the unseen force of friction and how surfaces can slow moving objects at different rates.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

Learners make their own simple slide rules out of paper and learn how they work.

Learners estimate how many small triangles will fill a larger shape. Then they use a triangle stamp (or stencil made from a file folder) to fill the larger shape with triangles.

In this math activity, learners predict how many pom-poms they can toss inside a circle from three feet away. Use this activity to help learners explore probability.

In this activity (3rd on the page), learners conduct a series of tests to find out which of their eyes is more dominant.

Learners describe objects in a room using only numbers and shapes. They can measure the object (like a desk) and make a list of facts about it (e.g.

This activity is a whole-group kinesthetic demonstration that shows learners what it means to be in a "risk group" for developing heart disease based on family history and genetics.

In this activity, learners will take a walk with their family and incorporate a scavenger hunt. They will explore topics like ABC’s, numbers, colors, and shapes as they search for related items.

In this activity, learners will make and launch feather rockets. Lerners will use science process skils such as making predictions and measuring while launching the rockets.

In this engineering activity, challenge learners to build a tower out of 10 sheets of newspaper and 3 feet of masking tape, which can hold a golf ball balancing at the top.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

In this activity, learners will explore how and why weight distribution works.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.
