In this fun hands-on activity, learners whip up a batch of cyber-dough (play dough) using math for measurements.

This is an activity about lung capacity. Learners will measure their own lung capacity using a homemade spirometer.

Straws and pipe cleaners are terrific materials for building models of pyramids and cubes.

In this activity, learners investigate whether more people are squares or rectangles. People with similarly sized heights and arm spans are classified as squares.

Create a “Find Someone” list, with about 10 items, each containing a shape, number, or measurement. Can you find someone in the group with hair about 4 inches long? Someone wearing parallel lines?

This activity (located on page 2 of PDF) introduces learners to the real size of animals using nonstandard measurement.

In this Cyberchase activity, learners make carpenter's squares and use them to measure square corners. Learners cut out the carpenter's square template and attach it to tagboard.

In this Cyberchase activity, learners use math to explore how parts of the body are proportional.

In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?

In this activity, learners will build the highest tower they can out of recycled materials.

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 investigate parallax, a method used to measure distances to stars and planets in the solar system.

In this activity, learners follow clues to find five puzzle pieces, then assemble them. This activity works well with a whole group, individuals, or families.

In this activity, learners use recycled materials to build a bridge that holds as many potatoes as possible. They investigate weight, height, strength, and measurement as they seek design solutions.

In this activity, learners create a map of a hidden surface using a "sounding stick" -- a technique similar to how underwater maps were once made.

Using a real-size sketch of a baby elephant's footprint, learners estimate, measure and record the width (diameter) and outside edge length (perimeter or circumference) of the footprint.

In this activity, learners mark their height on a height chart and discover how tall they are in nanometers.

In this activity, learners will explore how maps can provide information about a place and help us find our way from one location to another.

In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity, learners make an astrolabe, a device used for measuring altitude, including the height of objects in the sky.
