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

This fun astronomy activity allows learners to experience finding stars in the night sky that will eventually go supernova. This activity is perfect for a star party outdoors.

In this indoor and/or outdoor activity, learners make an anemometer (an instrument to measure wind speed) out of a protractor, a ping pong ball and a length of thread or fishing line.

A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b

In this math activity, learners observe and sketch cracking patterns in pavement.

In this activity, learners will create a home for animal friends in their backyard using recycled materials. Some material suggestions include: pine straw and twigs.

Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

In this activity, learners use their feet to estimate distances. Learners calculate the distance of one step in centimeters by measuring 10 steps at a time to reduce measurement error.

In this activity, learners use a hand-made protractor to measure angles they find in playground equipment.

You may have tried to throw a curveball or a slider, or even a screwball, with an ordinary baseball and found it difficult to do.

In this math activity, learners jump and measure how far they can jump on different surfaces using different jumping techniques.

In this geometry activity, learners explore networks painted on playgrounds, such as a four square court, and draw their own.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

This is an activity about motion, power, air and Newton’s Third Law of Motion, which states that for every action there is an equal and opposite reaction.

In this activity, learners use cooperation and logical thinking to find solutions to network problems on the playground.

This activity demonstrates the importance of wearing a helmet to protect the brain. An egg is used to symbolize a head with the shell as the skull and the inside of the egg as the brain.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.
