In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

In this activity, learners will observe magnetic properties and sort objects by them. This activity uses everyday items to teach learners about magnetic forces, poles and properties of magnets.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this activity (located on page 3 of the PDF), learners investigate the way water moves and how we can control and direct water.

This is an activity exploring color and color mixing.

Everybody loves bubbles, and this is the best bubble recipe ever!

This activity (on page 2 of the PDF under SciGirls Activity: Music and Sound) is a full inquiry investigation into sound frequency.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this fun and simple hands-on astronomy activity, learners construct a model of our place in the Milky Way Galaxy and the distribution of stars, with a quarter and some birdseed.

This activity (located on page 3 of the PDF under GPS: Lava Flow Activity) is a full inquiry investigation into the relationship between an object’s mass and the distance it is thrown by a catapult.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

In this activity, learners are challenged to design and construct a trophy for prize-winning sports equipment.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.

In this activity, learners explore electronics and motion by making a Scribbling Machine, a motorized contraption that moves in unusual ways and leaves a mark to trace its path.

In this activity, learners build a stuffed-animal zip line. Learners hold a cord against a wall, hook a cute stuffed animal onto it, let the animal slide down, and records its travel time.

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

This is written as a static display, but can easily become a hands-on experiment for learners.

This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ
