In this activity about magnetism (page 13 of the pdf), learners will experiment with magnets to explore how water and other liquids affect the strength of magnetic fields.

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

In this quick and easy activity, learners build an air cannon "drum" and see what happens when they "shoot" puffs of air at different targets.

In this card-based personal choice activity, learners review and sort COVID-19 and vaccine science information.

In this craft activity, learners will compare and contrast the major functions of plants and animals.

During this activity, learners will make different versions of "ooze" using varied proportions of detergent and glue.

In this activity, learners construct a playable kazoo from inexpensive materials. They will experience how vibration creates sound waves and music.

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

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

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 chemistry experiment, learners get to make a very bizarre substance using corn starch and water. Is it a solid? Is it a liquid? Or is it a different kind of substance entirely?

In this "Sid the Science Kid" activity from Episode 109: The Perfect Pancake, learners make applesauce to explore irreversible change.

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

In this activity about transfer of energy, learners get to build their own catapult using nothing more than a plastic spoon and some tape.

In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.

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 simple activity, learners discover how a mere piece of paper can be used to hold up the weight of a heavy book.

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

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

In this design challenge activity, learners invent a device that will make their friends and family ask, "What's buzzing?" Learners design an alarm with an on/off switch that is small enough to hide.
