In this dynamic activity, learners build a catapult that launches projectiles, such as marshmallows.

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 activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien

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

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

This is a series of quick activities/demos and pre-assessment tools that evaluate learners' current understanding of microbes and introduce them to basic information about microbes.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

In this activity, learners explore how product design differences can affect the success of a final product -- in this case a bag for holding candy.

In this activity, learners will create glitter bottles with adult supervision. These are a fun way for little ones to practice observing and making comparisons.

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

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

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

In this activity, learners will explore the chemistry of cooking. They will learn about--and observe--the Maillard Reaction as they make their own browned butter.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
