In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

In this activity, learners create their own obstacle course based on Bernoulli's Principle and try to get a floating ball from the start of their course to the finish line.

Heat makes some materials expand, and it makes others shrink.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners create air cannons out of everyday materials. Learners use their air cannons to investigate air as a force and air pressure.

In this activity, learners make a photographic image—without a camera!

In this activity, learners will take a step back and learn the history of the land they live on, and the people who used to live on it.

This activity is a sensory experience that recreates the sounds of a pond at night.

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

In this earth science activity, learners conduct a series of short experiments to explore how rocks change.

In this activity, learners will investigate the sounds of the heart.

These math posters have questions written on them, such as: How many colors can you name in a minute? or How many seconds can you balance on one foot?

In this activity, learners use design thinking to design and build their own bridge out of household materials including adhesives and/or connectors.

In this craft activity, learners create a string of cut-out moons and stars.

Using simple materials from around the house and recycled materials, learners will engineer a grabber device to pick up and put down objects that are at least 12 inches away.

In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this activity, learners explore the web of connections among living and non-living things.

Did you know that a bullfrog can jump a distance of 10 times its body length? Learn more about nature's most acrobatic amphibian, the frog, through this set of short, hands-on activities.

In this activity, learners build rockets and shoot them into the air by stomping on the plastic bottle launchers.
