In this activity, learners build a scale model of the solar system using a roll of toilet paper.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity about dinosaurs and survival, learners use scrap materials to create a miniature dinosaur habitat that includes a food source, water source, and shelter.

In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.

In this space science activity, learners work together to create a human-powered orrery to model the movements of the four inner planets.

In this activity (on page 4), learners create a submarine using a plastic sandwich bag. This is a fun way to learn about buoyancy and how captured gas can cause objects to float.

In this activity, learners create a tornado in a bottle to observe a spiraling, funnel-shaped vortex. A simple connector device allows water to drain from a 2-liter bottle into a second bottle.

In this activity, learners discover the difficulty of ocean exploration by human beings as they investigate water pressure.

In this activity, learners build a tool called an inclinometer that can find the height of any distant object, from a tree to the North Star.

In this activity, learners make flipbooks of drawings showing the progression of a Total Solar Eclipse.

Learners model the processes that formed some of Earth's largest mountain ranges: the Himalayas, the Andes, and the Alps.

In "Exploring the Solar System: Mars Rovers," participants learn about how scientists and engineers use robotic rovers and other vehicles to explore distant worlds, and experience some of the challeng

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this activity (p.7-8 of PDF), learners examine fossil formation.

In this activity, learners test to see if carbon dioxide is present in the air we breathe in and out by using a detector made from red cabbage.

In this physics activity (page 8 of the PDF), learners will make their very own working compass.

In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

In this activity, learners drop impactors onto layers of graham crackers!

In this activity, learners investigate the Moon's infancy and model how an ocean of molten rock (magma) helped shape the Moon that we see today.
