In this experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this activity, learners are introduced to tree rings by examining a cross section of a tree, also known as a “tree cookie.” They discover how tree age can be determined by studying the rings and ho

In this activity, learners investigate passive solar building design with a focus solely on heating.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this activity, (on page 6 of the PDF under SciGirls Activity: Dinosaurs) learners participate in a hands-on fossil excavation.

In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

In this activity, learners compare the ways of life of Plains Native Americans who hunted and moved frequently to follow the buffalo herds, and Native Americans who farmed and lived in more permanent

In this activity (on pages 12-15), learners make a crater model and test the effects of weather (rain) on its surface.

Learners create their own piece of history by decorating, shattering, and piecing together a flowerpot "artifact".

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

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 activity, learners drop impactors onto layers of graham crackers!

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

This fun and simple hands-on astronomy activity lets learners make 3-dimensional models of the Earth and Moon.

In this simulation, learners explore how ocean currents spread all kinds of pollution—including oil spills, sewage, pesticides and factory waste—far beyond where the pollution originates.

In this activity, learners build and test a compass. Learners work in pairs and pretend they are stuck in the wilderness at night.

This lesson will helps learners answer the question: How does the bombardment of micrometeoroids make regolith on the moon?
