In this activity, learners make their own heat waves in an aquarium.

Use this model to demonstrate the goal of NASA's Kepler Mission: to find extrasolar planets through the transit method.

In this activity, learners will measure the length of a shadow and use the distance from the equator to calculate the circumference of the earth.

In this online interactive, learners use fossils to infer temperatures 55 million years ago, at the sites where the fossils were found.

This activity has learners interacting with live crayfish, but could be adapted for a variety of similar hardy and interesting organisms.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this activity (9th activity on the page), learners work in pairs to see how their perception of touch differs from reality.

This is a chemistry lab activity about solutions (page 7 of the PDF). Learners see firsthand how chemicals in a solution can combine to form an entirely different substance.

In this two-part activity, learners use everyday materials to visualize one mole of gas or 22.4 liters of gas. The first activity involves sublimating dry ice in large garbage bag.

In this activity about depth perception, learners create an optical illusion in a shoe box.

In this activity, learners discover a brain process called habituation.

In this activity, learners cut out and assemble wheels to explore how variations in fish body structures (mouth shape/position/teeth, body shape, tail shape, and coloration patterns) allow fish to sur

This quiz lets you estimate your annual radiation exposure.

In this activity, learners look at and touch marine animal skulls to compare them and think about what they eat.

In this activity (1st activity on the page), learners explore their sense of taste and the structure of the tongue by taste-testing various foods.

In this interactive activity, learners analyze seashells to explore phylogeny and evolution. Learners identify similar and dissimilar seashells to create a phylogenetic tree.

In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.

In this activity, learners will explore how and why weight distribution works.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
