In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

When it rains, water can collect on top of and seep into the ground. Water can also run downhill, carrying soil and pollution with it.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

The goal of this Star Wars activity is to design and build a balancing device to help an Ewok escape the Imperial Forces by sliding down a tightrope to safety.

In this activity, learners make their own Sun tracker to explore how ancient civilizations around the world studied the Sun.

In this activity, learners use microarray technology to determine which genes are turned on and off at various points in the differentiation of pluripotent stem cells on their way to becoming pancreat

In this outdoor activity, learners explore UV rays from the Sun and ways to protect against these potentially harmful rays.

This activity requires a Pico Cricket (tiny computer).

Learners pour equal amounts of coffee, mineral oil, corn syrup, and alcohol into a beaker. The liquids resolve into stacked layers, and learners can infer which liquids are the most and least dense.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.

To discover the risk and protective factors involved in substance addiction, learners play a game of chance to determine whether a fictitious child is likely or unlikely to abuse drugs.

In this outdoor activity, learners saw sections from fallen trees, then count tree rings and look closely at patterns of tree growth.

In this laboratory exercise, learners will discover how many different plant hosts they can find that are infected by the same genus of a powdery mildew fungus, or how many different genera of powdery

A magic lantern is a light that projects an image onto a screen.

MarsBound! is an engineering simulation activity in which learners use realistic techniques to plan a mission to Mars.

In this optics activity, learners discover that not all shadows are black. Learners explore human color perception by using colored lights to make additive color mixtures.

Based on color photographic images, learners compare geological features on Earth and Mars to understand similarities and differences between the two planets, and consider the forces that created land

In this activity, learners create a large film of soap and experiment with what can and cannot pass through it.
