In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

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

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.

In this activity, learners create a necklace of wheat germ DNA. Learners add alcohol to wheat germ so that the DNA clumps together.

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

This lesson focuses on graphene and its electrical properties and applications.

Learners follow directions to construct a water-powered electrical generator using a turbine made from plastic spoons.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.

In this activity, learners explore how engineers work to solve the challenges of a society, such as delivering safe drinking water.

In this activity, learners explore how engineers work in a team to solve problems.

In this activity, learners explore how wind tunnels provide feedback to engineers about the performance and durability of products such as planes, cars, and buildings.

In this activity, learners simulate Otto von Guericke's famous Magdeburg Hemispheres experiment.

In "Chemistry Makes Scents," participants use their noses to distinguish between chemicals with very similar structures.

In this activity, learners use chemistry to produce weathered "antiqued" paper with burned edges. Learners first soak white paper in coffee and then apply a charring solution of ammonium chloride.

In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

In this activity, learners explore how infrared technology is used by engineers to create equipment and systems for a variety of industries.

Learn how to construct a light box by following simple figures and instructions. This guide includes tips on how to assemble a light box; related activities are featured in separate resources.

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.

This fun and simple hands-on astronomy activity lets learners imagine what would happen if our Sun were replaced with a black hole.

In this activity, learners explore how engineers have met the challenge of keeping foods, liquids, and other items cool.
