In this activity, learners learn about friction by making their own miniature hovercraft.

In this activity, learners use a simple 3D model to discover why the Moon has phases.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this activity, learners make a photographic image—without a camera!

In this activity, learners are challenged to design a planktonic organism that will neither float like a cork nor sink like a stone.

In this activity, learners use their sense of smell to explore the world on the nanoscale.

In this activity, learners make scale models of the Sun and Earth out of paper mache.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners explore the concept of insulation by trying to keep Olaf the Snowman from melting. This activity encourages critical thinking and problem solving.

This fun and simple hands-on astronomy activity demonstrates the shadow of the Earth as it rises as a dark blue shadow above the eastern horizon.

This is an educator-led demonstration of microarray technology using a model created from a pizza box and ping-pong balls.

In this activity, learners investigate the touch sensory system and discover how to plan and carry out their own experiments.

In this two-part outdoor activity, learners conduct a population census of squirting clams on a beach or mudflat, and investigate the clams' natural history.

In "Chemistry is Colorful" learners explore different materials through paper chromatography.

This activity provides a hands-on experience with a scale model, a relatively high viscosity fluid, and feeding behaviors.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.
