In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.

This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this activity about computer programming, learners follow instructions in a variety of ways in order to successfully draw figures.

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

In this activity/demo, learners investigate biobarcodes, a nanomedical technology that allows for massively parallel testing that can assist with disease diagnosis.

This activity/demo introduces learners to aerogel, a glass nanofoam. Learners discover how aerogel is made and how well it insulates as well as learn about aerogel's other unique properties.

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

This is a demonstration you can use to show learners how valves and pumps work in concert to move blood through the circulatory system.

In this hands-on activity, learners use heat to shrink samples of polystyrene plastic (#6 recycle code). Learners compare the size and shape of the plastic pieces before and after shrinking.

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.

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

In this optics activity, learners discover how they can make glass objects "disappear." Learners submerge glass objects like stirring rods into a beaker of Wesson™ oil to explore how the principles of

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

In this quick and easy activity and/or demonstration, learners illustrate the effect of the weight of air over our heads.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

In this demonstration about force and motion, learners will explore the forces that affect a pendulum A simple model pendulum comprised of a ball and string demonstrates how pendulums work as well as

Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!

In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.

As a group, learners investigate three packages which are all the same size and shape, but have different contents. One is filled with foam, one is filled with wood, and one is filled with metal.
