In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.

In this physics activity (page 8 of the PDF), learners will explore the concept of inertia by attempting to run and stop quickly.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.

In this activity, use standard playing cards to introduce learners to cellular interactions such as cell to cell recognition and signal and receptor specificity.

In this activity, learners make self-assembled polymer spheres.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

Learners investigate how the temperature of water affects its density.

Learners see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float.
