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

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.
