In this activity, learners explore how objects can have positive, negative, or neutral charges, which attract, repel and move between objects.

In this activity/demo about piezoelectricity, learners discover how some crystals produce electricity when squeezed.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this kitchen chemistry activity, learners explore the chemistry of crystals by making sugar crystals, consider a common chemical reaction type responsible for the rising of muffins and cake in the

In this activity (on page 1), learners role play as atoms to explore how atoms can be rearranged to make different materials.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

Get a roll of pennies, throw them on the ground, then remove those that only show tails, and repeat with the ones left over.

In this quick activity about predicting (located on page 2 of the PDF under Where's Nano?

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.

Learners mix vinegar and baking soda to produce a gas. With the addition of a bit of liquid soap, the gas becomes trapped in measurable bubbles.
