In this chemistry activity, learners explore the amount of copper in a new penny. Learners use toilet bowl cleaner to hollow out the interior of a penny with zinc inside.

In this activity, learners explore two properties of gases: gases take up space and exert pressure. Learners assemble two flasks and a beaker, connecting them with stoppers and tubing.

In this chemistry activity, learners explore density by using four solids and 6 liquids to create colorful, layered rows.

In this (edible) activity, learners balance chemical equations using different kinds and colors of candy that represent different atoms. Learners will work in pairs and explore conservation of atoms.

In this activity, learners identify different classes of matter based on physical properties.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.

Learners measure a bottle full of air, and then use a vacuum pump to remove the air. When they re-weigh the bottle, learners find the mass is about 0.8g less.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.
