Learners investigate stress and strain by designing, building, and testing beams made from polymer clay.

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this activity, learners use clear nail polish to create a beautiful iridescent pattern on black paper. Learners discover that a thin film creates iridescent, rainbow colors.

In this activity, learners use colored candy to represent subatomic particles and make a model of an atom (Bohr model).

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners conduct an experiment to find the volume of one mole of gas. Learners capture sublimated gas from dry ice in a ziploc bag and use water displacement to measure its volume.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

In this activity, learners make a simple spring-like scale using a rubber band instead of a spring, and calibrate the scale in newtons (N).

In this chemistry activity, learners use common chemicals and metals to explore single replacement reactions.

In this activity, learners build unique yo-yos, which spin round and round without moving up and down.

In this chemistry activity, learners discover that the weight of the product of combustion is greater than that of the starting material.
