In this simulation, learners use M&M™ candy to explore radioactive isotope decay.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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

This activity was designed for blind learners, but all types of learners can use it to investigate heterogeneous and homogeneous mixtures and solutions, identify the differences, and explore the conce

In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

In this activity, learners discover how a cabbage juice indicator helps identify acids and bases, and how iodine indicates the presence of starch.

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 use two different techniques to estimate how many little things fit into one bigger thing.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.
