In this activity, learners build models of atoms and molecules, then consider their role in different phases of matter, density, and mixtures and solutions.

In this adapted version of poker, learners practice writing chemical formulas by playing this chemistry card game.

In this chemistry demonstration, learners observe a chemical reaction that produces a colorful effect.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this activity about electricity, learners produce a spark that they can feel, see, and hear. Learners rub a Styrofoam plate with wool to give it an electric charge.

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