Need a solid resource for teaching about states of matter? Science scholars go with the flow in a simple interactive that shows how intermolecular attractions determine a substance's phase. Pupils take control of the level of attraction...

Energize your phase change lesson plans! Add a short but focused interactive into the mix and watch as pupils experience how states of matter react to changes in kinetic energy. The resource tracks the kinetic energy of a cold solid...

Pour on the knowledge with an engaging states of matter interactive! Young physical scientists view the atoms within a liquid to explain what gives a liquid its unique properties. The resource allows users to highlight and observe two...

Welcome to the fast-paced life of a gas atom! Learners gaze at gaseous atoms up close using a colorful interactive. They can highlight two atoms and observe their movements within their container or follow the dizzying path of one atom...

Why are solids, well ... solid? Take a peek inside a solid substance with an easy-to-use interactive. Science sleuths examine the motion and position of the atoms that make up a solid before drawing conclusions from their observations.

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Building off young chemists' knowledge of the states of matter, kinetic molecular theory is the focus of the unit. Eight days of lessons including multiple demonstrations, one lab experiment, directed instruction, and worksheets,...
