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...

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...

Water is the only molecule on Earth that can naturally exist in all three states of matter. The interactive simulation shows different molecules changing states of matter with the addition or removal of heat. Learners then see how...

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...

Students investigate what matter is and how it changes states.  In this physical properties lesson, students examine the vocabulary database and identify the characteristics of the three phases of matter.  Students perform a...

Students role play molecules in a container as the container is heated to develop a definition of heat and temperature. They also observe demonstrations of conduction, convection, radiation, and phase transfer. Using these observations...
