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...

Is there more to evaporation than just less liquid? Show young scientists the energy transformation that occurs during a phase change through a series of simple experiments. Lab partners place drops of water, ethanol, and ethoxyethane on...

When life hands you lemons ... experiment on them! Green chemistry gurus compare extraction methods for essential oils through a lab activity. Lab groups use traditional distillation and liquid carbon dioxide extraction...

What makes particles attract? Here, learners engage in multiple activities that fully describe colligative properties and allow the ability to critically assess the importance of these properties in daily life. Young chemists...

How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third lesson of the series, learners conduct an experiment, demonstrating the flow of heat...
