Changing Sugar
In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...
Curated OER
Heating and Cooling Curves
Students experiment with a pure substance and a phase change. In this heating and cooling curves lesson plan, students study the effects of heating and cooling a pure substance to observe a phase change. They determine both the melting...

Ice Cream in a Bag
Learners observe phase change of matter by making ice cream in bags. For this states of matter lesson, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the milk to...
Curated OER
Phase Change
Students compare the freezing temperature of two substances by conducting an experiment to freeze liquid ice cream. They vary the amount of salt used in the ice cubes during the freezing procedure to determine the change in the...

College Physics for AP® Courses
Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains multiple...
It's About Time
States of Matter: Solid, Liquid, and Gas
Solid, liquid, and gas: they all matter. Scholars create an animation of the various states of matter, experiment with the temperature of water as it changes states, and observe carbon dioxide as it changes states. The lesson also...

Selling The Molecular Kinetic Theory
Students investigate molecule movement according to the kinetic molecular theory. In this kinetic molecular theory lesson plan, students observe demonstrations showing that molecules speed up with increasing temperature and slow down...
Curated OER
Heat And Heat Transfer
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...
