Curated OER
Water and Ice
Students make observations of ice as it melts. In this phase change lesson, students observe ice as it melts in a cup. They discuss their observations and place the cup of water into a freezer to change it back into ice.

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
Condensation
Introduce middle school science learners to condensation with this presentation. It begins with a brief explanation of the process and humidity, but does not present all of the details. Three demonstrations need to be set up ahead of...
Curated OER
Earthquakes
Students observe the melting of ice. In this phase change lesson, students observe ice as it melts. They discuss the process and create a Venn diagram comparing water and ice.
Curated OER
Ice Cream in a Bag
Students observe phase change of matter by making ice cream in bags. In this states of matter instructional activity, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take...
Curated OER
Thermodynamic Calculations for Chemical Reactions and Phase Changes
In this thermodynamics worksheet, students describe the reactions given and then determine the thermodynamic calculations. This worksheet has 14 problems to solve.
Curated OER
Heat And Heat Transfer
Learners 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...
Curated OER
Melting and Freezing of Water
Students differentiate the three states of matter. In this chemistry lesson, students analyze graphs of heating and cooling curve of water. They complete a lab report and discuss results.
Curated OER
Wet Dry Ice Lab
In this wet dry ice worksheet, students read the information about dry ice and phase change. Students perform an experiment in which they observe phase changes of ice. Students answer analysis questions as it relates to the phase change...
Curated OER
Water and Ice
Learners investigate what happens to solids and liquids when they change from one form to another. The amount od space taken by frozen water begins the discussion and students are led to formulate their own hypothesis to research.
