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...

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
Learners observe phase change of matter by making ice cream in bags. In this states of matter lesson plan, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the...

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
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...
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
Students 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.

Science4 Us: Changes in Matter
Through an instructional video, games, and activities, students explore three types of change matter makes: physical change, in which only the shape of the matter changes; physical phase change in which matter changes to a different form...
CK-12 Foundation
Ck 12: Change of State
[Free Registration/Login may be required to access all resource tools.] Students explore how heat of fusion and heat of vaporization energy are used to create a phase change, and how a phase change can be used to do work.

Texas Gateway: Solids, Liquids, and Gases
Given descriptions, scenarios, or illustrations, students will distinguish between the compressibility, structure, shape, and volume of solids, liquids, and gases.
Concord Consortium
Concord Consortium: Stem Resources: Phase Changes
This activity reviews of states of matter, then relates them to atomic movement as it is affected by attractions between atoms and the addition of energy. Latent heat and evaporative cooling are also topics covered. Multiple-choice and...
Concord Consortium
Concord Consortium: Stem Resources: States of Matter
Using simulations observe what solids, liquids, and gases look like at the atomic scale. After observing the different states of matter at their atomic level, students will be able to conclude about the forces and attractions that exist...
