This resource is an animation that accompanies the lesson plan, "Changing State - Evaporation."

This resource is an animation on the different angles of ice that accompanies the lesson plan, "Changing State - Freezing."

This resource is an animation on ice structure that accompanies the lesson plan, "Changing State - Freezing."

Students will mix ice and salt in a metal can to make it very cold. They will see the liquid water and ice form on the outside of the can. Students will watch an animation of water molecules arranged as ice.

This resource is a video that demonstrates the effects on various objects when they are placed in liquid nitrogen. The video accompanies the lesson plan, "Changing State - Freezing."

This resource is a video that shows the difference in melting rates between a regular ice cube and a piece of dry ice. The video accompanies the lesson plan, "Changing State: Melting."

This resource is a video that compares the reaction when dry ice is placed in cold versus hot water. The video accompanies the lesson plan, "Changing State: Melting."

This resource is a video that shows what happens when a piece of dry ice is placed in water. The video accompanies the lesson plan, "Changing State: Melting."

This resource is a video that compares the rate of melting when ice cubes are placed on aluminum and foam surfaces. The video accompanies the lesson plan, "Changing State: Melting."

Students will see a small piece of ice melt on an aluminum surface. Students will explain the energy transfer and molecular motion which cause the change in state from a solid to a liquid.

This resource is an animation that accompanies the lesson plan, "Changing State: Melting."

Sample Learning Goals
Explain how two gases mix.
Design an experiment to find the factors which affect the rate of diffusion.

Students use drama to model science ideas about atoms and molecules, transferring heat and the process of combustion.

Students develop a concept map to summarize current ideas about states of matter after reading an online article.

In this kinesthetic activity, students are introduced to four of the states of matter: solid, liquid, gas, and plasma. It also demonstrates how the addition of energy can transform matter from one state to another.

In this activity, students will examine how temperature affects the movement of molecules. Then, they will use these observations to pick the best air and ice temperature for the hockey game.

Sample Learning Goals
Describe the behavior of the gas particles in the box.
Identify the relationship between pressure, volume, temperature, and number of gas molecules.
Describe the relationship between particle-wall collisions and pressure.
Predict how changing temperature will affect the speed of molecules.
