Students complete an activity in which heat is transferred from hot water to metal washers and then from hot metal washers to water.

This resource is a video that accompanies the lesson plan, "Heat, Temperature and Conduction."

This resource is a simulation that accompanies the lesson plan, "Heat, Temperature and Conduction."

Students graph the temperature of an ice-water slurry as it is heated and discover the existence of another transition plateau.

Students graph the temperature of water as it reaches a boil and discover the existence of the transition plateau.

Students will investigate how temperature affects molecules and relate it to the science of Chinook winds, microbursts, and hurricanes.

In this lesson, students use direct observations and computer simulations to understand that heat is the transfer of thermal energy.

In this activity, students will demonstrate the effect that temperature has on particle motion and volume.

This resource explains the different states of matter and provides interative questions to test students knowledge.

In this activity, students will answer the question, "How will differences in temperature change the rate at which food coloring spreads throughout water?"

Scientists describe all matter on Earth as having constant molecule motion. Molecules in a gas are moving rapidly. Molecules in a liquid move quickly but not as fast as a gas. The molecules in a solid typically vibrate in place. Using a microscope, students should be able to observe random motion as they do this activity.

Students learn that particle movement changes as a substance changes from one phase to another. Students participate in experiments where they will look at water as it changes from a liquid to a vapor/gas and then back to a liquid. They write a hypothesis and descriptions about what happened, and work collaboratively to discuss, defend and clarify their writing.

This video describes and demonstrates the different structures, states, and properties of matter, including demonstrations conducting in space.

Students add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules. Students watch molecular model animations to make further observations and then draw their own molecular model.

This animation goes with the "Molecules in Motion" lesson plan. Students will learn that molecules in cold water move slowly and are close together while molecules in hot water move fast and are a little further apart.

This resource is an image showing water molecules at different temperatures. It is part of the "Molecules in Motion" lesson plan.

Students will design and conduct an experiment to see how temperature can affect the particle motion of water. The students will test molecular motion in different temperatures of water by adding food coloring to the water and observing the motion of the water molecules. This investigation will allow the students to see the movement of food coloring in water and how an increase or decrease in temperature will affect that movement.

Students will view a demonstration with a metal ball and ring showing that heat causes atoms to spread apart and cooling causes them to come closer together. Animations showing particles of solids and liquids are also provided.

This resource is a molecular model animation that accompanies the lesson plan, "Moving Molecules in a Solid."
