A tutorial reviewing the states of matter and the effects of heating and cooling matter in the different states. (Note: some of the links may not load in the archived version of the site.)

In this activity, students will investigate whether the temperature of water affects its density. Students will place colored hot and cold water in a cup of room-temperature water to see that cold water sinks while hot water floats. Then...

When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as...

Nanook wants to learn to cook. In order to cook, she first needs to learn how things can change when they are heated or cooled.

In this lesson, students will investigate how different materials changed when heated or cooled. The process in developing the investigation will be inquiry based. Students will have the liberty in choosing the materials and devising how...

This page is a lab that will teach you about heating and cooling curves.

This simulation allows students to make observations about how particle motion changes as the overall temperature of a liquid changes.

In this instructional activity, 3rd graders will explore heating and cooling through pantomime. By enacting the effect of sunlight on a snowman and a growing seed, students will learn scientific information kinesthetically.

[Free Registration/Login Required] Use the interactive cooling curve graph as a tool to answer two challenge questions about temperature change in the fossil fuel, Naphthalene.

Students come to see the exponential trend demonstrated through the changing temperatures measured while heating and cooling a beaker of water. This task is accomplished by first appealing to students' real-life heating and cooling...

Observe how heating and cooling affect the density of water. Combine the concepts of temperature, molecular motion, and density to learn that hot water is less dense than room temperature water and that cold water is more dense.

With the help of simple, teacher-led demonstration activities, students learn the basic physics of heat transfer by means of conduction, convection, and radiation. They also learn about examples of heating and cooling devices, from stove...

Explore how heating and cooling iron, brick, and water adds or removes energy. See how energy is transferred between objects. Build your own system, with energy sources, changers, and users. Track and visualize how energy flows and...

Based on experimental observations, students describe, on the molecular level, why the liquid in a thermometer goes up when it is heated and down when it is cooled.

This activity will show students how objects change size when heated and cooled. Students will observe a metal tube have expansion and contraction.

Students are introduced to passive solar design for buildings--an approach that uses the sun's energy and the surrounding climate to provide natural heating and cooling. They learn about some of the disadvantage of conventional heating...

Students observe, on a molecular level, how heating and cooling affect molecular motion.

Students observe and describe, on the molecular level, how heating and cooling affect the motion of molecules in a solid.

Investigation shows that gas takes up space and has mass, and that the motion of gas molecules is affected by heating and cooling.

Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures?

In this lesson, 3rd graders reflect on who they are by listing their likes and dislikes, beliefs, hobbies, etc. They then create a rubbing of their name and add rubbings of objects they like, along with symbols and sketches. Next, they...

One way to conserve energy in a building is to use adequate insulation. Insulation helps keep the hot or cool air inside or outside of a building. Inefficient heating and cooling of buildings is a leading residential and industrial...

Eight different types of energy that can convert into thermal energy are described. A movement activity and an experiment are included in this overview of thermal energy.

Different types of hot dogs will cool at different rates after they have been cooked. This activity takes the first steps in investigating this phenomenon by measuring the rate that a warmed hot dog cools. Students can compare the...
