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.

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

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...

When you are craving an ice cold drink of soda, the last thing you want is to be stuck with a bunch of soda cans at room temperature. This fun science experiment sends you on a discovery to find the fastest way to cool soda with...

Students will look at what happens to different types of matter when they have a change of state.

Learn about kitchen chemistry alongside Ruff Ruffman. Young scholars can use the videos, games, and activities from The Ruff Ruffman Show to discover how by investigating solids and liquids and exploring heating and cooling, science can...

Why does ice float? In this article answer that question by learning about the topics of Specific heat capacity, evaporative cooling, and heat of vaporization of water.

Explains the concept of heat transfer and describes conduction, convection, and radiation which are the three modes of heat transfer. Includes formulas, examples, and applications.

A module that provides the definition of chemical property and examples of the chemical properties of matter using explanations, pictures, and review questions.

We all know that it takes energy to provide us with the basics of shelter: heating, cooling, lighting, electricity, sanitation and cooking. To create energy-efficient housing that is practical for people to use every day requires...

On this site, find a variety of materials to help students understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

This site contains an interactive activity in which students can learn about the three states of matter. There is also a factsheet that lists numerous properties of liquids, solids, and gases. The factsheet also uses water as an example...

Learn about the changing states of matter.

Although he didn't start studying physics until he retired from the clock-making business at age 30, French native Jean Peltier made immense contributions to science that still reverberate today. Even with the primitive tools available...
