[Free Registration/Login may be required to access all resource tools.] Using the law of conservation of energy as a starting off point, students use the specific heat equation to perform calculations that relate mass, specific heat,...

[Free Registration/Login may be required to access all resource tools.] Students analyze and explain everyday examples that illustrate the laws of thermodynamics, including the law of conservation of energy and the law of entropy.

Learners are introduced to the concept of inertia and its application to a world without the force of friction acting on moving objects. When an object is in motion, friction tends to be the force that acts on this object to slow it down...

After learning about transfer of energy, specifically the loss of kinetic energy to friction, students get a chance to test friction. In groups they are given a wooden block, different fabrics, and weights and asked to design the "best"...

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...

Learn about one of the most misunderstood principles of physics, the second law of thermodynamics.

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...

You've probably noticed that the price of gasoline can fluctuate a great deal from one year to the next. Using good insulation material is one way to conserve energy and save money. Learn here which insulation materials work better than...

The role of insulation in preventing heat loss is discussed. The concept of thermal resistance is introduced and explained. Understandable language but no graphics.
