Heat Flow

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction, convention,...

Review heat transfer with your seventh graders and guide them in making a practical application. Learners use a paper cutout spiral to locate convection currents in the classroom and throughout the school. They record the temperature at...

Heat up some interest in solar energy. Young engineers create a water heater that runs on solar power (simulated by a lamp). Using thermometers, they determine the change in temperature before and after the water goes through the heater.

Emerging biochemists more fully understand the flow of energy in ecosystems as they explore the laws of thermodynamics and relate them to energy transfer in food chains. They also investigate heat loss from the human body and how...

The carbon dioxide in our atmosphere and its effect on how heat is contained is summarized here. The flow of heat is explained with details about insulation and conduction. There are diagrams of heat circulation on a global level and...

A difficult-to-grasp concept, the fact that even cold objects contain heat energy, is the focus of this hot little video clip! Bill Nye tells physical science learners that heat is, by definition, the motion of molecules. He compares the...

Examine how heat can be transferred between systems by reconstructing a diagram on energy flow and solving problems on heat flow and work done.

Students explore energy and nutrient flow. In this science lesson, students diagram the flow of energy through food chains and food webs. Students discuss the importance of energy flow in Earth's ecosystems.

Have your class experiment with heat flow through materials. Learners conduct a heat flow experiment and chart their results. The lesson comes with all of the directions, templates, and other necessary materials.
