Dr. Forrester talks about thermal energy. She defines thermodynamics and talks about conduction, convection, and radiation. She also defines photovoltaic energy. She talks about solar power and then shows how to make a solar oven.

This video explores five fun facts about heat transfer.

In this video we learn how three phase electricity works from the basics. We explain how three phase electricity is generated, how the voltages vary, how to calculate the voltages and vrms, what frequency, hertz and cycle mean and how...

Temperature sensors explained. How do temperature sensors work? In this video we learn the basics of how different temperature sensors work. We look at thermometers, thermocouples, thermistors and resistance temperature detectors RTD.<br/>

Conduction and Convection examines convection and conduction by defining and exploring scenarios in which each occurs.

An igloo is made of compressed snow. Compact hardened snow is a great insulator of heat because snow is nothing but semi-frozen water with roughly 95% trapped air. The air molecules trapped between the tiny ice crystals create air...

In this video, we discuss how the electrical conduction system generates a pacemaker potential by viewing the action potential diagram.

Lasers aren't just for sci-fi fans. We use them to scan barcodes in shopping malls, conduct surgeries, even remove tattoos! All thanks to the very first, the Ruby Laser.

This live-action video program is about cryosphere. The program is designed to reinforce and support a student's comprehension and retention of the term through use of video footage, photographs, diagrams and colorful, animated graphics...
