Thermal Energy TV


EI TV - Educational Innovations BlogThermal energy—the energy that is generated and measured by heat—is such a wonderful topic that can be approached in many ways.  So many questions to explore!  What is heat?  How does heat travel?  What’s the difference between heat and temperature?  How do we measure temperature?  What are conductors?  Insulators?  And on and on…

There are times when a video offers the easiest, most accessible way to explain a concept.  This is certainly true when it comes to thermal energy.  Feel free to share this collection of videos with your students!   If you find a video on thermal energy that you think deserves to be added here, please let us know in the Comments section below.
