Paul Andersen explains how energy is conserved within a system. In both macroscopic and microscopic collisions the amount of energy before the collision is equal to the amount after. He then defines heat as energy transfer between objects with different temperatures. He explains how heat is transferred via conduction, convection and radiation. A teaching progression K-12 is also included.
In this video Paul Andersen explains how matter and energy flow and cycle through systems. He starts by explaining how energy and matter input and output will always be conserved. He addresses the many misconceptions surround energy and matter including the belief that food contains energy. He explains how nuclear reactions conserve both batter and energy. The video ends with a teaching progression for grades K-12.
This video uses cooking to illustrate the difference between conduction, convention, and radiation. After viewing the quiz, learners can test out their knowledge on the Heat:Science Lesson quiz.
