Energy Transfer and Efficiency

Published on August 28, 2022 by

When we turn on a light bulb, not all of the electrical energy is converted to light, but some energy is wasted as heat. This brings us to the concept of efficiency in an energy transfer. In this video students will be introduced to efficiency, Sankey diagrams, and how to calculate efficiency.

The video satisfies the 4-PS3-4 requirement of fourth-grade science proficiency.

Students who demonstrate understanding can: 4-PS3-4. Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.
