Teach Engineering: Human Power
Students do work by lifting a known mass over a period of time. The mass and measured distance and time is used to calculate force, work, energy and power in metric units. The students' power is then compared to horse power and the power...
Physics Aviary
Physics Aviary: Mechanical Equivalent of Heat Lab
This lab is designed to have students look at a greatly simplified version of James Joule's experiment showing the conversion of mechanical energy to heat.

Pbs Nova: The Power of Tiny Things
Have you ever wondered what would happen if you converted the mass of a paper clip into an amount of energy? In this informative quiz, discover the answer, and explore other examples of mass-energy equivalence.
TED Talks
Ted: Ted Ed: How Does Work, Work?
In this video, Peter Bohacek explains the interplay between work and power and how it can be seen in the functioning of a clock. [4:31] Followed by a short quiz and a list of additional resources to explore.
