Work, Power, and Entropy
Students experience work and power and observe the process of entropy. For this physics lesson, students conduct an experiment that shows work (force & distance), power (work/time), and exemplifies the process of entropy.

Proof: S (or Entropy) is a valid state variable
Proving that Entropy is a valid state variable is the focus of this chemistry video. Sal takes students back to his diagrams used to illustrate the Carnot Cycle, and uses those diagrams to prove that the state (A) which was used on the...

Energy and Work: Transformation through Engines
Young scholars are introduced to the concept of thermodynamics. In groups, they participate in experiments in which they discover how potential energy converts into kinetic energy. They use the internet to research the components of a...

Energy and Work: Transformation Through Engines
Students conduct a webquest on an energy source they chose. In this physics lesson, students design an experiment to determine the factors affecting potential and kinetic energy. They calculate speed and create distance vs. time graphs.

What Triggers a Chemical Reaction?
Chemical reactions are happening all around us every second of every day, but what exactly causes these changes to occur? Using easy-to-understand analogies, this video explains how the concepts of enthalpy and entropy determine the ways...
