Energy, Work and Power
Develop an understanding of the relationship between energy, work, and power. The video instructor explains the meaning of each and describes how they work together. He then provides an example that applies the formulas for both work and...
Bozeman Science
Momentum
Teach the basics of momentum through the video lesson. The instructor explains the concept of momentum, introduces the formula for momentum, and then demonstrates conservation of momentum. Problems include the momentum of multiple...

Thermoregulation
Hey, crank up the thermostat, my computer froze again! In a thermoregulation video, learners see how organisms either maintain their body temperatures or do not. The instructor explains the difference between conduction, convection,...
Bozeman Science
Osmoregulation
Because salmon live both in salt and freshwater, they have physical (different urine concentrations) and behavioral (drinking more or less water) adaptations to maintain osmolality. In this osmoregulation video, the instructor...

Fight or Flight Response
Harboring resentment against others is just as real to your body as a dangerous situation and can invoke a fight or flight response. The video explores the fight or flight response in humans. Viewers see what is happening inside the...
Bozeman Science
Homeostatic Loops
When someone is hot and their face is red, it is due to capillaries bringing blood closer to the surface of our skin so more heat can be lost. In the video, learners explore homeostasis and its role in the human body. Four homeostatic...
