New! Shedding Light on Energy: Episode 2—Measuring Energy 35 min.

In this program, we introduce the “joule”, the unit for energy. We then look at how much energy is stored in different foods by comparing apples and oranges (normally a no-no) and we discuss how much energy we need to do certain things including nothing much at all. We then explore the concept of energy balance and reveal the two simple rules for weight loss. That’s right, there are only two!

New! Shedding Light on Energy: Episode 3—Energy Efficiency 31 min.

In this program, we introduce students to the concept of efficiency, which is a measure of how much useful energy you get out of something compared to the amount of energy that you put into it. We answer a bunch of questions including: How much light energy do we get out of light globes compared to the amount of electrical energy that goes into them? Hint: it’s not much; they should be called heat...
