Subjects: Biology

The 3-part Shedding Light on Energy series allows teachers to teach the topic of energy really easily without actually using much energy! With a perfect mix of biology, chemistry, and physics, we explore every aspect of energy including what it is and how we measure it.

The three programs in the series brilliantly cover:

• the many different forms of energy;
• energy transformations (it’s like magic, but better);
• where the energy in our food comes from;
• the amount of time a single kilogram of fat can fuel us for (we’re talking days!);
• the unit for energy, the joule;
• power and the watt (the what? Yes, the watt);
• the energy content of different foods (and how it’s measured);
• the energy expenditure of the human body (and how it’s measured);
• energy balance (and how it can go wrong);
• the two simple rules for weight loss (that’s right, there are only two!);
• where the fat actually goes when people lose weight;
• efficiency (there’s never been a more efficient way of learning about it);
• why LED globes have taken over from incandescents (and why it took so long even though LEDs have been around since the 1960s);
• how the arches of our feet help us to chase down horses (yes, you read that correctly!)
• and much more!
