Dr. Forrester talks about thermal energy. She defines thermodynamics and talks about conduction, convection, and radiation. She also defines photovoltaic energy. She talks about solar power and then shows how to make a solar oven.

Learn about the energy stored in a capacitor. Derive the equation and explore the work needed to charge a capacitor.

This video explores the science behind capacitors, including what they are, how they work, and how they store electric potential energy in an electric field. The definition of capacitance is given, as well as the units and symbols used...

Movement of a Thermometer investigates heat as a form of energy by conducting an experiment that involves placing a mercury thermometer in hot water and observing the mercury expand or “rise.”

This video offers a more in depth look at how nuclear fusion occurs in the Sun.

Energy from the Sun describes how life on Earth depends upon energy from the sun by providing examples of dependence.

Conservation of Energy examines the idea that energy cannot be created or destroyed but can be converted from one form to another by exploring conservation of energy.

Chemical Reaction in a Bag demonstrates that energy has the ability to cause motion by conducting an experiment that involves adding vinegar to baking soda in a zippered sandwich bag.
