How Do You Turn Nuclear Energy Into Electricity?
Nuclear energy creates electricity through fuel rods that are
placed into a moderator to produce heat that is taken out by a heat
exchanger. Discover how nuclear reactors are basically used to create heat with information from a science teacher in this video.
How Things Work : How Nuclear Energy Works
Nuclear energy works in much the same way as traditional energy, except it requires less fuel to work and has harmful byproducts. Discover how nuclear energy works from a math and science teacher, Steve Jones.

Where Do You Get Your Energy
Cells extract energy from sugar to produce ATP, the molecular fuel that powers all life processes. This interactive activity adapted from the Exploratorium delves into the processes that enable cells to unlock the energy contained in the foods we consume. We often use the term "energy" as an informal shorthand for our ability to stay alert and complete tasks. In fact, the presence of energy-rich molecules and our cells' ability to obtain, process, and use this energy is critical to life.
