What is energy? Most of us have a feeling that we understand energy and recognize it when we see it, but coming up with a formal definition might be harder for us to do. In this section we introduce the concept of energy by having students investigate a variety of toys. They are given a list of the various categories and types of energy and are asked to form a working definition of what energy means. A series of videos and reading selections help them solidify their definition into an authoritative version.
