People of all ages learn to scuba dive for many reasons. For instance, they may want to see amazing habitats, swim with beautiful marine life, or explore shipwrecks on the ocean floor. Scuba takes a look at the history of diving: the equipment, how to get certified as a scuba diver, and the effects caused by diving. The book can also be used to teach students how to identify cause-and-effect relationships as well as to use past-tense verbs.
