Learn all about dams (manmade and otherwise) in Engineering Super Structures: Dams. Dams hold back water, which creates lakes. People have been making dams for a long time. Beavers also build dams to make ponds. This water held back by dams is used to water crops and create electricity.

This book has good pictures of actual dams. Some pictures, such as those of the interior of dams that generate electricity, may be confusing since their purpose and interaction with the water isn't obvious. The text consists of short, simple sentences. The vocabulary of the book is more advanced than the sentence structure, which feels off balance. There is a glossary for many of the words in the back of the book. However, considering how simple the sentences are, averaging around four words, an explanation within the text seems necessary. Additionally, while the sentences themselves are easy to read, they are not as easily understood. How the water is used to water crops, and especially the most basic concept in the book, how dams hold back water, seem to be skipped over.
