Check out STEM (Science, Technology, Engineering, and Mathematics) Friday at Chapter Book of the Day
and Wrapped In Foil.

One of the things that I ask students to notice when reading informational text is how the author chooses to present their material. In How Do Waves Form?, author Wil Mara skillfully takes us to the very beginning of a wave where energy from the wind goes into the water to start the process. From there he goes step by step showing the reader how a wave builds its strength with the variables of wind speed, wind size, and length of wind gusts. Particularly effective are his use of common items like birthday candles and balloons to illustrate different facets of the life of a wave. The last chapter of the book is about types of waves with an informative diagram illustrating the formation of a tsunami.

If you have a unit on beaches and/or oceans, How Do Waves Form? would be a welcome addition to your collection. You could easily teach a lesson on sequence showing the steps of how a wave forms. This book could also be helpful in a unit on force and motion.


  1. What a perfect book for summer. I will definitely be on the look out for this one.

  2. You're right about that. Thanks for stopping by, Roberta!
