This book has a lot of information about volcanoes. The information includes the history of the volcanoes, how volcanoes erupt, and what toll they take on the people around them. It starts with the science of a volcano and what cause it to erupt. It talks about the science vocabulary including magma, platelets, and lava. It then goes on to talk about the big erupting volcanoes throughout history. It also talks about how an island of Hawaii came to be because of an erupting volcano. After it talks about history it proceeds to tell about all the lives that have been lost because of erupting volcanoes. I am not very interested in volcanoes. However, I did enjoy learning more about them from this book. It does a great a job of informing the reader about volcanoes in a way that is not overwhelming. A classroom extension could be to have students draw a picture of a volcano erupting. Another extension could be to have students create a volcano altogether as a class that will erupt.
