Most people never consider what is happening in the ground beneath their feet, but in reality there is a tremendous amount of science going on deep in the earth. Twenty-five hands-on experiments focus on the movement of tectonic plates, the formation of volcanoes, potential seismic energy, and the very real threat of earthquakes. Readers can generate potential energy, make their own edible volcano model, or chart fault lines around the globe. Essential questions introduce each chapter and set a contextual purpose for reading. Real-life events, relevant terms, and fun facts accompany each project, while very detailed scientific explanations are offered to guide budding scientists' observations. Scannable QR codes and keyword search suggestions offer easy access to electronic primary sources about the scientists and discoveries that have added to the field of seismography. This multidisciplinary STEM resource appeals to multiple modalities and learning styles and covers more obscure topics in physical geography and science.

Reilly provides a detailed examination of the movements of tectonic plates, and the effects of those movements, in this addition to the Built It Yourself series. Throughout, Reilly poses relevant questions (-Are there any benefits to earthquakes? Do they serve a valuable purpose for our planet?-), discusses scientists- hypotheses about Earth, and invites readers to get involved via 25 activities, which include cooking molten rock candy, making a cardboard box seismograph, and creating a Jackson Pollack-style painting of an erupting volcano. Thompson-s cartoon spot illustrations break up the book-s substantial text. It-s a solid starting point for readers interested in Earth-s geology. Ages 9-12. (Jan.)
