The Science at Work series gives pint-size readers their first glimpse of the different ways science functions in the world around them, with this volume tackling magnetism. Each page is adorned with one to two short sentences and a color photo illustration, most often a magnet attracting or repelling something or an object utilizing magnetism, such as a compass or crane. Introducing science concepts to elementary-school readers is a challenge, and this book does so with mixed success. While offering many examples of where magnetism operates, it's not always clear how it works. For instance, readers learn that a magnet helps keep a refrigerator's door closed, but not how TVs use magnetism, only that they do. Best as a supplement to more detailed texts or as an activity prompt.
