註釋Genuine scientists test their theories through experiments, using the results to uncover truly amazing discoveries. In this beneficial STEM-based book, readers are the scientists diving into experiments about forces such as gravity, friction, and magnetism. They’ll use easy-to-find materials such as balloons, erasers, and rulers to perform step-by-step experiments, learning more about forces at work in the world all around them. A summary of each carefully illustrated experiment reviews what the result conveys about the concept, while extra activities encourage more experimentation, an attribute of every great scientist!
