For example, Electricity discusses the different types of energy that create the phenomenon and describes how to make a simple circuit, or how to use static to attract pieces of paper to a comb. Light and Dark , one of the strongest books in the set, explains the role light plays in sight, day and night, and color. Kids can make a sundial using a paper plate, clay, and a straw. Materials is most appropriate for kindergartners and includes experiments that test the hardness of items and whether they sink or float. Pushes and Pulls is a great introduction to physics basics such as gravity, pressure, and friction. Featuring many color photographs, some cartoonlike illustrations, and a large font, this series is a first choice.
