The Science of a Spring (Science World (Raintree))

From School Library Journal Grade 2-5-These series entries offer basic information with supporting activities. The clear, factual explanations are presented with simple text, boxed facts, and clearly captioned color photographs and drawings. The look is glossy and appealing. The first title discusses how several common simple machines work, including a stapler and a lock. The second volume explains where sound comes from, how it travels, how we hear it, and how we change it. Andrew Haslam's Make It Work: Sound (Thomson Learning, 1992; o.p.) covers roughly the same topics in greater depth and with more detailed experiments. Still, these are worthy additions for collections in need of easy science books.
