Vicki Cobb has one several awards for her nonfiction science books. Why Doesn’t the Earth Fall Up? is another great one. Nine questions about motion are posed. Background information is given. Each chapter ends with a science experiment the children can do themselves which will provide the answer. Most of the materials are easy to obtain.
This book would make a great addition to a junior classroom studying motion. I think it would have benefited from a list of materials for each experiment. The reader has to skim through to find out what is needed.
Some of the experiments will produce surprising results, such as “Which takes longer, a big, high swing or small, low swing?” There are fun illustrations of children investigating.
The index at the back lists scientists mentioned in the text as well as bodies of space and scientific concepts.
