PreS-Gr 1—Simple, straightforward text accompanies colorful full-page photos in these concise volumes that introduce readers to the science of physical transformation. Distilling the multistep processes to their most basic components, each book begins with a declarative statement, such as "Ice cream is made from milk," then guides students through each stage of change. The choice of topics works well for a young audience, since most readers use or consume the products in their daily lives, lending the series relevance. Those interested in learning more about these transformations and their end results are provided with books and websites for further exploration in "Find Out More." Good choices to round out science collections for younger readers.
