"Nine projects per book illustrate STEAM concepts and offer practice with observation, prediction, and testing.Great process photos are clearly numbered to correspond to concise written instructions--although projects that are more complex are sometimes lacking in guidance. The 'Simple Machine Board Game' project in Crayola ® Rainy-Day STEAM Activities asks readers to, 'Design a board game using as many simple machines as you can.' Sidebar 'takeaways' help explain the concepts demonstrated. Emphasis on recycled and on-hand materials makes these projects easy to try. Although these branded books are clearly meant to show crafters what they can do with Crayola products, the projects work just as well with supplies from other manufacturers. There are many options for making each project one's own, and a 'Maker Remix!' that builds on a project in the book, offering next steps, variations, or new uses of the materials created. VERDICT Lots of projects, with instructions that might require some adult interpretation.
