Two new Start with Science books introduce kids to core science concepts through engaging stories, fresh illustrations, and supplemental activities. One day Oscar comes across a nest made of twigs and leaves, perfect for sheltering eggs. It makes him wonder about all the things we use like glass, paper, plastic, and cloth. With the help of his friend Snail, the curious kitten learns why we choose specific materials to do different jobs, where the materials come from, and what useful qualities they have.
