Description: Clever Calvin asks questions -- then goes out and finds the answers. Six humorously illustrated books take kids on tours and teach them a few things about modern technology. Here are the stories of how electricity is generated and brought to our homes, how oil is pumped from the ground to become many different products, how paper is made, and how water is collected and purified -- then brought to our kitchens, bathrooms and swimming pools. Two additional new volumes deal with paleontology (dinosaurs!) and ecological concerns in terms that will appeal to kids. Each Clever Calvin book features a glossary of science terms and suggestions for safe experiments children can perform.
