This series uses cartoon style illustrations and humorous narrative text to make key topics in Science and Geography both accessible and engaging. This approach encourages children to read about and understand complex ideas. This story follows the passage of a water droplet, from the time when it evaporates from the ocean and becomes the water vapour that makes up clouds to the moment it falls as rain. We learn how water is cleaned and used before being returned once again to this never-ending cycle. This book also contains an experiment, more great facts to know, useful websites and an index.
