Publisher's Synopsis
Walter, a warthog, sees water everywhere: in the bathtub, from the garden hose, from the sky as rain. He writes down everything he notices about water in a special blue notebook. And then he shares what he learns with his friend Willa. As Walter and Willa do some science experiments, they find out cool things about water: water evaporates, ice floats, water can bring a dying plant back to life, and more. Tag along with Walter and Willa in this fun introduction to one of Earth's most important resources. Simple experiments you can do at home and a page full of fascinating facts about water are included.
