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.
