Book excerpt: Water Science provides opportunities for students to discover for themselves the wonder of water (it covers three-fourths of the Earth's surface, it is a part of all living things, it is the only substance on Earth that exists in three forms, it dissolves, it evaporates, it has a skin and much more). Your students will enjoy conducting a variety of experiments with water, solving challenges, competing with one another in simple games and taking quizzes to review what they have learned.
