This is part of the "Let's Explore Science" series for three- to six-year-olds. Each title helps to develop scientific awareness through simple experiments and projects that can be carried out safely in the home. The interactive text, written by education specialists in early learning, invites children to ask why and encourages them to come to their own discoveries and solutions and develop their own observation skills. There are special "guide to experiments" and "note to parents and teachers" pages.
