Natural science looks at things in the material words such as plants, animals and earth. Books are a wonderful springboard in the development of life long interests. Many of the science books available begin from preschool and kindergarten age and encourage the discovery and exploration of birds, animals, plants and the sky. These books give children a peep into how Ecosystems survive and depend on each other and are an excellent resource for teachers. Children are able to enter a world otherwise beyond their reach.
