As we try to achieve the National Science Education Standards (National Research Council, 1996) and promote general science literacy for young children, we might begin by discussing conservation or stewardship. Children can readily understand the idea of taking care of their own belongings as well as respecting what belongs to others. The leap then to taking care of planet Earth is not too difficult to make even in the primary grades. This activity relates to the Standards’ Content Standard F—Science in Personal and Social Perspectives: All students should develop an understanding of types of resources and changes in environments.
