This publication, the second in a series of seven for elementary schools, is an environmental education curriculum guide with a focus on waste management issues. It presents a unit of exercises selected for first grade students to introduce the ideas that both natural and man-made objects have uses in the world, and the objects which are not useful are classified as waste objects. Litter is cited as one problem that very young children can comprehend and solve. They can learn to dispose of waste properly, help recycle some items, and come to understand how their own behavior affects the environment. The activities included in this unit nurture a first step in building a sense of environmental awareness and responsibility. The unit discusses the following major ideas: (1) natural and man-made objects exist and have uses in the world; (2) objects in our environment can be classified into useful and waste objects; (3) litter is man-made or man-used solid waste that is in the wrong place; (4) people are responsible for disposing of waste properly; (5) some objects last a long time and others change or disappear quickly; and (6) some waste objects can be reused or recycled. Each activity in the unit meets the Virginia Department of Education Standards of Learning Objectives for Science; however, the material is designed to be interdisciplinary and may also be used to meet social studies, health, language arts, mathematics, or art requirements. A list of additional resources (articles, magazines, educational curricula) is included. (MCO)
