The Wheel on the School by Meindert DeJong. Living things depend on natural resources-air, water, soil, sunlight, minerals, plants, and animals. Students use reference materials to define and make a list of natural resources. They classify these into seven categories. Each group of students designs an advertisement for a specific natural resource.
Students write letters to local organizations associated with specific natural resources.
Students begin inferring some relationships that might exist among natural resources. Students describe how they use natural resources in their everyday lives. They complete a chart to identify the natural resources used to make various items in the classroom. Students observe human-made objects outdoors and classify them according to the natural resources used to make them. They also observe and classify objects from nature.
