Essential Understanding

The student knows that the natural world includes Earth materials.

Science Background

Natural Resource: Wikipedia (website) – Every manmade product came from natural resources (materials found within the environment). Learn about different kinds of resources, their uses and protections.

Signature Lesson

Is It Natural or Transformed?: BioEd Online (Website) - The class will examine, sort, distinguish and discuss natural and processed materials. Teacher background included.

Supporting Lessons

Developing an Object or Tool: BioEd Online (Website) - Student teams work together to establish the process through which a natural resource (e.g., a tree) becomes a finished product (e.g., a wooden chair). Teacher background included.

Our Natural Resources: Minnesota Office of Environmental Assistance (PDF) – Natural resources are the raw materials supplies by nature. Students learn to distinguish natural resources, such as petroleum, from manmade items, such as plastic.

Elaboration Lessons and Extensions

Natural Resources on Earth: NASA (PDF) – Lesson introduces students to the natural resources that help us live and allow plants to grow.

Where Did that Pencil Come From? Econedlink.org (website) - Students determine what goods can be produced using natural resources, identify which natural resources contribute to the production of a particular item, and identify natural resources on a map.

Assessment Ideas

Once students have investigated the natural and manmade materials in the Signature Lesson (see above), allow them to select one example of each. Have students work with partners to come up with two new uses for each material chosen. Students should record their ideas in a science journal, using words and pictures to show two uses of the objects.
