Benchmark 6
Demonstrate ways to conserve natural resources and reduce pollution through reduction, reuse, and recycling of manufactured materials.

Benchmark Clarification

Manufactured materials can be reduced, reused, and recycled to conserve natural resources.

Students will:

  • Investigate ways to conserve natural resources
  • Reduce pollution through reduction, reuse, and recycling of manufactured materials

Key Concept
Materials that can be recycled:

  • paper
  • metal
  • glass
  • plastic

Conservation and anti-pollution activities:

  • reduce
  • reuse
  • recycle

Real World Context

  • collections of recyclable materials
  • plan for recycling at home and school
  • composting
  • ways of reusing or reducing the use of paper

Instructional Example

Benchmark Question: What effects has technology had on the EarthÕs surface and resources?

Focus Question: What can be done with school trash to conserve natural resources?

The teacher will pose the focus question to facilitate discussion and then will review how natural resources are used to produce the products we use in our lives on a daily basis.

The teacher will present students with a container of trash. The trash should be poured from the container onto a mat. Students will wear latex gloves and sort the trash into piles of recyclable materials and non-recyclable materials. Students will discuss questions such as:

  • What can we do to recycle these objects more effectively at school?
  • What happens to these items when they reach the dump (or landfill)?
  • How does this waste affect the environment?



NOTE: Students might think that all plastics and papers are recyclable. It isnÕt too early to educate students on what types of plastics (#2 HDPE) and paper are able to be recycled locally. Local recycle center coordinators are usually happy to visit the classroom and/or provide educational materials.

  • What natural resources are conserved by reducing, reusing, and/or recycling these materials?
  • What technology is used to recycle these materials?
  • Who was instrumental in studying the relationship between deterioration of the planet and industrial growth and waste? Warren Washington.

Assessment Example

Small groups of students will design a plan to reduce, reuse, or recycle a waste product from school. They will estimate the volume/weight of the natural resources that will be conserved by this plan.

(Give students rubric before activity.)
