Science
Strand V
Use Scientific Knowledge from the Earth and Space Sciences in Real-World Contexts

 

Science/Strand V
Content Standard 1
All students will describe the Earth’s surface; describe and explain how the Earth’s features change over time; and analyze effects of technology on the Earth’s surface and resources. (Geosphere)

 

Science/Strand V/Content Standard 1
High School

 

Science/Strand V/Content Standard 1/High School
Benchmark 3
Explain how common objects are made from Earth materials and why Earth materials are conserved and recycled.

Benchmark Clarification

Everything people make involves materials we have mined from the Earth. If people’s livelihoods are dependent on the extraction of materials.(e.g., iron/copper mining in the UP and other ores in other parts of the world) then severe social and economic impacts are likely when these materials are depleted.

Students will:

  • Investigate Earth’s natural resources, how they are used, and how they are limited
  • Deduce the impacts when resources are depleted
  • Explain how an individual’s decisions involving consumption can have both a local and global impact

Real World Context
Manufacturing processes

Steel mills

Auto assembly lines

Paper making

Local recycling center for materials like

  • glass
  • plastic
  • aluminum
  • steel cans
  • motor oil

Examples of technical and social means for slowing the depletion of Earth’s resources such as developing more fuel-efficient cars, mandating their use; curbside recycling, tax on the use of fossil fuels, disposal in landfills and incinerators.

Instructional Example

Benchmark Question: How do we make things we use every day?

Focus Question: How is a common household or classroom object made? Include materials, processes, energy, and possible methods of recycling or conservation.

Each student will choose an object found in the classroom or the home. Students will do research using books, their local recycling center, local businesses, educational television, and/or videos to determine how their object is made. Students will report their work in an oral, written, or visual (multimedia) format.

Constructing: (SCI.I.1.HS.4), (SCI.I.1.HS.5).

Reflecting: (SCI.II.1HS.3), (SCI.II.1.HS.6).

 

Science/Strand V/Content Standard 1/High School/Benchmark 3
Assessment Example

Each student will create a written, oral, visual, or multimedia presentation including the following information:

  1. How the chosen object is made from Earth materials
  2. How the material is conserved and/or recycled
  3. Location of mines
  4. Chemical composition of resource
  5. Physical form of ore (color, density of ore, and texture)

(Give students rubric before activity.)
