K.11 - Earth Resources: Reuse, Recycle and Conserve

The student will investigate and understand that humans use resources. Key ideas include

a)  some materials and objects can be used over and over again;

  • describe the difference between recycle and reuseBloom's Level:  Understand / Analyze
  • identify materials that can be reusedBloom's Level:  Knowledge

b)   materials can be recycled; and

  • give examples of objects that can be recycled  Bloom's Level: Understand

c)  choices we make impact the air, water, land, and living things.

  • explain  why recycling and reusing resources is good for the community.  Bloom's Level: Knowledge
  • communicate solutions that will reduce the impact of humans on the land, air, water, and or other living things in the local environment Bloom's Level:  Understand / Apply

BIG IDEAS

Natural resources make up the common objects and materials that we use.  These resources are limited and should be conserved.  Humans can impact the amount of these resources by reusing, recycling, and conserving.

UNDERSTANDING THE STANDARD

  • Natural resources such as water and energy should be conserved.
  • Recycling helps to save our natural resources. Recycling recovers used materials. Many materials can be recycled and used again, sometimes in different forms. Examples include newspapers that are turned into writing tablets.
  • Reusing materials means using them more than once. Examples include using dishes and utensils that are washed after use rather than using paper plates and plastic utensils and putting them in the trash.
  • Recycling, reusing, and conserving helps preserve resources for future use.
  • Resources will last longer if we recycle, reuse, and reduce consumption.


ESSENTIALS

Essential Questions

 How can materials an objects be reused?

 What objects can be recycled ?

 How can everyday materials be recycled?

 How can water and energy be conserved?

 Why do we recycle, reduce, and conserve resources?

 What would happened to our Earth if we did not reduce, reuse, and recycle?

In order to meet this standard, it is expected that students will

  • explain that recycling, reusing, and conserving helps preserve resources for future use.
  • give examples of objects, such as paper, cardboard, plastic containers, and glass containers, that can be recycled.
  • define reusing as using an object/item more than once.  Reusing materials reduces the amount of trash and conserves resources.
  • identify materials that can be reused (using dishes and utensils that are washed after use rather than using paper plates and plastic utensils and putting them in the trash)
  • describe the difference between recycle and reuse.
  • explain that resources last longer if we recycle, reuse, and reduce consumption
  • name ways to conserve water and energy.
  • describe how to properly dispose of a given material — paper, oil, aluminum, glass and plastics — by recycling.
  • explain that people can make choices to reduce their impacts on the land, water, air and other living things through recycling and reusing.

KEY VOCABULARY

aluminum - silvery, light metal used to make soda cans; can be recycled

conserve - to protect from harm or destruction

glass - a hard brittle substance, typically transparent; used to make windows, drink containers

natural resource - materials or substances such as minerals, forests, water and land that occur in nature

paper - produced from trees and can be recycled

plastic - a manmade material; containers/drink bottles are made from this material

preserve - to maintain something in its original state

recycle - to use again

reduce - to lessen the use of an object

reuse - to use more than once; using dishes that are washed rather than using paper plates
