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 reuse. Bloom's Level: Understand / Analyze
- identify materials that can be reused. Bloom'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
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
- 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
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.
aluminum - silvery, light metal used to make soda cans; can be recycled
conserve - to protect from harm or destruction
energy - power to do work
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
