3.8 - Earth Resources: Human Influence

The student will investigate and understand that natural events and human influence ecosystems. Key ideas include

a)  human activity affects the quality of air, water, and habitats;

  • analyze the effects of human influences on the quality of air, water, and habitats.  Bloom's Level:  Analyze
  • explain how conservation efforts can reduce the negative impacts of human activity on a habitatBloom's Level: Understand
  • propose a solution or design a device that will reduce the impact of a human activity or a natural event on an ecosystem. Bloom's Level: Create

b)  water is limited and needs to be conserved;

  • research, explain,  and communicate  methods of water conservation to be used in both homes and schools. Bloom's Level:  Understand 
  • observe water use in the school setting and  identify possible water conservation solutions. Bloom's Level: Understand
  • collaboratively design  and implement a plan to conserve water at home or at school.   Bloom's Level: Analyze / Create

c)  fire, flood, disease, and erosion affect ecosystems; and

  • propose a solution or design a device that will reduce the impact of a human activity or a natural event on an ecosystemBloom's Level: Create

d)  soil is a natural resource and should conserved.

  • observe and provide evidence of soil erosion around the schoolyard/community.   Bloom's Level: Understand / Apply
  • create and implement a plan to reduce erosion.   Bloom's Level: Understand

BIG IDEAS

Humans behaviors and natural disasters can negatively impact organisms and their habitats.  Conservation practices can lessen the effects of human activity and natural disasters upon the environment.


UNDERSTANDING THE STANDARD

  • A variety of factors can impact an ecosystem:  human actions, may reduce the effects of these factors on an ecosystem.
  • Human actions include polluting, clearing large plots of land to build neighborhoods or plant crops, over-fertilizing lawns, burning fossil fuels.
  • Human actions can negatively affect the survival of organisms in an ecosystem.
  • Humans can make choices that reduce their impact on an environment.
  • The water supply on Earth is limited.
  • Pollution reduces the amount of usable water; therefore, the supply should be conserved carefully.
  • Natural occurrences include: earthquakes, forest fires, tornadoes, hurricanes, floods, coastal erosion, disease, and can harm the environment.
  • Humans cannot eliminate natural occurrences, but they can take steps to reduce their impact.
  • Mitigation measures such as adoption of zoning, land-use practices, and building codes can prevent or reduce damage.
  • Conservation is the careful use and preservation of natural resources.  
  • Humans need to help conserve limited resources.
  • Since soil takes a long time to form, it should be conserved not wasted.


ESSENTIALS

Essential Questions:

·  How do natural events impact the survival or death of plants and animals?

·  How can human action impact the survival of plants and animals?

·  How can we conserve natural resources?


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

  • analyze the effects human influences on the quality of air, water, and habitats.
  • analyze the effects of fire, flood, disease, and erosion on organisms and habitats.
  • describe how conservation practices can affect the survival of a species.
  • describe a conservation practice in the local community.
  • propose a solution that will reduce the impact of a human activity or natural event.
  • identify water conservation solutions after observing how water is used
  • provide evidence of soil erosion
  • create and implement a plan to reduce erosion
