Type: Lesson/Unit Plan

Overview:

Students learn about droughts and the link between climate change and water access through videos, readings, and discussions. They then brainstorm how to avoid a “Day Zero” in their watershed and how Mount Everest mountaineers can help protect the mountain's watershed. Students draw from their Project Journals to create and present a public education outreach campaign and supporting scientific arguments illustrating how humans impact water security. This lesson is part of the Peak Water: Mount Everest and Global Water Supply unit.

Content Standard(s):
Science
SC2015 (2015)
Grade: 6
Earth and Space Science
16 ) Implement scientific principles to design processes for monitoring and minimizing human impact on the environment (e.g., water usage, including withdrawal of water from streams and aquifers or construction of dams and levees; land usage, including urban development, agriculture, or removal of wetlands; pollution of air, water, and land).*


NAEP Framework
NAEP Statement::
E8.15a: Human activities, such as reducing the amount of forest cover, increasing the amount and variety of chemicals released into the atmosphere, and intensive farming, have changed Earth's land, oceans, and atmosphere.

NAEP Statement::
E8.15b: Studies of plant and animal populations have shown that such activities can reduce the number and variety of wild plants and animals and sometimes result in the extinction of species.

Knowledge:
Students know:
  • Human activities have significantly altered the environment, sometimes damaging or destroying natural habitats and causing the extinction of other species.
  • Changes to Earth's environments can have different positive and negative impacts for different living things.
  • Typically as human populations and per-capita consumption of natural resources increase, so do the negative impacts on Earth unless the activities and technologies involved are engineered otherwise.
  • Technology is anything man-made that solves a problem or fulfills a desire.
  • Technology can be an object, system, or process.
  • Engineering is a systematic and often iterative approach to designing objects, processes, and systems to meet human needs and wants.
  • The Engineering Design Process (EDP) is a series of steps engineers use to guide them as they solve problems.
  • The EDP may include the following cyclical steps: ask, imagine, plan, create, and improve.
  • Scientific information and principles regarding human impact on the environment must be used to design a process or solution that addresses the results of a particular human activity.
  • Scientific information and principles regarding human impact on the environment must be used to design a process or solution that incorporates technologies that can be used to monitor negative effects that human activities have on the environment.
  • Scientific information and principles regarding human impact on the environment must be used to design a process or solution that incorporates technologies that can be used to minimize negative effects that human activities have on the environment.
  • Causal and correlational relationships between the human activity and the negative environmental impact must be distinguished to facilitate the design of the process or solution.
  • Criteria and constraints for the solution must be defined and quantified to include individual or societal needs or desires and constraints imposed by economic conditions (e.g., costs of building and maintaining the solution).
  • Criteria are the principles or standards by which the process or solution is judged.
  • Constraints are the limitations or restrictions on the process or solution.
  • The process or solution must meet the criteria and constraints.
  • Limitations of the use of technologies exist.
Skills:
Students are able to:
  • Use scientific information and principles to generate a design solution for a problem related to human impact on the environment.
  • Identify relationships between the human activity and the negative environmental impact based on scientific principles.
  • Distinguish between causal and correlational relationships to facilitate the design of the solution.
  • Define and quantify, when appropriate, criteria and constraints for the solution.
  • Describe how well the solution meets the criteria and constraints, including monitoring or minimizing a human impact based on the causal relationships between relevant scientific principles about the processes that occur in, as well as among, Earth systems and the human impact on the environment.
  • Identify limitations of the use of technologies employed by the solution.
Understanding:
Students understand that:
  • A process or solution must meet criteria and constraints, including monitoring or minimizing a human impact based on the causal relationships between relevant scientific principles about the processes that occur in, as well as among, Earth systems and the human impact on the environment.
