Watersheds, the Water Cycle and Us

Learning Experience 2

Big Idea

How land and water interact with the natural water cycle is key to understanding the answer to the question “What is a Watershed?”

Summary

Becoming stewards of our watershed requires an understanding of how it operates and how human activities impact it.

Engage

Students will go on a scavenger hunt around their school or community to identify how water cycles through their watershed.

Explore and Explain

Activity 1:

In this activity, students identify the parts of a watershed on a diagram.

Activity 2:

In this activity, students build a model watershed to visually represent how water moves on land.

Elaborate

Students will use the interactive website Model My Watershed to draw the parameters of their own watershed and identify some of its characteristics.

Teacher Support

Essential Question:
What actions can we do to protect our land and water?

Guiding Questions:

What is a watershed?
How does the water cycle work in the watershed?
What are natural watersheds made of?
What watersheds are we in?

Students will be able to:

Explore and Explain

  • identify and list the characteristics of their watershed such as human
    made structures, roads, sidewalks, parking lots, as well as natural parts of
    the watershed such as parkland, trees, etc.
  • describe a system (e.g.,watershed) as a group of related parts with
    specific roles that work together to achieve an observed result.
  • describe how scientists use models to explore relationships in natural
    systems (e.g., an ecosystem, river system, the solar system).
  • review a video, analyze a graphic, and build models in order to compare
    and contrast natural and urban watersheds.

Elaborate

  • understand maps and where key points are located
  • draw the parameters of their bio-region (watershed) and/or community,
  • identify and list the characteristics of their watershed
  • describe how scientists use models to explore relationships in natural
    systems (e.g., an ecosystem, river system, the solar system).

Each group of 2 to 4 students needs these materials:
Aluminum roasting pan
Newspaper, brown bags, or other material that can be crumbled
Masking Tape
Sheet of white plastic, slightly larger than the pan (a kitchen
trash bag cut into single sheet works)
Spray bottle
Blue food coloring (optional)
Paper towels for clean up
A thick book

Watershed noun
an area of land that drains water into a specific waterbody

Headwaters noun
the source of a moving body of water like a river or stream

River noun
a large natural stream of water flowing in a channel to the sea, a lake or another such stream

Tributary noun
a stream or river that flows into and joins a main river

Vegetation noun
plant life

Runoff noun
the excess water that flows over land when the soil below cannot absorb any more water

Precipitation noun
water that falls to the earth as hail, mist, rain, sleet, or snow

Land Cover noun
indicates the physical land type such as forest, grassland, wetland or open water

Terrain noun
the physical features of a tract of land

Climate noun
the long-term pattern of weather in a particular area

Infiltration noun
the process by which precipitation or water soaks into soils

Using the  Activities and the Mapping my Watershed Worksheet, students will be able to describe a system (e.g.,watershed) as a group of related parts with specific roles that work together to achieve an observed result.

 Compare and contrast how water behaves in natural and urban watersheds

List some characteristics in order to draw the parameters of your local watershed.

Identify the characteristics of your watershed and make a case for why it is important to be able to so.

Describe how scientists use models to explore relationships in natural systems (e.g., an ecosystem, river system, the solar system).
