Strand V
Use Scientific Knowledge from the Earth and Space Sciences in Real-World Contexts

 

Science/Strand V
Content Standard 2
All students will describe the characteristics of water and demonstrate where water is found on Earth; describe how water moves; and analyze the interaction of human activities with the hydrosphere. (Hydrosphere)

Science/Strand V/Content Standard 2/Elementary
Benchmark 2
Trace the path that rainwater follows after it falls.

Benchmark Clarification

After rainwater falls, it follows a downward path to a water body.

Examples of water paths:

  • gutters
  • playground
  • drains
  • streams
  • wetlands

Students will:

  • Illustrate the path that rainwater follows to a water body

Note: This is not the water cycle.

This benchmark can be related to the concept of a watershed, streamshed, or creekshed.

  • to rivers
  • into the ground

See Precipitation (SCI.V.3.E.1).

Bodies of water

  • streams
  • rivers
  • lakes
  • oceans

Instructional Example

Benchmark Question: How does water move?

Focus Question: Which way does water flow?

Students will work in groups to determine that water flows downhill. The teacher will ask students about their visits to lakes or rivers and what they have observed about the movement of the water. The teacher then will pose the focus question and set up the following model of a river (See River Model Diagram below).

  • Cut one piece of aluminum foil 24 long.
  • Fold it in fourths to make a trough.
  • Cut a V-shaped notch out of the top of the Styrofoam cup, fill the cup with water, and add two to four drops of food coloring.
  • Put the cup on the table and cradle the aluminum foil trough in the V in the cup. This allows one end of the trough to be elevated.
  • Have the other end extend just over the edge of the table.
  • Place a bucket under the lower end of the trough.
  • Fill a spray bottle about halfway with water.

The teacher will ask students to spray different parts of the model and observe where the water flows. Students will explain how the water flowed on the model. During discussion, be sure to include how water flows down hillsides or slopes. The teacher will ask students what each part of the model represents: cup = mountain, trough = river, bucket = lake, spray = rain.

Reflecting: (SCI.II.1E.2).
