PICTURING THE EFFECTS OF EROSION

4.7B Earth Science Engage

• Identify and observe effects of events that require time to happen.

• This includes erosion, weathering, and dissolving.

Students need to:

Gather the Materials

Mountain cards (see template) Crayons or markers Construction paper Scissors Tape or glue

Explain the Scenario to Students We will have a birds eye view today,

seeing how mountains can change.

Identify the Forces…

Wind, water, and ice can erode mountains, and we need to show how each of these can change the mountain.

Hand out the cards

What will the mountains look like next?

Have students draw what could happen.

Brainstorm the changes…

Wind Water Ice

These forces can change the mountain. Have students think of what the changes might look like. Students will then create pictures of those forces affecting the mountain.

Encourage multiple responses! Be sure students have supportive

reasoning for why their mountain looks the way they claim! Remind students there are many correct

answers, as there are many ways these forces change landforms in nature.

Share ideas with students

For example, students may decide that wind would only erode one side of the mountain, or only near the peak.

They may decide ice would gouge out the valley or shatter surface rocks leading to erosion.

Students can also draw a stream on a mountain and show a valley forming from water erosion or a rounding of the mountain’s features from rain.
