Erosion Lesson Plan

Instructor: Sharon Linde
Working with your students on soil and erosion? Use this Study.com lesson plan to explain what erosion is, teach the types of soils and erosion, and explain the effects of erosion. Examine how to prevent erosion, then follow up with a fun hands-on activity.

Learning Objectives

After this lesson, students will be able to:

  • list types of soil and erosion
  • define erosion
  • explain the effects of erosion
  • describe how to prevent erosion

Length:

1 hour

Materials

  • science journals or notebooks
  • picture of erosion
  • Skittles and M&M's
  • trays that can hold a small amount of water
  • eye droppers
  • water

Key Vocabulary

  • soil erosion
  • silt
  • sand
  • clay
  • wind erosion
  • bank erosion
  • sheet erosion
  • rill and gully erosion
  • strip farming
  • terraces

Curriculum Standards

  • CCSS.ELA-Literacy.RST.6-8.4

Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.

  • CCSS.ELA-Literacy.RST.6-8.3

Follow precisely a multistep procedure when carrying out experiments, taking measurements, or performing technical tasks.

  • CCSS.ELA-Literacy.RST.6-8.9

Compare and contrast the information gained from experiments, simulations, video, or multimedia sources with that gained from reading a text on the same topic.

Instructions

  • Show students a picture of a surface that has been eroded and ask them to do a 2W write - answering two W questions (who, what, where, when or why). Share answers and discuss.
  • Tell students they will be learning about erosion. Share background knowledge.
  • Before showing our video lesson, divide students into groups and assign key vocabulary words. Ask them to be in charge of recording the definition to share later.
  • Allow all students to take notes, if desired.
  • Show the video lesson Soil & Erosion: Definition, Types, Causes & Prevention.
  • Tell students to create an entry in their science journals titled 'Erosion'. Define terms, then create a chart to record the different types of erosion. Demonstrate on the board, if necessary.
  • Discuss:
    • Describe topsoil. What makes it susceptible to erosion?
    • How are the types of erosion the same and different?
    • What are some impacts of erosion? What makes them negative or positive?
    • What causes erosion?
  • Have students create a section in their journals titled 'Erosion Prevention'. List and discuss differing methods of preventing erosion. Ask:
    • Why is it in our best interest to prevent erosion?

Activity

  • Tell students they will participate in a demonstration of erosion using water, Skittles and M&M's.
  • Tell students to create and label a section in their science journals to prepare for the demonstration. Pose and record the guiding question 'How does erosion impact different types of soil?'
  • Tell students they will be dropping water onto Skittles and M&M's, each representing a different type of soil. Have students make predictions about which will erode first, and how many drops each will take to erode, and so on.
  • Conduct the experiment, recording data.
  • Have students write conclusions and share information. Compare results to hypothesizes and discuss. Ask:
    • What type of soil is most like the Skittle? M&M? Explain.
  • Allow students to eat a few Skittles and M&M's to show how cool you are.

Extensions

  • Visit a farm or invite a local farmer into your classroom to discuss methods used to prevent erosion.
  • Conduct longer-term experiments with the types of soil listed in this lesson to investigate erosion.
  • Research different methods of erosion protection practices used around the world. Ask students to present information to class, or make models of these methods.
