Continuum of Activities

Continuum of Activities

The list below represents a continuum of activities: resources categorized by Standard/Eligible Content that teachers may use to move students toward proficiency. Using LEA curriculum and available materials and resources, teachers can customize the activity statements/questions for classroom use.

This continuum of activities offers:

  • Instructional activities designed to be integrated into planned lessons
  • Questions/activities that grow in complexity
  • Opportunities for differentiation for each student’s level of performance

Activities

  1. Define weathering.
  1. Define erosion.
  1. Weathering and erosion are both ways the earth is slowing changing.  Identify one natural event that may change the earth’s surface quickly.
  1. Predict how ice can affect the Earth’s surface.                                              
  1. Compare and contrast wind and water erosion.
  1. Hypothesize whether or not living things can cause erosion.

 

Answer Key/Rubric

  1. Weathering is when rocks are broken down into smaller pieces.
  1. Erosion is defined as the process of which something is worn away.
  1. Acceptable responses may including, but are not limited to:
  • Earthquake
  • Mud/land slide
  • Volcano eruption
  • Tsunami
  1. Acceptable responses may include, but are not limited to:
  • Water can get into cracks in rocks and turn into ice.
  • As water freezes it expands.
  • As the ice gets bigger, it will force the crack to get larger and could eventually dislodge part of the rock
  1. Acceptable responses may include, but are not limited to:
  • Both wind and water erosion change the surface of the Earth.
  • Wind erosion happens in drier climates when the wind picks particles up.
  • Wind can erode hills and mountains by wearing away at the surface
  • Water erosion can happen from rivers, lakes, and oceans or from flooding.
  • Water can wear away at the surfaces, and carry these particles to make different landforms.
  1. Acceptable responses may include, but are not limited to:
  • Living things can cause erosion.
  • Plants roots can break apart soil and rocks.
  • Insects move soil around.
  • Animals with claws can move soil around.
