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. List 2 patterns that you can observe in nature.

  2. List 2 human-made patterns.

  3. Summarize the pattern that occurs during an average star’s lifecycle.

  4. Marty’s dad just had a pacemaker implanted in his chest to control his irregular heartbeat.  Marty argues that his dad’s circulatory system used to be a natural system, but it is now a human-made system because it is controlled by the pacemaker.  Do you agree or disagree with this statement?  Explain your reasoning.

  5. Do you think a natural or human-made system is more reliable?  Give three examples to explain your reasoning.

Answer Key/Rubric

  1. Acceptable responses may include, but are not limited to:
  • Water cycle
  • Carbon cycle
  • Nitrogen cycle
  • Star cycle
  • Rock cycle
  • Body systems (reproductive, digestive, circulatory, etc.)
  • Lifecycles (butterfly, frog, human, flowering plant, etc.)
  1. Acceptable responses may include, but are not limited to:
  • Railways
  • Bus schedules
  • Electrical systems
  • Metric system
  • Binary system
  1.  Acceptable responses may include, but are not limited to:
  • Stellar nebula
  • Main sequence (can remain in this stage for billions of years – produce energy through the fusion of hydrogen into helium)
  • Red giant (helium fuses into carbon)
  • Planetary nebula
  • White dwarf (can remain hot for billions of years)
  1. Acceptable responses may include, but are not limited to:
  • The circulatory system is a natural system.
  • The heart is the pump of the circulatory system.
  • A pacemaker is a human-made device that helps to regulate the heartbeat.
  • If a pacemaker is implanted, you have introduced a human-made component into the circulatory system.
  • The pump of the circulatory system is now human-made.  The pattern of the circulatory system will continue by force of the human-made component.
  • The majority of the pattern of the circulatory system is natural.
  1. Acceptable responses may include, but are not limited to:
  • Natural systems repeat patterns automatically.
  • Natural systems can adapt to fix their problems.  This usually does not create a large disruption.
  • Human-made systems may be interrupted.
  • Sometimes solutions to interruptions are complex.  Therefore, pattern may halt for a period of time.
