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 a gene mutation.
  1. How is a gene mutation similar to an adaptation?  How is it different?

  2. Summarize how a gene mutation occurs.
  1. While learning about gene mutations in science class, Jamal came to the conclusion that they are more harmful than helpful.  Do you agree with him?  Use facts to justify your reasoning.

Answer Key/Rubric

  1. A gene mutation is any change in DNA.

  2. Acceptable responses may include, but are not limited to:

    • An adaptation helps a plant or animal survive in its environment.
    • Gene mutations may or may not help a plant or animal adapt to its environment.
    • The mutation may increase the probability of survival.
    • A gene mutation could harm the organism.
    • A gene mutation happens in one organism.
    • A gene mutation may not be passed down to future generations.

  3. Acceptable responses may include, but are not limited to:

    • A mutation is an error that occurs while copying DNA.
    • DNA is composed of nucleotide bases.  These bases form specific bonds.
    • The DNA might pair incompatible bases within the chain.
    • The DNA might delete a base.
    • The DNA might add an extra base.
    • DNA can also be damaged by environmental factors such as UV radiation, x-rays, or toxins.
  1. Acceptable responses may include, but are not limited to:

    • The mutation may not have an effect on the organism.
    • If a mutation occurs in a noncoding region of DNA, then it will mostly likely have no effect on the organism.
    • The mutation may have a minor effect.  Minor effects include hair color, skin color, height, etc.
    • The mutation may cause a genetic disorder.
    • The mutation may cause a genetic disease.
