Lesson Plan

Name Description
How to Make a Monkey Glow in the Dark

This lesson focuses on mutations and genetic recombination and how they increases the diversity of a population. The concept is presented as a PowerPoint, computer activity, and literacy article. Glow in the dark monkeys, spider goats, and modern biotechnology are used as attention grabbers.

Text Resources

Name Description
Genetic Solution to Cancer, Diabetes?

This informational text resource is intended to support reading in the content area. The text describes a rare form of dwarfism called Laron's Syndrome, which is associated with an unusually low incidence of cancer and diabetes. This combination of characteristics allows scientists to speculate on the relationship between all three conditions. It appears that a mutation that causes dwarfism protects against the common diseases of cancer and diabetes.

Bacteria Learn New Trick

This informational text resource is intended to support reading in the content area. This article shows how, through experimentation, bacteria evolve over a short period of time. The E.coli bacteria show the ability to eat a new food, citrate, after 13,000 generations of gene mutation.

Tutorial

Name Description
Variation in a Species

This Khan Academy video explains how variation can be introduced into a species and the importance of sexual reproduction in this process.

Video/Audio/Animation

Name Description
Variation Is Essential: How Does Variation Within a Population Affect the Survival of a Species?

This is a lesson about phenotypical variation within populations and how these differences are essential for biological evolution. Students will use a model organism (in this case, kidney beans) to explore variation patterns and subsequently connect these differences to artificial & natural selection. The NGSS’ CrossCutting Concepts and Science & Engineering Practices are embedded throughout the lesson.

The main learning objectives are:

  • Using a model (kidney beans) to explore the natural variations within a population.
  • Measuring differences between individuals in a population (population of beans).
  • Describing how genetic/phenotypic variation is a key part of biological evolution because it is a prerequisite for natural selection.
  • Demonstrating in which ways genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

The NGSS Performance Expectations covered are HS-LS4-2. & HS-LS4-4.
