Description
This lesson guide integrates a series of activities designed to look at stellar evolution and composition.

Objectives
Students will:
• Discuss the basic steps of stellar evolution and contrast them with Navajo creation stories.
• Discriminate between samples representing elemental abundances in the solar system.
• Discuss the fusion process in a star.

Lesson Activities and Sequence
The suggested sequence introduces students to stellar evolution then progresses to stellar and universe composition.
  1. Cycles in the Cards
    Students explore stellar evolution and draw parallels to Navajo creation stories.
    Keywords: Native Americans, star cycles

  2. Elements and You
    Students investigate elemental abundances in the universe using random sampling.
    Keywords: chemistry, elements, fusion, star cycles, stellar evolution

  3. What's Out There
    Students look at dry food mixtures in sealed bottles to compare elemental abundances in stars and other celestial bodies.
    Keywords: chemistry, elements, fusion, star cycles, stellar evolution
