Instructional Ideas

  • Pre-teach parts per notation before working through the rest of the lesson
Classroom Considerations

  • Relies on prior knowledge of algebra, solving for volume and surface area of spheres, scientific notation, metric units, and density
  • Lesson works as an extension to the short film The Day the Mesozoic Died, but stands alone if needed

  • Provides two versions, one with guided calculations and the other without
  • Designed to connect math and science concepts

  • None
