CareerStart lessons: Grade eight

These lessons will help students understand how classroom lessons about technology, water quality and the hydrosphere, cell theory and plant respiration, microbiology, remote sensing, biological and geological evolution, and chemical processes are applicable to future careers.

The lessons address the following questions:

  • Lesson 1: Which career paths involve the study of science?
  • Lesson 2: How is technology defined?
  • Lesson 3: How can water quality be improved by the actions of various professionals and by the personal choices of community members?
  • Lesson 4: Why do plants need sunlight to carry on cell respiration and photosynthesis?
  • Lesson 5: What are the physical and functional characteristics of bacteria?
  • Lesson 6: How can satellite images be used to monitor the earth from space?
  • Lesson 7: How does geological change influence biological evolution?
  • Lesson 8: How do the properties of materials determine their uses?
  • Lesson 9: What effect does salt have on the freezing point of water?
  • Lesson 10: How can knowing the physical properties of a substance help to identify it?
