Molarity Jeopardy

Other Chemistry lessons: Add 'Em Atom and Electron Configuration

  • Subject Area: Chemistry
  • Age or Grade: Juniors/Seniors
  • Estimated Length: 80 minutes
  • Prerequisite knowledge/skills: Students have completed the unit on molarity.
  • Description of New Content: This is a review game of molarity.
  • Goals: Students will be able to answer questions about moles, molecules, grams, molarity, and toxicity to prepare for their exam.
  • Materials Needed:
  • Procedure:
    • Opener:
      1. Review with students the formulas for molar mass (atomic mass = 1 mole), molecules (6.02 x 10^23 molecules = 1 mole), molarity (mole/liter), and toxicity (weight in kg * LD50).
    • Development:
      1. Divide class into 2 teams.
      2. Show the 5 categories. Explain that higher point questions are harder.
      3. Explain that each team must elect a captain, who will be the person to give the final answer.
      4. Explain that team 1 will choose a question to answer. Team 2 must also prepare to answer the question in case team 1 gives an incorrect answer. The team with the most points wins!
    • Closure:
      1. Suggestion: offer extra credit or free homework grade to the winners (although no incentive was necessary for a heated competition!).
  • Evaluation: Students had the citywide final exam.
  • Extensions: Students could make their own jeopardy questions (and provide the answers) to give to the other team.
