    • Copy other groups names onto your own table
    • Notes on atoms vs ions using diagrams and electron shell configurations
    • Notes on creating ionic compounds
    • Use whiteboards in table groups to make compounds as a quiz/speed game
  4. Ionic Compounds
    • Finish quiz/speed game
    • Ionic compounds Quizlet
    • Writing formulae worksheet #1

  14. Gas Tests
    • Instruct students to make notes in their books as they go through each whakamātau
    • Notes should include success criteria and a diagram for how to set up the whakamātau
    • Gas tests whakamātaus
    • Fill in notes on gas tests in the research document if time.
  15. Practice Test
    • Issue booklet for practice assessment
    • https://pūtaiao.lesueur.nz/11sci/as90947/slides/assessment-tips.html
    • Go through how the assessment will work
    • Make predictions & complete word/symbol equations before starting whakamātau work
    • https://www.riskassess.co.nz/risk_assessment/8368055
  16. Continue Practice Test
  17. Feedback/Compare & Contrast
    • Give class-wide feedback on how to improve (assessment tips in ngā kirita)
    • Split the class into two:
      • One part learns how to do the excellence compare and contrast
      • Other part continues work on their research documents & revises for the actual test
