Units / Unit A / Acids, Bases, Properties, and WHMIS
Acids, Bases, Properties, and WHMIS
Classify compounds by properties; WHMIS-aware safe practices (A-GO2-SO1, SO5, SO8).
Lesson plan — step by step
- 1
Prepare
Demo: conductivity tester, pH strips, WHMIS pictograms.
- 2
Set purpose
Display learning-intent slide; clarify success criteria and POS tags.
- 3
Teach
Walk through 8 slides in order—use talk tracks and questions in presenter notes.
- 4
Formative check
Safety scenario: Given spill scenario, identify WHMIS steps.
- 5
Close
Exit slide; assign optional review of student notes online.
Materials
- Demo: conductivity tester, pH strips, WHMIS pictograms.
