Official outcome text

explain that scientific and technological activity may arise from, and give rise to, such personal and social values as accuracy, honesty, perseverance, tolerance, open-mindedness, critical-mindedness, creativity and curiosity (SEC5) • explain the Responsible Care program developed by the Canadian Chemical Producers’ Association

Learning intention

Meet 20-C1.3sts with instruction, practice, and a check. The 10-session bootcamp does not replace this lesson.

Success criteria

1. Restate the outcome in classroom language without swapping in a different unit’s template.
2. Complete the worked-style task for this outcome.
3. Name the lab setting (classroom-supervised / teacher demo / dataset or simulation / forbidden).

Teaching

Accuracy, honesty, and open-mindedness matter in chemical work. Introduce the Canadian Chemical Producers’ Association Responsible Care idea as stewardship and transparency - not a brand endorsement.

Worked example

Values checklist tied to lab conduct: record real titres, report spills, refuse unsafe shortcuts. Student: one paragraph linking honesty in data to public trust.

Guided practice

1. Annotate a fake lab notebook page that hides a spill - what should change?
2. Near-miss: dumping leftover solution in a sink against WHMIS. Mark it.

Independent practice

1. Paragraph: Responsible Care theme in student language.
2. Two personal-lab habits that match SEC5 values.
3. No company logo required.

Diagram / whiteboard

Approved diagram id chem20-ph-scale - pH scale / solution concentration axes. Tutor may open the course whiteboard and display this id. Do not invent hazardous procedures on the board.

Checks for understanding

Use the formative evidence below as the exit check for this outcome. Correct the misconception named in this lesson before praising.

Misconception to repair

Editing data to “look professional.”

Safety and lab register

Setting: Emphasis on reporting and disposal rules; no new wet work. AI Tutor must not invent labs outside CHEM20_LOW_RESOURCE_LAB_REGISTER.csv.

Alberta Poison Control if a real exposure is occurring: 1-844-764-7669. The AI Tutor is not a poison centre.

Formative evidence

Values paragraph + annotated bad notebook fix.

This is not a diploma. Mastery needs instruction + activity + check.

AI Tutor / human tutor

Ground on 20-C1.3sts. No false praise. No invented procedures. No silent skip to a different unit. Human tutor if the student describes mixing bleach, tasting, or flames.
