• Course: CHEMISTRY20 (SCN2796)
• Lesson ID: CHEMISTRY20-U3-L37

• Object type: canonical lesson (not a bootcamp session)
• Source: Alberta Chemistry 20 Program of Studies (2007, updated 2014)

Official outcome text

work collaboratively in addressing problems and apply the skills and conventions of science in communicating information and ideas and in assessing results • research, collectively, the relationship between sulfuric acid and industrialization (CT-SEC1) [ICT C1-4.1, C2-4.1] • evaluate technologies used to reduce emissions that lead to acid deposition (CT-SEC1) [ICT C6-4.5]

Learning intention

Meet 20-C2.4s 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

Team research: sulfuric acid and industrialization (historical); evaluate emission-reduction technologies for acid deposition using pack sources.

Worked example

Two-slide outline: (1) historical sulfuric acid use, (2) scrubbers/catalytic ideas as emission control - cite pack links. Peer critique for overclaiming.

Guided practice

1. Draft the two slides with citations.
2. Near-miss: invented FNMI industrial story. Hold review.

Independent practice

1. Peer critique checklist applied.
2. One limitation sentence.
3. No plant tour 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

Claiming a student scrubber design is field-ready.

Safety and lab register

Setting: Research only. 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

Two-slide outline + peer critique.

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

AI Tutor / human tutor

Ground on 20-C2.4s. No false praise. No invented procedures. No silent skip to a different unit. Human tutor if the student describes mixing bleach, tasting, or flames.
