Unit D: Quantitative Relationships in Chemical Changes - outcome 20-D1.4s

• Course: CHEMISTRY20 (SCN2796)
• Lesson ID: CHEMISTRY20-U4-L10
• Official outcome: 20-D1.4s (SKILL)
• 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 • use integrated software effectively and efficiently to incorporate data and text (AI-NS3, CT-ST2) [ICT P4-4.3]

Learning intention

Meet 20-D1.4s 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

Teamwork: share calculation sheets with data and text; check peers’ unit cancellation.

Worked example

Peer checklist: formulas, balance, mole ratio, units, sig figs. Sample error: forgetting 2:1 ratio.

Guided practice

1. Mark a provided wrong solution at the first error line.
2. Near-miss: editing peer numbers to match. Integrity fail.

Independent practice

1. Peer-check two calculations.
2. Two sentences: how to give corrective feedback.
3. Software optional.

Diagram / whiteboard

Approved diagram id chem20-stoich-mole-map - Mole map stoichiometry flow. 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

False praise of a wrong ratio.

Safety and lab register

Setting: Paper peer review. 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

Annotated wrong solution + two peer checks.

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

AI Tutor / human tutor

Ground on 20-D1.4s. No false praise. No invented procedures. No silent skip to a different unit. Human tutor if the student describes mixing bleach, tasting, or flames.
