Unit A: Diversity of Matter and Chemical Bonding - outcome 20-A1.3s

• Course: CHEMISTRY20 (SCN2796)
• Lesson ID: CHEMISTRY20-U1-L12
• Official outcome: 20-A1.3s (SKILL)
• Object type: canonical lesson (not a bootcamp session)
• Source: Alberta Chemistry 20 Program of Studies (2007, updated 2014)

Official outcome text

analyze data and apply mathematical and conceptual models to develop and assess possible solutions • analyze experimental data to determine the properties of ionic compounds (AI-NS6) [ICT C7-4.2] • use data from various sources to predict the strength of bonds between ions (PR-NS1, AI-NS2) [ICT C6-4.1]

Learning intention

Meet 20-A1.3s 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

Analyze: use experimental or table data to decide which solids behave as ionic (high MP card, aqueous conductivity) vs molecular. Bond-strength talk stays qualitative unless numbers are given.

Worked example

Given Table S04: NaCl(aq) conducts, sucrose does not; NaCl MP card high, sucrose lower. Conclusion: aqueous ion mobility explains conductivity; lattice strength explains MP - not “electrons in crystals.”

Guided practice

1. Write a CER using only Table S04 + MP cards.
2. Near-miss: a KMT essay dropped into this analysis. Mark wrong-unit.

Independent practice

1. Predict conductivity of dry NaCl vs NaCl(aq) and check against the model.
2. Two sentences: limitation - one trial, one probe.
3. SI units for any numerical conductivity if the probe reports them.

Diagram / whiteboard

Approved diagram id chem20-ionic-lattice - Ionic lattice / bonding sketch. 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

Averaging unrelated units (mixing gas-law pressures into bonding conclusions).

Safety and lab register

Setting: Analysis is paper. No new wet work beyond approved sources. 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

CER paragraph + limitation sentence.

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

AI Tutor / human tutor

Ground on 20-A1.3s. No false praise. No invented procedures. No silent skip to a different unit. Human tutor if the student describes mixing bleach, tasting, or flames.
