Unit A: Diversity of Matter and Chemical Bonding - outcome 20-A1.2s

• Course: CHEMISTRY20 (SCN2796)
• Lesson ID: CHEMISTRY20-U1-L11
• Official outcome: 20-A1.2s (SKILL)
• Object type: canonical lesson (not a bootcamp session)
• Source: Alberta Chemistry 20 Program of Studies (2007, updated 2014)

Official outcome text

conduct investigations into relationships among observable variables and use a broad range of tools and techniques to gather and record data and information • draw electron dot diagrams (CT-NS2) • build models of ionic solids (CT-NS2) • perform an investigation to illustrate properties of ionic compounds (PR-NS3, PR-NS5) • use the periodic table to make predictions about bonding and nomenclature (PR-NS1, AI-NS1) • use model-building software to collect and integrate information on the structure of ionic crystals (PR-NS4) [ICT C6-4.4]

Learning intention

Meet 20-A1.2s 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

Perform and record: electron-dot diagrams, paper or kit ionic lattice models, and conductivity/solubility results from Session 04 or the provided table. Periodic table predictions before naming.

Worked example

Record sheet: (1) Lewis transfer Na + Cl. (2) Paper lattice sketch Na+/Cl−. (3) Conductivity: NaCl(aq) vs sucrose(aq) from class or Table S04. (4) Prediction: K and Br form KBr ionic - confirm with naming rules.

Guided practice

1. Complete the record sheet with actual class or table numbers - no blanks filled by guess.
2. Near-miss: tasting solids to “identify.” Forbidden.

Independent practice

1. Dot diagram for MgO transfer.
2. One lattice model photo/drawing with labels.
3. One conductivity row from the register source you used.

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

Skipping the data table and inventing LED results.

Safety and lab register

Setting: Models paper/kit. Wet work only under CHEM20-LR-04 classroom rules. 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

Filled record sheet with source named (Session 04 or dataset).

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

AI Tutor / human tutor

Ground on 20-A1.2s. No false praise. No invented procedures. No silent skip to a different unit. Human tutor if the student describes mixing bleach, tasting, or flames.
