Chemistry 20 - Materials research and technology (STS)
LESSON = canonical instructional unit covering official Chemistry 20 outcomes. SESSION = bootcamp delivery event. A bootcamp session may overlay several Unit A lessons.

Unit A: Diversity of Matter and Chemical Bonding - outcome 20-A1.3sts
- Course: CHEMISTRY20 (SCN2796)
- Lesson ID:
CHEMISTRY20-U1-L09 - Official outcome:
20-A1.3sts(STS) - Object type: canonical lesson (not a bootcamp session)
- Source: Alberta Chemistry 20 Program of Studies (2007, updated 2014)
Official outcome text
explain that scientific knowledge may lead to the development of new technologies, and new technologies may lead to or facilitate scientific discovery (ST4) [ICT F2-4.4, F2-4.8] • explain how scientific research and technology interact in the production and distribution of beneficial materials, such as semiconductors, ceramics and composite materials
Learning intention
Meet 20-A1.3sts with instruction, practice, and a check. The 10-session bootcamp does not replace this lesson.
Success criteria
- Restate the outcome in classroom language without swapping in a different unit’s template.
- Complete the worked-style task for this outcome.
- Name the lab setting (classroom-supervised / teacher demo / dataset or simulation / forbidden).
Teaching
Science and technology push each other: research on bonding and lattices informs ceramics, semiconductors, and composites; new tools then enable more precise measurements. Stay with POS examples; do not invent FNMI stories (FNMI_LOCAL_REVIEW if a vetted source is later approved).
Worked example
Example chain: understanding ionic/covalent bonding → engineered ceramics / semiconductor doping language in a textbook figure → better conductivity or hardness measurements → revised models. Student product: one-page brief naming one material class (ceramic, semiconductor, or composite) and one property tied to bonding - no lab fabrication.
Guided practice
- Outline the brief: material class, one bonding idea, one property, one measurement tool (named, not built).
- Near-miss: “grow crystals with drain cleaner.” Forbidden.
Independent practice
- Finish the one-page brief with classroom-safe sources only.
- Two sentences: ST4 - science ↔ technology interaction.
- No FNMI invention checkbox signed.
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
Writing a maker-project that requires kiln firing or etching acids at home.
Safety and lab register
Setting: Paper research only. No etching, no kiln, no concentrated acids. 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
One-page materials brief skeleton completed.
This is not a diploma. Mastery needs instruction + activity + check.
AI Tutor / human tutor
Ground on 20-A1.3sts. No false praise. No invented procedures. No silent skip to a different unit. Human tutor if the student describes mixing bleach, tasting, or flames.
