Lesson Topic: Quality control (QC) checks to be used on a made product. (Quality control checks are made to a finished product to see if it meets the quality standards set.)
Learning Objective/s:
  • Describe the purpose and importance of QC checks for finished products.
  • Identify and differentiate the main types of QC checks (dimensional, visual, functional, material, safety, documentation).
  • Apply a systematic QC process to evaluate a product and record results using a checklist.
  • Analyse QC data to suggest improvements and corrective actions.
Materials Needed:
  • Projector or interactive whiteboard
  • Printed QC checklist templates (e.g., wooden chair example)
  • Sample product or prototype for inspection
  • Calipers, micrometer, protractor, ruler
  • Surface roughness gauge or profilometer (or images)
  • Safety testing equipment (insulation tester, load cell)
  • Worksheets for students to record findings
 Introduction:
Begin with a short video showing a product failing a QC test, prompting discussion about why quality control matters. Recall previous lessons on design specifications and measurement tools. Explain that today’s success criteria are to correctly select appropriate QC checks, conduct a mock inspection, and complete a QC checklist.
Lesson Structure:
  1. Do‑now (5'): Students list three reasons QC is essential; teacher reviews responses.
  2. Mini‑lecture (10'): Overview of QC types and stages using slides and a flowchart diagram.
  3. Demonstration (15'): Teacher conducts visual and dimensional inspection on a sample chair, showing equipment and recording on a checklist.
  4. Group activity (20'): Pairs perform a full QC inspection on a provided product, using calipers, protractor, and safety test kit; fill out their checklist.
  5. Data analysis (10'): Groups compare results, identify non‑conformances, and suggest corrective actions.
  6. Plenary (5'): Whole‑class recap of key steps; exit ticket where each student notes one QC method they found most useful.
Conclusion:
Recap the sequential QC process from preparation to final acceptance and emphasise the role of accurate recording for traceability. Students complete an exit ticket stating one improvement they would make to the checklist. For homework, each student drafts a QC checklist for a product of their choice to bring to the next lesson.
