Grade: Date: 25/02/2026
Subject: Design and Technology
Lesson Topic: Product testing methods that can be used before or during the manufacturing of products, such as: material testing, dimensional checks, joining/assembly checks, visual checks.
Learning Objective/s:
  • Describe the purpose of material, dimensional, joining/assembly and visual testing in product development.
  • Explain how each testing method is applied at specific stages of manufacturing.
  • Evaluate test results to determine compliance with specifications and decide on product release.
  • Apply basic documentation procedures for recording test data in a quality management system.
Materials Needed:
  • Projector and screen
  • PowerPoint presentation on testing methods
  • Sample product components (metal rod, plastic part)
  • Calipers, micrometer, and torque wrench
  • Handouts with test method tables
  • Worksheets for case‑study analysis
 Introduction:
Begin with a short video showing a product failure caused by inadequate testing, prompting students to consider why testing matters. Recall prior knowledge of quality systems and the role of specifications. Explain that today they will explore four key testing methods and will be able to select appropriate tests for a given manufacturing stage. Success criteria: students can describe each method, explain when it is used, and record test results correctly.
Lesson Structure:
  1. Do‑now (5'): Students answer a quick question on a product failure they have seen. (Check understanding)
  2. Mini‑lecture (10'): Overview of why testing is essential and the QMS flow. (Presentation)
  3. Interactive demonstration (15'): Show material testing equipment (UTM) and dimensional tools; discuss purpose.
  4. Group activity (20'): Given a case study, groups decide which tests to apply at each stage and fill a test‑plan worksheet. (Teacher circulates)
  5. Whole‑class debrief (10'): Groups share decisions; teacher clarifies misconceptions.
  6. Quick quiz (5'): Exit ticket – match test method to manufacturing stage.
Conclusion:
Summarise how the four testing methods ensure product quality and fit within a QMS. Students complete an exit ticket matching tests to stages, reinforcing recall. Assign homework to research a real‑world example of a testing failure and propose improvements.
