Safer Designs That Help

Overview

Today students view a short, teacher-made video presentation about designs that enhance people’s lives while considering safety. They then use a simple checklist to explain which competing factors were considered, including sustainability.

Learning intentions

Students will:

• explain how designs can enhance people’s lives
• identify safety features in everyday products, services, or environments
• explain competing factors designers must balance, including sustainability
• practise using design language to give a clear, justified explanation

Success criteria

• I can name one way a design improves someone’s life.
• I can describe at least one safety consideration in the design.
• I can explain one competing factor (for example safety vs cost, or safety vs sustainability).
• I can give a clear reason for why that choice matters.

Curriculum links

• AC9TDE6K01: explain how people in design and technologies occupations consider competing factors including sustainability in the design of products, services and environments
• AC9TDE6P03 (supporting link): select and use suitable materials, components, tools, equipment and techniques to safely make designed solutions (used today through safety-focused thinking, not construction)

Lesson structure (20 minutes)

1. 0–3 min · Video preview and hook. Teacher briefly introduces the idea of “better for people” and “safer for people,” then plays the video title card and one opening question. Student states one product/service they use and guesses what makes it safer.

2. 3–10 min · Watch video: designs and safety. Teacher plays the video presentation in segments (stop once for prediction). Student listens for examples of safety features and competing factors, recording 2 notes on a teacher-provided response sheet.

3. 10–14 min · Guided check: competing factors. Teacher pauses the video and models how to turn notes into an explanation using sentence starters. Student answers: “The design helps by… The safety feature is… One competing factor is… Designers balance this because…”

4. 14–18 min · Mini case study (one example). Teacher selects one video example (for example, a bicycle helmet design, a child-safe medication dispenser, or a safer public walkway with low-impact access) and displays a simple checklist. Student completes the checklist: benefit, safety, and sustainability (or another competing factor if sustainability isn’t obvious in the example).

5. 18–20 min · Exit ticket. Teacher gives one final prompt and collects responses. Student writes one paragraph: “Designers consider competing factors… including sustainability… because…”

Resources

• Printed or single-page response sheet with sentence starters and a checklist
• Teacher-made short video presentation (4–6 minutes total) with 2 built-in pause questions
• Timer for lesson steps
• Visuals in the video (images or short clips of products/services/environments with safety features)
• Writing materials (pencil, lined paper) or an accessible digital note form

Assessment

• Formative observation during video: student can correctly identify at least one safety feature
• Checklist review: student includes benefit and a reasoned competing factor (including sustainability when possible)
• Exit ticket paragraph: clarity, specific details, and correct use of design language (benefit, safety, competing factors)

Differentiation

• Support: provide sentence starters and a word bank (safety, feature, helps, protects, reduces risk, sustainability, materials, environment, trade-off).
• Support: allow the student to choose from 2–3 video examples and complete the checklist for only one.
• Challenge/extension within the lesson: if the student finishes early, ask them to add a second competing factor (for example safety vs comfort; sustainability vs cost) and explain how the designer balanced it.
• SEN/EAL considerations: accept oral responses first, then record key phrases; use shorter sentences and allow diagram/labeling on the checklist.

Video presentation guidance (for the teacher to use)

• Slide/segment 1 (0:00–1:30): “Designs that help people” with one everyday example (e.g., child-resistant packaging or a smoke alarm). Pause question: “What problem is this design solving for people?”
• Slide/segment 2 (1:30–3:00): “Safety features” (prevention, protection, clear instructions). Pause question: “What safety feature do you notice, and who benefits?”
• Slide/segment 3 (3:00–5:00): “Competing factors and sustainability” (example: using safer materials but also considering waste, recyclability, or energy use). Teacher models an explanation: “Designers balance safety with sustainability by…”
• Slide/segment 4 (5:00–6:00): Wrap-up: students see a simple checklist for explaining benefit + safety + competing factors. Prompt for student: “Turn your notes into one explanation.”

If you tell me which specific video example you want to use (helmet, medication dispenser, walkway/boardwalk, battery-powered toy, recycling service, etc.), I can tailor the checklist prompts and sentence starters exactly to that case.
