Every designed solution is built from materials (like wood, metal, plastic or fabric) and often systems — components working together, like gears, circuits or mechanisms, that use force, motion and energy to function. Choosing the right materials, tools and components depends on the properties needed for the job — strength, flexibility, cost or appearance. Once a design is finalised, making it safely means selecting and correctly using suitable tools, equipment and processes, following safety procedures to protect yourself and others throughout production.
Example
A simple wind-up toy car uses a spring (storing energy), gears (transferring motion), and a plastic body (lightweight and cheap to produce) — each material and component chosen for a specific reason related to how the system needs to function.
Key terms
System:
A set of components working together to perform a function, like a mechanism or circuit.
Properties (of materials):
Characteristics like strength, flexibility or durability that affect what a material is suited for.
Safety procedure:
A set of steps followed to reduce risk when using tools or equipment.
Questions
1. A material used in design might be:
Only imaginary
Wood, metal, plastic or fabric
Nothing physical
Irrelevant to design
2. A system is:
A single isolated part
A set of components working together to perform a function
Unrelated to design
Always electronic
3. Properties of materials include:
Only colour
Strength, flexibility and durability
Nothing measurable
Random guesses
4. Force, motion and energy are used in:
Nothing related to design
Engineered systems
Only imaginary machines
Unrelated fields
5. Making a design safely involves:
Ignoring safety entirely
Following safety procedures with tools and equipment
Random unsafe practices
Skipping safety training
6. Choosing the right material depends on:
Nothing important
The properties needed for the job
Random selection only
Ignoring the design's requirements
7. A safety procedure is:
Optional and unimportant
A set of steps to reduce risk
Irrelevant to making things
Only for professionals
8. A wind-up toy car uses a spring mainly to:
Add colour
Store and release energy
Make noise
Add weight only
9. Gears in a mechanical system are used to:
Store energy only
Transfer motion between parts
Add decoration
Absorb sound
10. Choosing plastic for a lightweight, cheap product reflects:
Random selection
Matching material properties to the design's needs
Ignoring cost entirely
No real reasoning
11. Why must tools and equipment be selected and used correctly?
Safety and quality have no connection to tool use
To safely and effectively produce the intended design
Tool choice never matters
Any tool works for any task
12. Analysing needs and selecting suitable materials, tools and processes together is part of:
Ignoring the design process
Planning how to create a designed solution
A random, unplanned activity
Only the final testing stage
13. Force, motion and energy in an engineered system might include:
Only imaginary concepts
A spring storing energy and a gear transferring motion
Nothing related to real mechanisms
Unrelated to engineering
14. Why might a designer test a material's strength before using it in a product?
Testing has no value
To ensure the material can handle the demands of its intended use
Strength is irrelevant to design
Materials never need testing
15. A product requires flexibility but a designer chooses a rigid material. What is the likely consequence?
No consequence at all
The product may not perform as intended or could fail under use
Flexibility is never actually needed
The product will automatically work perfectly
16. Why might understanding both materials AND systems be necessary for many real design solutions?
Materials and systems are unrelated to each other
Effective solutions often need suitable materials working together within a functioning system
Only materials ever matter in design
Systems have no connection to physical materials
17. A student skips following safety procedures while using workshop tools to save time. What risk does this create?
No risk, since safety procedures are optional
Increased risk of injury or damage, since procedures exist to manage real hazards
Time savings always outweigh safety
Safety procedures have no real purpose
18. Why might combining several different materials (like metal, plastic and fabric) in one product make sense?
Products should only ever use one material
Different materials can be chosen for the specific properties each part of the product needs
Combining materials always fails
Material combinations have no real benefit
19. A gear system fails to transfer motion effectively in a prototype. What should a designer do?
Ignore the failure and finalise the design anyway
Investigate the issue and iterate on the system's design
Abandon systems and mechanisms entirely
Assume it will fix itself
20. Understanding materials, systems and safe production mainly helps students:
Avoid ever making physical solutions
Design and safely produce solutions that function as intended
Ignore how things are actually built
Skip understanding how components work together
