Question 1

What is the difference between hardwood and softwood?

Accepted Answer

Hardwood comes from deciduous (broad-leaved) trees; softwood comes from coniferous (needle-leaved) trees — though not always harder in texture

Answer

Hardwood (oak, teak, mahogany) comes from deciduous trees with broad leaves. Softwood (pine, cedar, spruce) comes from coniferous trees. The terms refer to tree type, not necessarily hardness.

Question 2

In food technology, what does 'food hygiene' include?

Accepted Answer

Maintaining cleanliness of hands, tools, surfaces, and food itself to prevent contamination and foodborne illness

Answer

Food hygiene involves: washing hands, sanitising surfaces and utensils, proper food storage (correct temperatures), avoiding cross-contamination, and maintaining personal hygiene when handling food.

Question 3

What is the purpose of a 'design brief' in design and technology?

Accepted Answer

A document that outlines the design problem, requirements, constraints, and context that the designer must address

Answer

A design brief sets out what needs to be designed, for whom, why, and any constraints (budget, materials, size). It guides the entire design process from start to finish.

Question 4

What does 'ergonomics' mean in product design?

Accepted Answer

Designing products and environments to fit the user's physical and cognitive needs for comfort, efficiency, and safety

Answer

Ergonomics is the science of designing products, systems, and environments to fit users' physical and mental characteristics, reducing discomfort, injury, and inefficiency — e.g., an ergonomic chair supports posture.

Question 5

What safety precaution should you take when soldering in electronics?

Accepted Answer

Work in a well-ventilated area, wear safety glasses, use a soldering stand, and wash hands after — solder fumes and lead are hazardous

Answer

Soldering produces hazardous fumes from flux — ventilation is essential. Safety glasses protect from splashes. A soldering iron stand prevents burns. Lead in solder is toxic — wash hands thoroughly after work.
