Why is aluminium suitable for making a lamp?
It is ferrous and rusts easily
It is heavy and hard to bend
It is malleable and does not rust
It is magnetic and brittle
What happens when aluminium is exposed to air?
It corrodes quickly
It forms a protective oxide layer
It becomes magnetic
It melts
Which property of aluminium makes it suitable for bike frames?
High electrical conductivity
High strength-to-weight ratio
High hardness
Low recyclability
Why is aluminium used for drinks cans?
It is very hard and brittle
It is magnetic
It is malleable and easy to shape
It is expensive and rare
What does “non-ferrous” mean?
Contains iron and rusts
Does not contain iron and does not rust
Is magnetic
Is very heavy
What is biomimicry?
A method of recycling metals
A way to make metals stronger
Innovation inspired by nature
A type of metal coating
Which of the following is a benefit of aluminium recycling?
It takes years to recycle
It uses more energy than making new aluminium
It saves 95% of energy compared to producing new aluminium
It cannot be recycled
What is the main goal of biomimicry in design?
To copy nature for decoration
To solve design problems sustainably by learning from nature
To make products look like animals
To reduce the cost of manufacturing
Which of the following is an example of biomimicry?
A plastic bottle shaped like a tree
A fan designed to look like a flower
A train nose cone inspired by a kingfisher’s beak
A lamp painted with animal patterns
Why is the kingfisher bird often used as inspiration in biomimicry?
It is colourful and attractive
It moves silently and efficiently through water and air
It is endangered and needs protection
It builds nests in trees
What aspect of shark skin has inspired modern design?
Its colour-changing ability
Its ability to repel water and reduce drag
Its flexibility
Its ability to glow in the dark
How does biomimicry help the environment?
It uses more plastic
It encourages copying animal behaviour
It promotes sustainable and energy-efficient solutions
It increases the use of fossil fuels
Which of these is a benefit of using biomimicry in product design?
Products are more expensive
Designs are less efficient
Nature-inspired solutions often reduce waste and energy use
Products are harder to manufacture
Why might designers look to nature for inspiration when creating new products? (DoK Level 2)
Nature provides examples of efficient and sustainable solutions
Nature is always easy to copy
Nature-inspired designs are always cheaper
Nature discourages innovation
Imagine a company wants to reduce the energy use of its products. Based on the principles of biomimicry, what should the company do? (DoK Level 3)
Ignore natural processes and focus on traditional methods
Study how organisms in nature solve similar problems efficiently
Increase the use of fossil fuels
Make products more complex without considering nature

Because it is strong and resistant to corrosion
Because it is a good conductor of electricity
Because it is soft and easy to bend
Because it is transparent
Imagine you are designing a new screwdriver. Which material would you choose for the driver tip and why?
Hardened steel, because it is durable and can withstand wear
Copper, because it is a good conductor
Gold, because it is valuable
Aluminum, because it is lightweight
If you were to design a modern bicycle frame, which metal would you select and what property makes it suitable?
Aluminum, because it is lightweight and strong
Lead, because it is dense
Copper, because it is a good conductor
Gold, because it is shiny
Why is high-speed steel used for making drill bits?
Because it can withstand high temperatures and is very hard
Because it is lightweight and flexible
Because it is a good conductor of electricity
Because it is easy to melt
