1-Metal Properties + Biomimicry (PBa)

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
