Science of Materials - Seeking microfibres

An assessment quiz to accompany our KS2 lesson plan about textiles, where students find out about microfibres and learn how to extract them from a fleece.
START
What are textiles?
Textiles is the name given to cloth fabric woven from yarn. We use them to make clothes, bedding and towels.
Next
What properties do textiles have?
Textiles are amazing! They keep us warm or cool. Can be dry or wet. Can be washed - or don't like being washed at all!

Different fabrics show different properties, depending what they're made from or how they have been treated. This is why we use them for different things.
Next
What is polyester fleece made from?
Plastic is made from oil. This is a non-renewable resource, dig up from underground or under the sea. We have a limited amount of it and cannot produce any more once we have used it up.
Next
What are microplastics?
Microplastics are tiny pieces of plastic. They end up all over the place as they are so small and easily washed into rivers and into the sea.
Next
Where do microplastics and microfibres come from?
All plastic objects break into smaller and smaller pieces over time. They never disappear. They remain in the environment and can affect wildlife and our natural world.
Next
How many microfibres does a polyester fleece produce?
As you could find out in the experiment fleeces produce many, many small plastic particles called microfibres every time they are washed.
Next
What can you do to reduce microfibres and microplastics?
All of the options would help. You can buy a device like a Guppyfriend or Cora-ball that goes in your washing machine to pick up microfibres so they don't end up in the environment. Clothes can be washed less often, such as only when really dirty. Litter adds to microplastics in the environment, so encourage people not to drop litter.
