Microplastics
to CARE about
In the race towards exams, it can be easy to forget the other goals of science education:
scientific literacy (science in life) and STE(A)M careers (science in society).
CONNECT is an EC-funded project offering a new kind of resource, called a Science Action.
It’s a set of activities to integrate a real-life challenge into an existing topic and it ticks lots of boxes:
Introduction
See more about Microplastic Science Action
Engage with a real-life challenge
Know and apply a science concept
Practice an enquiry skill
Understand how science affects their world
Interact with a scientist or engineer ( CONNECT Platform)
Talk about science with family-members
MICROPLASTICS in compliance with
Introduction
Plastic waste is killing our oceans.
If we don’t act
now, by 2050
there could be
more plastic
than fish.
But it’s not just the
plastic we can see.
Plastic breaks down
into tiny bits –
microplastics – that
could be an even
bigger problem.
Click for video
Microplastics get eaten by fish…
…and then by us.
Why might your body contain microplastics?
Your engineer
friend
I want to find a way to
help with the plastic
problem.
Why doesn’t this method remove microplastics?
We’ve invented a way of
removing large pieces of
plastic from the oceans,
but it doesn’t work for
microplastics.
THE MICROPLASTIC CHALLENGE
Calling designers, engineers
and scientists.
Can you invent a way to stop
microplastics polluting our
oceans?
The winner will get funding
to develop their idea.
Enter your invention
Let’s enter this
competition.
Find out if you could live plastic-free
Home task
But I’m not sure
this is possible –
what do you think?
Of course, the best way to
stop microplastic pollution
is to stop throwing away
plastic.
Microplastics
to KNOW about
• The planet is swimming in plastic waste. It’s killing animals and it
may be damaging human health too.
• 40% of plastic is thrown away after one use. This ‘single-use
plastic’ ends up in landfills and oceans. It decays very slowly. So, it
stays in the environment for hundreds of years as it breaks down
into smaller and smaller bits - microplastics. These end up in our
water, our food and even the air we breathe.
• In March 2022, world leaders agreed a treaty to reduce plastic
waste. The next step might be that the UK Governments bans
single-use plastic.
• Could you remove single-use plastic from your home?
Can you live plastic free?
Tasks
1. Identify single-use plastics in your home
• Use the sheet Single-use plastics.
• Tick the boxes for the uses in your household.
• Write down other single-use plastics you use into the blank boxes.
• Hint: look at the plastic items in your bin.
2. Work out how to remove single-use plastics
• Use the sheet Single-use plastics.
• For each you ticked, write down a change you can make to remove the single-use plastic.
• If you need help view this page: tinyurl.com/ywcebdy8.
3. Make a pledge
• Decide together to use one, three or five of the changes now.
• Draw a star on the sheet in the boxes of the one/s you choose.
• Discuss together: Do you think you could remove all single-use plastics from your home?

If you want to learn more about plastic waste
here are some useful videos:
We use
clingfilm.
We buy
drinks in
plastic
bottles.
Our bread
comes in a
plastic bag.
Our bathroom
products are in
plastic
containers.
We buy
takeaways/ready
meals in plastic
containers.
Our fruit and
veg comes in
plastic
packaging.
We use
disposable
razors.
We chew
gum (yes it
contains
plastic!)
We use
disposable
plastic pens.
Can you live plastic free?
Microplastics
to DO something about
Remember the challenge:
How can we stop microplastic
waste polluting our oceans?
Did you know?
Most of the clothes
you wear are made
of plastic.
Click to zoom
73% Polyester
27% Nylon
Every time you wash
clothes in your machine,
they shed hundreds of
thousands of microplastics.

The water

ocean
clothes
Let’s invent a way to stop microplastics escaping
from washing machines.
Your ideas to stop microplastics escaping
The challenge: microplastics are tiny
What makes some
microplastics hard to
capture is that they’re
very small.
Let’s see how small…
1 cm
Largest microplastics
1 mm
Grain of rice
What is the length of the largest microplastics?
Click for
simulation
Objects 0.1 mm in size are
the smallest you can see
with just your eyes.

Medium sized
microplastics

To see objects smaller
than 0.1 mm, you need a
microscope.

We use a unit called a
micrometre (µm) to measure
lengths this small.
How many micrometres are in 1 mm?

Mitochondrion
There are 1000 µm in 1

So, 1 µm = 0.001 mm
Check your understanding of size and scale (SS1)
Task
Task
We should design a filter
that fits into a washing
machine and removes all
the microplastics.
To enter the competition,
let’s submit a design and
explain how it works.

2. Answer these questions on your own:
1. Put these objects in order of size, smallest first: bacteria, amoeba, antibody, skin cell.
2. If you lined up bacteria end-to-end, how many would fit inside a skin cell?
3. How big is an amoeba in mm?
4. True or false: The smallest microplastics are 0.001 mm.
5. Noah says ‘you can see if there are microplastics in water with your eyes.’ Do you agree? Give a reason for your answer.
Can see just using your eyes
Can see using a microscope
What to do:
1. Discuss what this diagram shows with a partner:
µm is short for micrometre
1 µm = 0.001 mm Each unit is 10 times
(10x) bigger than the
previous unit
Competition entry SS2
Clothes go
in the drum.
It then fills
with water.
After the clothes are washed,
the water leaves this way.
The water eventually
ends up in the ocean.
2. Describe your invention in detail.
1. Introduce your invention in a sentence: What is it and what job does it do?
4. Give reasons why your invention should win.
3. Explain how your invention works.

Editor's Notes

  1. Change to just plastics being eaten by animals
  2. Add engineer again to the side – there is this great challenge – let’s enter it.
  3. Remove if you have a scientist
  4. Students discuss in groups and feedback their idea of how to do this. They also have a beaker of water with glitter of different sizes in. They will say filtering. Ask them what they need to know about the microplastics before – their size. This leads onto the next section.
  5. Show simulation first. Just show a ruler – 1 mm. Show microplastic size against a ruler.
  6. The answer should include the following: Design of filter: made of plastic because paper would break down in the water Holes need to be smaller than smallest microplastic (1 um). Placement of filter: In a place that water containing microplastics flows through. If it is outside the machine, it is easier to empty. How it works: Water and dissolved substances are small enough to pass through the holes in the filter, but microplastics are too large so stay in the filter. The filter would have to be emptied now and then to remove the microplastics. A good place to put them would be in the rubbish bin, so they would be less likely to enter the water supply.
