Plastic bird-feeder

Out of the 13 billion plastic bottles used in the UK each year, only 7 billion are recycled. To be a plastic hero, we need to reduce the amount of plastic that we use and stop it from ever becoming waste. This activity involves rethinking how a single-use plastic bottle can have another life as a bird feeder to help nature in your garden.

Overview

We live in a world full of plastic. As we learn to redefine our relationship with this material, we can find inspiration in the 6 Rs: recycle, reuse, reduce, repair, refuse, and redesign.

Many people are great recyclers but find it challenging to implement the other Rs, which have a greater impact on reducing plastic pollution.

This activity shows you step by step how to rethink a single-use plastic bottle can be used to make your own plastic bird feeder. Win-win for you and the environment.

Activity steps

Prepare your workspace by clearing your desk, laying newspaper down, and get all of your materials out.
Wash the plastic bottle out with water and let it dry out.
Measure about 10cm up the bottle and draw a small circle. It needs to be about the same size as the handle of your wooden spoon.
On the opposite side draw a larger circle, about the size of a big coin. The bottoms of the circles need to be at the same height.
Squeeze the bottle together and carefully cut the circle out. Do not try to poke a hole in the bottle.
Put the wooden spoons into the bottles. The big end of the spoon needs to go snugly in the big hole.
Put the lid on the bottle.
Use string to make a loop so you can hang the bird-feeder.
In a tray at home, fill the bottle with seeds. The tray will stop the seeds from making a mess.
What do your garden birds think of their new feeder? We’d love to see a photo of them enjoying it. Don’t forget to tag @commonseas when sharing anything online (and use the hashtag #SeaChampions), so we know where to look. Thank you!

Reflection

Time to consider the advantages and disadvantages of plastic as a material. Reflect by discussing the following questions with a parent or friend.

Who might want to use a bird feeder like this?
Why is plastic a good material for a bird feeder?
What is good about your product?
What could you to do make your product better?
Why is it important to rethink plastic waste?

Further ideas

You can explore a full unit looking at design and plastics with the Ocean Plastics Design and Technology lessons for ages 11 to 14. For younger students have a look at the lesson for ages 5 to 7, What can I do? and for ages 7 to 11, try the design-focused lessons Design Technology – The plastics problem and Design Technology – The plastics solution.

Safety guidance

This activity involves cutting through plastic and can, therefore, be quite tricky so adult supervision and the use of child-appropriate tools such as safety scissors is advised.
If you are posting work on social media, this should be done via a parent, guardian or school account for children under the age of 13. Children over the age of 13 should still be supervised by an adult. Check out the Thinkuknow website for more guidance on online safety.

Over 300 million tonnes of plastics are produced worldwide annually. This is nearly the weight of the entire human population!

From all the discarded plastic, around 8 million tonnes end up in our oceans, making plastic the greatest component of marine litter. Wind and light help degrade this plastic debris over time, transforming it into microplastics. These fragments smaller than 5mm are everywhere in the global ocean. Plastic debris affects wildlife as it causes entanglement, ingestion, and habitat alteration. Fish, crustaceans, and other animals ingest microplastics, which reduces their energy intake and body mass while having adverse health outcomes. This has also major implications for humans, from healthcare to economic activity.

Waste hierarchy definitions

Recycle: take an existing product that has become waste and reprocess the material to use in a new product. For example, putting a plastic milk bottle into your recycling bin, so that it can be turned into a new milk bottle.

Reuse: take an existing product that could become waste and use the item or parts of it for the same or another purpose, without processing it. For example, reusing a plastic shopping bag for multiple shopping trips.

Reduce: minimise the amount of energy and materials used to make a product. For example, reducing the amount of plastic packaging for a food item.

Refuse: not using or buying a product if you do not need it or you do not think it is sustainable. For example, refusing single-use coffee cups and using your own cup, or asking not to have a straw for your drink.

Repair: when a product breaks or stops working properly, choosing to try to fix it, rather than throwing it away. For example, many electronics items can be repaired reducing waste and saving money.

Redesign: often called rethink, this involves redesigning a product to make it more environmentally friendly or finding a new and different use for an item that might be thrown away. For example, turning a plastic bottle into a bird feeder.

So, in the long term we need to change how we relate to plastic through the 6 Rs: recycle, reuse, reduce, repair, refuse, and redesign.

This activity is just one idea of how you can contribute to rethinking plastic and reducing the impact it has on the environment.
