A Waste Free World With Sam Bentley

Teacher notes

Plastic is an amazing material because it's durable and used for many things, but its waste is found in every part of our world from Mount Everest to the deep sea, and it can take a long time to break down. We need to address plastic pollution. Luckily there are things we can do and some amazing technological innovations.

Supports learning about plastic pollution, materials, and oceans and rivers .

These teacher notes outline activities for you to try with your class and get pupils thinking about environmental challenges. The Blue Peter Earthshot competition is now closed for entries, for more info head over to the Blue Peter website.

Classroom ideas

Let鈥檚 talk about plastic pollution

Help pupils join the conversation by discussing and creating your own glossary of key terms together:

  • Chemicals 鈥 a substance or mix of substances that has been prepared, often artificially.

  • Innovation - new ideas that often offer a breakthrough and new direction.

  • Ocean Gyres - a large system of rotating ocean currents.

  • Plastic - a wide range of synthetic materials that can be moulded into a variety of shapes.

  • Sustain - support or keep something going.

The Great Pacific Garbage Patch

A million tonnes of plastic reach the oceans from our rivers every year. Ocean currents carry it into vast gyres, one of which has been labelled the Great Pacific Garbage Patch (GPGP): located halfway between Hawaii and California, this collection of floating garbage is mostly plastic, and it covers an area around 1.6 million square kilometres. Pupils could use digital mapping to locate and label this gyre and map its extent.

Although the GPGD looks shocking, it is reassuring to know that only about 0.3 % of all plastic waste reaches the oceans, the rest ends up recycled or in landfill. That means that we are containing most of the waste and it seems achievable to do more. Ask pupils to check out the Great Ocean Clean up, started by Boyen Slat when he was only 18 and report back on the project and what it is achieving. Discuss with pupils how we can all dispose of plastic more carefully to avoid it being washed into rivers and then, into the ocean.

Essentially plastic

Plastic is such a useful material. It is sterile, waterproof, and cheap. It is used to contain medicines and vaccines and is used for life-saving equipment in hospitals. It makes vehicles lighter and keeps food fresh. Look around the classroom and the school and create a list of plastic uses, and ask pupils to sort these into essential, and not essential uses of plastic.

Our personal plastic waste

Ask pupils to guess how much plastic waste they create in a year. The average Brit creates about 77 kilograms of plastic waste a year, according to Hannah Ritchie who believes we could be the first generation to build a truly sustainable planet. Ask pupils how they could reduce their own plastic waste footprint by reducing consumption.

Sustainable seaweed

Packaging made from seaweed that is also edible! The story is an amazing example of human innovation. Ask pupils to work in small groups and imagine they have just discovered this product and to think how they would pitch it to a financial backer. Each group could also take it in turns to be the 鈥榖ackers鈥 asking difficult questions.

Hope into action

Before showing the film, ask pupils to say on a scale of 1 鈥 10 how bad a problem they think plastic pollution is, and, on a scale of 1 鈥 10, how hopeful they feel about finding solutions. Repeat the poll after engaging with the film and some of these ideas. Do pupils feel more hopeful and inspired? Discuss with pupils what approaches make us feel we can take on big problems more easily.
