This lesson incorporates clips from Blue The Film as learning inspiration. Students investigate what types of plastics are found in a typical lunchbox. They explore how long these plastic items take to breakdown if they are not reused or recycled. Students are then asked to compare and contrast single use plastics to reusable plastic items. Finally, students take part in an eco-cooking demonstration by creating a Great Pacific Garbage Patch Soup, reflecting on the impact that plastics have on our oceans.
- recognise the different types of plastics that are found in lunchboxes and where they may end up if they are not reused or recycled.
- identify some of the different types of plastic found in a typical lunchbox
- identify some of the ways we can reuse plastic
- identify what the Great Pacific Garbage Patch is and where it came from
- articulate how our everyday choices impact on the Great Pacific Garbage Patch
- articulate how we can choose to use plastic in a more sustainable way
- contribute to class-wide discussions
- follow and participate in a class-wide demonstration.

Australian Curriculum content descriptions:
Year 3 Science:
- Science knowledge helps people to understand the effect of their actions (ACSHE051)
Year 4 Science:
- Science knowledge helps people to understand the effect of their actions (ACSHE062)
- Natural and processed materials have a range of physical properties that can influence their use (ACSSU074)
Syllabus outcomes: ST2-11LW, ST2-13MW.
General capabilities: Critical and Creative Thinking.
Cross-curriculum priority: Sustainability OI.2, OI.9.
Relevant parts of Year 3 Science achievement standards: Students describe how they can use science investigations to respond to questions.
Relevant parts of Year 4 Science achievement standards: Students apply the observable properties of materials to explain how objects and materials can be used. They identify when science is used to understand the effect of their actions.
Unit of work: Blue The Film: Inquiry – Years 3 & 4.
Time required: 80 mins
Level of teacher scaffolding: High – lead activities and discussions.
- Student Worksheet – one copy per student
- Device capable of presenting a website to the class
- Cut out small squares of recycled/scrap paper
- Great Pacific Garbage Patch Soup – Instruction
You will also need:
- 10 – 12 different types of lunchbox items, including plastics wrappers (biscuit and chip packets), plastic cling wrap, straws, recyclable juice boxes, fruit (apple/banana) and a lunch box for the longest lunch demonstration. Put the objects into the lunchbox to represent a student lunchbox.
- Equipment needed for the eco cooking session: large bowl, wooden spoons, water, two pairs of scissors, plastic items, ladle and small bowls.
This lesson is designed to build students’ competencies in the following skills:
- Problem solving
Blue is a feature documentary film charting the drastic decline in the health of our oceans. With more than half of all marine life lost and the expansion of the industrialization of the seas, the film sets out the challenges we are facing and the opportunities for positive change. Blue changes the way we think about our liquid world and inspires the audience to action. Find out how to screen or download the film here. Along with the film is an ambitious global campaign to create advocacy and behaviour change through the #oceanguardian movement. To become an ocean guardian, see the website.
