Room 5 students at Motueka South School saw a video about the Great Pacific Garbage Patch and were inspired to take action. There’s a lot of media attention on how plastic is polluting the oceans, and it sometimes seems as if the problem is too big to tackle. These students show that it’s possible to make small changes that lead to big results.

Students could collect a range of packaging that is used for food products.
The packaging could be analysed as follows:
- Identify the materials that the packaging is made from
- How have the materials been manipulated (for example, cut into a shape, joined, printed on) to make the packaging?
- Explore other materials in your classroom that have been used to make products – how have these materials been manipulated to make the product?
- What are the performance properties of the materials used for the food packaging (refer to such things as strength, water resistance, flexibility, permeability, transparency, and colour) Why have these materials been chosen for this product?
- What are the lifecycle of these materials?
- What ideas do you have for making the packaging more environmentally friendly?
