This unit plan shows how teacher Dianne Christenson used the online citizen science (OCS) project The Plastic Tide as part of a year 2–4 unit to develop students’ science capabilities in a unit on sustainability. Although this OCS project has been completed, several similar projects exist – see Litterati and Litter Intelligence. Read more about Dianne’s experiences implementing the unit in this case study.
In this unit, students did a lot of hands-on learning about litter by doing regular lunchbox audits and LittaTrap audits, sorting beach samples and using the OCS project The Plastic Tide. The core focus of the unit was developing the science capabilities ‘Gather and interpret data’ and ‘Engage with science’.
Through the kaitiakitanga unit, students were able to connect their regular stream monitoring work with some big questions about the amount of litter found locally and then globally and to reflect on what changes are needed to reduce litter.

The Science Learning Hub worked with the Office of the Prime Minister’s Chief Science Advisor on the article Rethinking plastics. This includes the interactive timeline Plastics: innovations and impacts – an exploration of plastic technology, impacts and initiatives. Plastic is a wicked problem that offers a rich context for learning – our planning pathway will help you get started.
This article curates a wide range of Science Learning Hub resources for primary teachers related to recycling and biodegradability in the Material World strand of the New Zealand Curriculum.
Find out about the Ocean Plastic Simulator – an interactive computer tool that shows where virtual plastic is likely to end up when it is dropped in the ocean.
Oceans of rubbish provides insight into the breadth of the pollution problem in our seas.
Read the Connected article Down the drain to see how students in Petone, Lower Hutt, took action to prevent rubbish from entering their local marine environment. They also used LittaTraps.
Use these activities with your students to further investigate litter and the impact it has on our environment:
- What happens to our plastic bottles?
- Plastic – reuse, recycle or rubbish game
- DIY plastic recycling plant
- Biodegradability experiment
- Waste – a growing challenge!
The Plastic Tide citizen science project has now finished, but many relevant learnings can still be taken from it.
See the Royal Society Te Apārangi website for the report Plastics in the Environment and other resources.
Find out more about the LittaTrap and how it works.
