21 Day Challenge 2023 Term 3

A thriving ocean for future generations

What is the 21 Day Challenge?

Young Ocean Explorers 21 day challenge is an integrated curriculum teaching resource that links to the New Zealand Curriculum at levels 1–4, but can be adapted for use at various levels.

  • 21 Days of learning, thinking, and creating to engage and empower students to care for waterways in their local rohe (area). 

  • Each lesson will need about 60 mins - kaiako (teachers) can pick and choose to suit the time  available, and there are many ideas for extension to delve deeper. Each lesson can be integrated across curriculum areas.

  • The complimentary Teachers site and a student site can be used alongside the lessons.



  • To encourage an increased knowledge of Aotearoa’s precious waterways - moana, awa, roto (ocean, rivers, lakes) and how they are linked.

  • To build an understanding of the importance of these waterways to many people in various ways, and the importance for the creatures that live in and around those waterways.

  • To think about kaitiakitanga and caring for our local environment. 

The Teacher site has everything teachers need - a link to the lesson plan overview, and a link to the student site. There is also a daily link to each lesson plan which they will get access to as the challenge progresses.
