Trees, seas and soil
This Connected article starts with the question "What kind of sink can't be used to wash the dishes but can be grown in your garden?" The answer – carbon sinks.
Connected article: Trees, seas and soil
An article in the 2020 level 3 Connected journal ‘Kaitiakitanga’ published by the Ministry of Education, New Zealand.
Use this article and the teacher support resources to discover how different processes combine to affect the balance of carbon in the Earth’s atmosphere. The increasing levels of carbon dioxide (CO2) in the atmosphere is having a huge effect on climate. Carbon is a finite resource and understanding the impact humans have had on the Earth will help us to take actions to help reduce carbon losses to the atmosphere.
Carbon sinks, in the form of forests, the ocean and soils, could help to balance the carbon levels in the atmosphere. However, each form has its own complicating factors.
Southern Ocean carbon sink
Dr Sara Mikaloff-Fletcher, an atmospheric modeller at NIWA, describes the role of the Southern Ocean in taking up carbon dioxide from the atmosphere. Some computer models suggest that this carbon sink is slowing, which might accelerate climate change. The Argo project is providing data to test this model.
Key science ideas
Key science ideas about carbon are covered in this article, focusing on:
How carbon can move from from place to place – in a non-circular carbon cycle.
How the chemical properties of carbon – via a range of processes and chemical changes – enable it to pass between living and non-living systems on Earth.
Some processes are slow – over millions of years, while others happen much more quickly.
We can use what we know about the way carbon moves between these systems to take action to reduce the amount of carbon dioxide moving into the atmosphere.

2020 Connected Level 3: Kaitiakitanga
The cover of the 2020 level 3 Connected journal ‘Kaitiakitanga’ published by the Ministry of Education, New Zealand. This issue includes the articles Life in Aotearoa New Zealand, Raʻui: Giving it back to the Gods, Te tapa ingoa, and Trees, seas and soil.
The teacher support material (TSM) can be downloaded from Tāhūrangi (Word and PDF files available).
There are two learning activities that support the exploring science aspects of the New Zealand Curriculum – remember these activities can be adapted to support your students’ interests and learning needs.
My place in the carbon cycle – uses the carbon cycle interactive diagram to deepen the students’ understanding about carbon and the carbon cycle.
Sink or source? – uses a carbon footprint calculator for schools.

Activity ideas
The following activities can help students deepen their understanding of the importance of carbon for our planet .
Carbon cycle – three-level reading guide – read about the carbon cycle using a three-level reading guide.
Carbon dioxide emissions calculator – use this online calculator to calculate and compare the amount of CO2 produced by different energy sources.
Carbon cycle quiz – use the interactive carbon cycle diagram to explore the global carbon cycle and to answer questions in an online or paper-based quiz.
Climate change
The article Our atmosphere and climate – introduction has links to resources that inform students (and the general public) about the state of New Zealand’s climate.
Climate change resources – planning pathways provides pedagogical advice and links to the New Zealand Curriculum. It includes an interactive planner that groups Hub resources into key science and teaching concepts.
