    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. 

    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. 

    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.

    Check your school library for the article from the 2020 level 3 Connected journal ‘Kaitiakitanga’, download it as a Google slide presentation or order it from the Ministry of Education.

    The teacher support material (TSM) can be downloaded from TKI (Word and PDF files available, click on 'Look inside this issue'). 

    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.

    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.

    Learn more about the impacts of climate change by browsing the wide range of content under the climate change topic.
