  • This Connected article explains how an ancient lake, Foulden Maar was formed by a volcanic eruption 23 million years ago and is very fossil rich. In 2019 it came to the public’s attention when a mining company, which owned the land, had been granted permission to mine there. The scientific community started a campaign against this proposal.

    Use this article to learn about:

    • the creation of Foulden Maar
    • how fossils form, and what is it that makes the fossils at Foulden Maar so special
    • why mine at Foulden Maar – the economic value of diatomite
    • who are involved in the decisions about the future of the maar (the stakeholders)
    • what could be the future for Foulden Maar.

    This article prompts critical thinking and ends with a call to social action.

    Key nature of science ideas

    Use this article to help explain to your students how scientists:

    • look for reliable evidence
    • consider what other scientists have discovered when making a decision about a situation
    • work within a cultural context where science influences and is also influenced by societal responses.

    Key science ideas

    Some of the key science science ideas and concepts covered include:

    • processes that cause the Earth to change over time
    • the processes that gradually change sediments into rocks also help form fossils
    • fossils are the remains of organisms, or traces of their activities preserved in some manner
    • fossils can help us learn about living organism that were on Earth before there were people
    • some fossil materials have an economic value as they can be used to make products.

    Teacher support material

    Check your school library for the article from the 2020 level 4 Connected journal ‘Feeling the Heat’, 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 three learning activities that support the exploring science aspects of the New Zealand Curriculum:

    • Fossils of food? – students take on the roles of various stakeholders with an extension idea on taking action.
    • Buried treasure – understanding and learning from fossils, ending with creating a job description for a Foulden Maar palaeontologist.
    • Geopark – students explore what a geopark is and design their own, and then use Minecraft to build a model.

    In Fossil correlation students date fossils from one site by matching them to fossils already dated somewhere else.

    A geopark is a defined area of international geological significance that tells the story of how the geology and landscape have shaped the lives of its inhabitants, be they people, animals or plants. It is a new UNESCO designation. The Waitaki Whitestone Geopark in the South Island is seeking to be the first designated geopark in Oceania.
