The main current in the Southern Ocean is the Antarctic Circumpolar Current (ACC), which flows from west to east, all the way around Antarctica. The ACC is the biggest current in the world and ...
During winter, the average temperature in the South Pole is -60C, but in the North Pole it is -30C. Why is there such a difference? Three factors come together, resulting in the cold world we ...
A glacier is a large quantity of ice formed from snow that has accumulated and been compacted over a long period of time. About 70% of the Earth’s freshwater resource is stored in glacial ice ...

The rocky shore is a popular topic in primary school science. Below are some Science Learning Hub resources for primary teachers related to the rocky shore in the Living World strand of the New ...
This animation shows how snow on the ground is rounded and compacted, sealing off pores between the grains, trapping atmospheric gases. Snow that survives one melting season is called firn ...
Dr Katja Riedel of NIWA explains how ice cores are dated. The researchers often rely on events like volcanic eruptions to determine how old the ice is.
Dr Katja Riedel of NIWA talks about how snow turns into ice and how the air gets trapped in the ice during this process.
Dr Candida Savage explains the clues she collects in estuaries and fiords, to understand how changes in land use affect these environments.
Wetland ecosystems hold significant environmental and cultural value in Aotearoa. Learning about these values and the steps we can take to protect and uphold the values are suited to inquiry ...
