Limestone is an unusual rock in that it fizzes when dilute acid is placed on its surface. It is the presence of calcium carbonate that is responsible for this. The calcium carbonate content of ...
Calcium carbonate is the principal mineral component of limestone. Its chemical and physical properties lie behind the modern-day uses of limestone as well as the unique limestone landscapes of ...
The haukāinga (local residents) of the Rotorua area – Te Arawa, Tūhourangi and Ngāti Wāhiao – have lived in this highly active geothermal region for generations. The unique geology of the area ...
In this activity, students view the interactive Calcination – lime from limestone, which shows the industrial processing of limestone into lime, and use the information to complete a matching ...
In this activity, students investigate some of the physical, chemical and physiological properties of carbon dioxide gas. In addition, a model demonstrating the amount of carbon dioxide in the ...
In this activity, students view the interactive Limestone’s secrets revealed and then answer graded sets of questions based on the content of the video clips from the interactive. By the end of ...
The Planet Four online citizen science project is designed to assist planetary scientists to identify and measure features on the surface of Mars that don’t exist on Earth. Help is needed to ...

In this recorded professional learning session, Lyn Rogers and guest Aliki Weststrate from GNS Science explore some of the science involved in building our understandings of natural hazards ...
About 14,000 earthquakes are recorded in and around New Zealand every year. Canterbury’s 7.1 and Kaikōura's 7.8 magnitude earthquakes and subsequent aftershocks show the constant threat ...
Children’s involvement in science is increased when they have an opportunity to make decisions about science-based issues that have consequences for their lives. It’s bringing science into the ...
Professor Kate McGrath, of the MacDiarmid Institute, explains the process by which organisms that have hard structures such as bone and shell deposit mineral-rich hard tissues. The process is ...
Rotorua is world famous for its geothermal features. For generations, local Māori used the hot pools with little impact on the natural system. As Rotorua’s population grew, unsustainable amounts ...
In this video, educator Angela Schipper demonstrates how to build a model of an aquifer – a layer of rock or other material that carries water underground. This is an excellent activity that ...
