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 ...
Professor Kate McGrath’s team of researchers at the MacDiarmid Institute are trying to replicate the way in which pāua (Haliotis iris) lay down their shell material. Pāua shell is an arrangement ...
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 ...
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 ...
Be part of a worldwide movement and use Global Earth Challenge to submit or classify photos to help our planet’s environment and human health. Global Earth Challenge is a citizen science campaign ...
This citizen science project wants your assistance to extract information from various climate scientific graphics to help combat misinformation and support scientific communication. Using this ...
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 Aotearoa New Zealand every year. Canterbury’s 7.1 and Kaikōura's 7.8 magnitude earthquakes and subsequent aftershocks show the constant threat ...
As science and technology advance, ethical issues are brought to the fore not only for scientists and technologists but also for the general public. The New Zealand Curriculum (NZC) reflects this ...
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 ...
To make a material comparable to a natural biomineral involves using known techniques and procedures that hope to capture the essential elements of the natural system. In this video clip ...
Carefully controlling the pH of the hydrogel and soaking it in solutions containing calcium and carbonate ions can initiate the mineralisation process. Professor Kate McGrath, of the MacDiarmid ...
