• TLF-IDA005123

In this activity students investigate how ocean acidification may affect organisms with shells or exoskeletons made of calcium carbonate, such as oysters, clams, sea snails and coral. Students develop and conduct an experiment to test the effect of carbonated water on calcium carbonate and then analyse the results and produce ...

In this series of activities students investigate how carbon dioxide affects the pH of water, and how carbon dioxide may affect fish and other marine species. They then brainstorm changes that can be made to reduce human impact on reefs, research carbon capture and storage technology, and design a device to remove carbon ...

This activity invites students to explore how the pH of a solution dictates whether carbon is present in the form needed to make seashells. The activity includes a list of tools and materials required, what to do and notice, an explanation for the underlying science of what students observe and suggestions for further activities.

This program deals with a range of human impacts on the Great Barrier Reef. Herbicides from land runoff have been traced to algae and sea grasses in river mouths and coastal zones along the Great Barrier Reef. Effects include retardation of photosynthesis and growth of corals. Other pressures on the reef include high water ...
