Teachers Information

This product is part of our legacy project.

We are way behind and don't have enough sponship money and so have asked schools to chip in via the power point licence to pay schools for TRS days.

You know it takes two days to finish one power point.  That's $800 TRS for each power point  - so multiply that by 90 and that's $72,000 in TRS days.

T 074 Recall the different types of reef structure (e.g. fringing, platform, ribbon, atolls, coral cays) 

T 075 Recognise the zonation within a reef cross-section (e.g. reef slope, reef crest/rim, lagoon/back reef).

T 078 Identify the anatomy of a typical reef-forming hard coral including skeleton, corallite, coelenteron, coral polyp, tentacles, nematocyst, mouth and zooxanthellae 

T 079 Recall that the limestone skeleton of a coral is built when calcium ions [Ca2+] combine with carbonate ions [CO32–]

T 087 Explain that habitat complexity (rugosity), established by corals, influences diversity of other species 

T 088 Explain connectivity between ecosystems and the role this plays in species replenishment 

T 089 Understand that fish life cycles are integrated within a variety of habitats including reef and estuarine systems

T 090 Describe how fish, particularly herbivore populations, benefit coral reefs 

T 091 Identify ecological tipping points and how this applies to coral reefs 

T 092 Describe hysteresis and how this applies to the concept of reef resilience 

T 093 Assess the diversity of a reef system using a measure that could include (but is not limited to) line intercept transects, quadrats and fish counts using underwater video survey techniques, benthic surveys, invertebrate counts and rugosity measurements 

T 094 Analyse reef diversity data, using an index, to determine rank abundance 

T 095 Interpret, with reference to regional trends, how coral cover has changed on a reef over time 

T 096 Recognise that some of the factors that reduce coral cover  (e.g. crown-of-thorns) are directly linked to water quality 

T 097 Understand that the processes in this sub-topic interact to have an overall net effect, i.e. they do not occur in isolation. 

T 098 Examine the concept of connectivity in a habitat by investigating the impact of water quality on reef health.
