The graph, below,
illustrates the temperature
changes at willis island in the
coral sea from 1939-2001. the
researchers proposed the
hypothesis:
at willis island in the coral sea, coral
bleaching occurred from 1953-1966.
1. discuss whether the data
represented in the graph
supports this hypothesis.
2.outline an experiment that researchers could do to test whether corals on a reef are currently bleaching.
your answer should include reference to the control of variables and the collection of quantitative results.
