Dugong dilemma: assessment (L7734)
Description Assess your ability to test a hypothesis by investigating data and using scientific models. Select likely hypotheses for the decrease in a dugong population. Investigate the living things present in a coastal marine habitat, and use a food web to understand the relationships between different animals. Model the effects of human activity and changes in population on selected marine life. For example, observe the effects of an increase in recreational fishing on the dugong population. Record data in a notebook. Select the most likely hypothesis for declining dugong numbers based on the evidence collected, and summarise your reasons for selecting this hypothesis.
