FOCUS
OUTCOME:
9.4.2:
Identify data sources, plan and choose equipment or resources to
perform a first-hand investigation using appropriate materials to
identify microbes in food or in water.
TASK:
To design and carry out an experiment that investigates
the presence of microorganisms in a variety of water samples, and to relate
the incidence of these to human influence.
You
will need to present a comprehensive report for your investigation, which must
include:
- An introductory
information section which collates relevant
information about the broad range of microorganisms present in water, and
summarises the experiment that is carried out
- Aims, hypotheses and
equipment
- Methods which clearly
indicate controls, variables to be controlled, and safe handling of
materials
- Results which include a
variety of pictorial representations
- Discussion of the results
obtained, with a view to identify trends and patterns, as well as
contradictions; make and justify generalizations; evaluate the method used
and offer modifications to the procedures
- Conclusions of the
practical with a plausible justification
- References
Further Information about the Task:

graphs, photographs
- Discussion
addresses the key findings of your investigation's results. In
separate paragraphs, your discussion could function to:
- state what the results indicate
- make inferences about what the results
might mean
- state the implications of your findings (as in
how it might have an
effect in certain examples)
- offer any links between various facts discovered
- address any questions posed
- evaluate identify the shortcomings of the
practical's methods or
findings
- make recommendations as to improvements for the
practical
- Conclusion
briefly summarizes the study, usually referring to the
Hypothesis and whether it was supported or rejected, and a reason
for that outcome.
- References
all resources used should be correctly cited in this section,
including the author, date of publication, title of publication or
article, publisher's details and proposed pages.
