Please read the 3rd paragraph of the Introduction article and comment on what are the characteristics.

There should be about 1 characteristics that you and your team mates can identify easily.

Promote thinking and discussion

3. Mention past attempts to solve the research problem or to answer the research question.

As this is not a full scale thesis but a science research, the review of literature is out of place in the Introduction section of a research paper. However, it is appropriate to indicate any earlier relevant research and clarify how your research differs from those attempts. The differences can be simple: you may have repeated the same set of experiments but with a different organism, or elaborated (involving perhaps more sophisticated or advanced analytical instruments) the study with a much larger and diverse sample, or a widely different geographical setting.

Here is an example:

• The motivation for using the Odonata order as indicators of Ecological health of freshwater sources stems from an observation made by Murphy (1997) regarding the distribution of three species of Prodasineura within Singapore’s Central Catchment Area. From his observations, each of the three species had totally different habitats, demonstrating that odonates can be used as a bio-indicator for eco-monitoring.

• It has been found that each type of water body has a characteristic odonate species assemblage (McPeek, 2008). McPeek (2008) further elaborated that oxygen availability and fish predators have limited some species to smaller streams while large, active dragonflies are relegated to ponds and lakes, where fish cannot colonize.

• In a study by Silva et al. (2010) at Turvo Sujo River in Southeastern Brazil, they tested the use of adult odonate individual species and community assemblage measures to evaluate the effect of riparian vegetation cut-off and sewerage discharges. They found that physiochemical parameters of water as well as odonate abundance and assemblages are affected by possible water pollution due to municipal sewerage discharges.

• Although this is a recognized fact, there are no detailed studies on each individual species in light of these observations, in particular in Singapore context.

Get into your project groups and discuss how your 3rd paragraph should look like.
