The toxicity bioassay report

The prac report is to be written as a professional scientific research report.
Begin with the author’s credentials:
The author
ie. your full name (you will list your fellow team members who assisted
in the pracs in the Acknowledgements)
Your position
ie. in this case it will be your student id.
Your place of work
ie. in this case it will be Deakin University, School of Life &
Environmental Sciences
The date
ie. the date the report was completed
NB. In some reports the order of the information above (including the
Acknowledgements and Title of the report) may differ depending on the
requirements of the industry or government office you are working for.
(marks deducted if inaccurate or absent)
ie. a short factual description of the research investigation (no more
than 10 words)
ie. a very short summary of the most important points from the research
findings; purpose, findings, major conclusion/s (in no more than 100 –
200 words; it should be the last section to be written) (5 marks)
The toxicity bioassay report 2
ie. you are literally defining the subject of the report, starting with the
purpose of the research investigation, state the aims and objectives of
the research, and background (ie. putting your research into context eg.
what knowledge exists in this area, the limits or scope of your
investigation), specific hypotheses if applicable and an overview of what
will follow. In other words, why was this study performed? What
knowledge already exists in relation to this subject? What is the specific
purpose of the study? (10 marks)
ie. description of what was carried out (be exact and precise) (5 marks)
ie. the results section summarises the data from the experiments
without discussing their implications. Data should be organised into
graphs, photographs and so on.
Remember than all graphs, tables, photos should be numbered
separately, and referred to in the text by number (eg. Fig 1). All figures
and tables should be labelled and self-explanatory. The title for a figure
appears below the figure, the title for a table appears above the table.
The results section concentrates on trends and differences, not trivial
details. Many researchers complete the results section first when writing
a report. (See Appendix below for further detail re. results)
(35 marks)
ie. this section re-states the research findings only in relation to
emphasizing the interpretation of the data, relating them to existing
theory and knowledge. Speculation is appropriate here as long as it is
acknowledged as speculation. Suggestions for the improvement of
techniques or experimental design can also be included here. You should
be able to explain the logic that was applied to accept or reject your

findings. You can also suggest further experimentation that could clarify
areas of doubt in your results. (40 marks)
(NB. Remember to check the Bioassay Prac 1 notes (Week 2 Cloud
Deakin site) when planning your discussion – there are some important
points listed that you should be considering when writing your report)
Re-affirm your findings in relation to what they definitively show or
indicate. (5 marks)
ie. use the Harvard Style for referencing (& citations throughout the
report) (marks deducted if inaccurate)
ie. acknowledge your research team members who worked with you to
conduct the experiments. (marks deducted if absent)
Eg. the original data set out in a table form
(marks deducted if absent)
At this point in your academic career it is expected that you are able to
produce a professional report that:
1. adheres to all instructions in relation to what is expected in the layout
and content of the report, and
2. has been thoroughly proof read ( meaning that spelling mistakes and
grammatical errors have been removed from the report; and that any
poor sentence structure resulting in a lack of clarity, has been identified
and edited from the final report)

Deductions will be applied only up to a maximum of 25 marks where the final
report is not to a professional standard of presentation.
Setting out your Results section requires a bit of thought. You have a number
of graphs and tables to present. Consider the best way of doing this so that
each is clearly identified.
You can present the results using both normal and probit graphs if you wish (at
the very least probit graphs should be presented).
In addition to the probit graphs, you can also present the results using graphs
generated using the Excel EC50 calculator if you wish. A copy of the Excel EC50
generator can be found in the WEEK 4 Weekly resources folder
