What makes a Good Science
Extended essay?
•
A good research question which allows you to
design and carry out an experiment.
•
An experiment which generates enough data
for meaningful statistical analysis
Animal Experimentation
Guide
•Designing any experiment that inflicts harm(including
stress) or pain on any animal is PROHIBITED
•Designing any experiment that involves an exchange of
bodily fluids (that includes saliva) is PROHIBITED
•Any experiment involving humans must be with their
written permission
•Any Experiment involving microorganisms must avoid
incubation at or near human body temperature
Structure of the Essay
Title page
Abstract
Contents page
Introduction
Investigation/body (development/methods/results)
Conclusion
References and bibliography
Appendices (Raw data should be here)
Length of the Essay
•
The essay should not exceed 4000 words.
•
The word limit does not include:
• the abstract
• acknowledgments
• the contents page
• maps, charts, diagrams, annotated illustrations and tables
• equations, formulas and calculations
• citations/references (whether parenthetical or numbered)
• footnotes or endnotes
• the bibliography
• appendices
Science Specific Overview
•
There are separate sections for Biology,
Chemistry, Physics, Environmental Systems,
Sport Exercise & Health Science and Design
Technology within the EE guide
•
Read the appropriate section very carefully.
•
There is good advice concerning the Research
Question
Assessment Criteria
•
Read all of the Assessment Criteria carefully
alongside the Subject Specific information
A:Research Question
You need a Science specific research question (ensure that it is
specific to your Science subject)
Include the independent variable(s)
Include specifically the dependent variable
Include the name of any organisms and chemicals involved in
your investigation
Be Specific and clear
State your Research Question clearly
(underlined or bold) at the beginning of your
introduction.
B: Introduction
Context - Clearly explain the scientific theory
behind the Research Question. Include
citations. This is background
information/hypothesis.
Significance - What are you trying to
understand better?
Worth - Why is this worth investigating? What
is the value of this research
C: Investigation
•
How well have you planned your investigation?
•
Include:
•
An explained hypothesis
•
An explanation of how all variable are controlled
•
A list of materials (which can be included in a cited appendix)
•
A clear method which collects enough meaningful data. You should be able to use the data for producing
graphs with standard deviation error bars, and statistical analysis such as t-test, Anova
•
To get the top marks, you need to develop an interesting method, rather than modify a standard procedure.
•
Additionally I suggest that you include information on a trial experiment to determine suitable variations of the
independent variable, and to confirm that you can collect data.
D: Knowledge and
Understanding
Academic Context - compare your data to data from
other investigations in this field with citations (in the
conclusion).
Knowledge
It must be clear that you understand the information
within your essay and that your provide citations.
Avoid jargon, if jargon must be used ensure that it is
explained.
E: Reasoned Argument
Avoid investigating too many independent variables - one or two is best.
Ensure the argument is presented as:
•
Introduction of the problem
•
Experimental procedure
•
Present Data (Raw data can be in a cited appendix)
•
Present graphs/statistical analysis
•
Analyse your data and compare it to literature
•
Conclusion
Refer to the Research Question at all stages of the EE
F: Analytical and evaluative skills I
Raw data must be presented (but if large amounts are generated
should be in an appendix)
Processed data tables should be in the body of the EE
Graphs (including error bars) should be presented in the body of
the EE
Consider data analysis such as ANOVA or t-tests (ensure that
your data meets the required conditions. Always state the null
hypothesis and alternative hypotheses - calculations can be in an
appendix)
F: Analytical and evaluative skills II
•Analysis and Conclusion must be based on
the data collected.
•Analysis should attempt to answer the
research question
•Errors and uncertainties arising from
methodology, instruments and/or techniques
should be analysed and evaluated
G: Appropriate language
•Terminology must be used correctly
•Avoid Excessive jargon
•Jargon should be explained
•Maintain a consistent linguistic style
H: Conclusion
State a clear conclusion based on the data
collected and your analysis
Identify unresolved questions/issues
I: Formal Presentation I
•
•
More than 4000 word means no points
Science investigations “often result in large
quantities of raw data. Large tables of raw data
are best included in an appendix. Processed
data fundamental to the research question
should be included in the body of the essay.”
(IBO)
I: Formal Presentation II
•
You must include the following:
• title page
•
table of contents
•
page numbers
•
illustrative material with captions & citations
•
quotations
•
documentation (including references, citations and bibliography)
•
appendices
J: Abstract
More than 300 word means 0
The abstract requires three components:
•
A clear statement of the research question
•
A clear summary of the procedure
•
A clear summary of the conclusion
K: holistic judgement
Three things are considered:
• Intellectual initiative (The EE should not be an
IA)
• Depth of understanding
• Insight
Appendices, footnotes & Endnotes
“Appendices, footnotes and endnotes are not an
essential section of the extended essay and examiners
are not required to read them, so care should be taken
to include all information of direct relevance to the
analysis and argument in the main body of the essay. An
essay that attempts to evade the word limit by including
important material in notes or appendices risks losing
marks under several criteria. Unless considered essential,
complete lists of raw data should not be included in the
extended essay. Students should not constantly refer to
material presented in an appendix as this may disrupt the
continuity of the essay.”
Experiment or Research
Essay?
•
Both are possible but experiment essays are
more likely to be successful.
•
If you do a research essay, you must still
analyse data and produce graphs.
•
If you do a research essay, you will need to
find something new and interesting that the
original research did not.
