- Title
- Titles should be precise and description.
Generally, they will include scientific jargon. Avoid cute titles.

Don't Pop Your Smile |
Evaluation of Bob's Cola as a cause of Tooth Enamel
Damage |
- Research Question or Problem
- The research question should be specific and
testable.
|
Will drinking lots of pop ruin your smile? |
Can normal consumption of Bob's Cola damage tooth enamel? |
- Hypothesis
- A hypothesis Is not an educated guess. It is a
proposal for answering the research question which states the basis
for the proposal along with criterion for testing.
If-then statements are
an excellent form for the proposal.
A hypothesis should generally start with a brief
discussion of the basis for the proposal. This should include references to
a literature search, previous observations, or expert opinion.
A well written hypothesis will state the independent
and dependent variables along with possible lurking variable, which need to
be controlled. It will also discuss any assumptions that are made in the
evaluation criterion, such as assuming that the resistance of wires in an
electrical circuit is negligible or that air resistance acting on a falling
object is zero.
Summary:
A hypothesis should contain the following elements:
- a brief summary of the basis for the proposal
- the proposal--generally an if-then statement--for
answering the research question
- a brief discussion of the variables involved in the
experiment (independent, dependant, controlled)
- a brief discussion of the assumptions made in the
evaluation
A hypothesis should not predict the experiments
outcome.

I think it will. |
A literature search has indicated that Bob's Cola is
acidic and that acid can dissolve tooth enamel. However, Bob's cola is only
in contact with teeth for a brief period when swallowed.
If soaking a tooth in Bob's cola for a prolonged
period of time does not cause a measurable loss of enamel then it's doubtful
that the brief contact during swallowing will cause significant damage to
enamel.
The dependent variable will be mass of the tooth and
the independent variable time immersed in Bob's Cola. The Cola will be
temperature controlled to normal body temperature. It is assumed that
bacteria in the mouth, saliva, or other food residues in the mouth would not
alter the results.
|
- Procedure
- The procedure should give enough detail so that a
knowledgeable person could duplicate the experiment but does not have to
include every minor detail. (Bullet statements are ok.) A procedure should
show a labeled drawing of the apparatus and discuss how lurking variables
are to be controlled.

Some Dos and Don'ts
Don't use first person singular or second person
pronouns (in other words "I" or "you") in the write up. This is
extremely bad form for technical writing.
Don't over generalize your conclusions beyond what
you have actually tested. Be specific.
Do use statistical tools such as regression
analysis, confidence intervals, and hypothesis tests in your write up.
Do include photographs of your apparatus and of
any observations you make.
Do include supporting data, computer code, and
additional analysis in a notebook on the table.
Do use a taller than normal backboard, but only if
you can fill it up.
Do include models, or pieces of equipment along
with your display.
Do put a descriptive title, date, labels on each
axis along with units on each graph.
Do use SI (metric) units.

- Data and Analysis
- Will generally present the data in both a table and
in graphical form. will include items such as pictures, statistical
analysis of the data, descriptions of computer programs, and sample
calculations.
|
- Conclusion
- The conclusion answers the research question by
applying the evaluation criterion to the hypothesis. The researcher should
summarize the basis for the conclusion, discuss possible
experimental errors, and discuss how the investigation could be improved
or continued in the future. A conclusion never introduces new data or
analysis. The conclusion should include potential applications.
Summary:
- answers research question
- summarizes supporting data
- discusses possible experimental errors
- includes possible improvements
- includes future work

The Backboard The middle panel should be 24" x 36" and the outside
ones 12" x 36" with information arranged approximately as shown. the title
should go on a panel attached above the tri-fold backboard. A good backboard
will include pictures, drawings, and graphs as well as text.
At Southside, the middle panel will be constructed in PowerPoint or Adobe
Illustrator and printed on the HP wide format printer, then laminated to the
back board using 3M spray adhesive. The document must be set up for the 24"
x 36" size with appropriate sized fonts from the beginning.
Likewise, the side panels will be with be printed on a 24" x 36", split
in half and laminated to the appropriate sides.
Remember that changes cannot be made after the board is printed. Be sure
to do the following beforehand:
- Run spell check
- Proof read everything--have a friend and your sponsoring
teacher also proof read.
- Use appropriate sized fonts
- Use light color gradients in the background. Generally pure
colors like green and blue are best. Gradients with with colors like beige
can make the backboard look aged or dirty. Never use solid colors for the
background.
