Science Fair Projects
  • Part 2

Data/Log BookData refers to information gathered
during your investigation.
  • List all materials used
  • Notes on all preparations you made prior to
    starting your investigation
  • Information about the resources you use (books,
    people, libraries,etc)
  • Detailed day by day notes on the progress of your
    project
  • Any drawings that you feel might explain your
    work
  • Data that you gather from your investigation
    (notes, tables, charts, graphs)
  • Be sure that you date each entry in your log

GraphsThere are two main types of graphs.
BAR GRAPH
A BAR GRAPH IS USED TO DISPLAY DATA THAT DOES NOT
OCCUR IN A CONTINUOUS MANNER
LINE GRAPH
A LINE GRAPH IS USED TO DISPLAY DATA THAT OCCURS
IN A CONTINUOUS MANNER

MAKING A GRAPH
TITLE








Dependent variable Y (Vertical axis)
Independent Variable X (Horizontal Axis)
Title the title is a short description of the
data being displayed should include dependent
and independent variables Horizontal Axis (x)-
The Independent Variable (Manipulated Variable)
what you changed on purpose is displayed on the
horizontal axis Vertical Axis (y) The dependent
variable ( Responding Variable) what happened as
a result of what you changed is displayed on the
vertical axis
6
Graph/Spacing
  • Plan your graph so that your data will be evenly
    distributed across the horizontal and vertical
    axes.

7
Conclusions
  • Your conclusions should include
  • Statement of support or non-support of the
    original hypothesis
  • The results of this project ________ the original
    hypothesis.
  • Description of any problems or unusual events
    that occurred during your investigation.
  • What would you do differently next time.
  • Revised hypothesis (if data did not support your
    original hypothesis)

8
Writing a Conclusion
  • Before you write your conclusions, carefully
    examine all your data (graphs, charts, tables).
  • Ask yourself these questions
  • Did you get the results you expected to get? If
    not, how were the results different?
  • Were there any unexpected problems or occurrences
    that may have affected the results of your
    investigation?
  • Do you think you collected sufficient data? (Were
    there enough trials? Samples?)
  • Do I need to revise my original hypothesis? (If
    you write a revised hypothesis, DO NOT use it to
    replace your original hypothesis for this
    project!)

9
Conclusions
  • Questions Do all brands of paper towels absorb
    the same amount of water?
  • Hypothesis The cheaper the paper towel the less
    water it will absorb.
  • Conclusion The data collected does not support
    the original hypothesis. The cheapest paper
    towel (generic) did not absorb the least amount
    of water. The higher priced paper towel (Brawny)
    did not absorb the most. The revised hypothsis
    is the price of the paper towels does not affect
    the amount of water absorbed.
