Looking Back at Your Data Table
The data you collected during your
experiment in the data table is what
you are going to graph.
Two Types of Data Tables:
Which do you have?
IV
DV
Quantitative
Data
(Numbers)
IV
Qualitative
Data
(Descriptions)
DV
Graphing
Now, you need to decide which kind of graph
you will use:
• Bar graph- one snapshot in time
• Line graph- data collected over a period in
time
– If you collected Qualitative Data (descriptions)
then you will ONLY do a Bar Graph.
Ask your teacher before you make your graph to
ensure you are using the correct graph.
Filling in the Graph in Your Packet
•The three lines are for your titles.
oYou should have 1 main title at the top
oThen label your Y and X axis.
•The X axis should have your IV levels
•The Y axis should be the data from the DV
Graphing Online
Use the Website:

This can also be found on the Science Fair Webpage
on the Woodley Hills Website.

Always start with 0

Qualitative Graph
• Look back at your data table.
• You need to give you observations numbers. You can
do this by ranking them.
– Make sure these numbers match the
observations: if it was the most, then you should
give it the highest number.
Example:
Soil Types
Erosion
Ranking
Top Soil
A lot of erosion
3
Sand
Some erosion
2
Pebbles
Very little erosion

ranking

Parts of a Conclusion
Conclusion: This is the summary of your experiment
written as a paragraph. It should be at least 4
sentences long. Please include:
• The result of your experiment- “I conclude…”
• State if your hypothesis was supported by your data
or not
• What the experiment taught you- “I learned…”
• Write how you could improve your experiment
(there is always a way to improve it!)
Conclusion Example
Example:
I conclude that the white t-shirt was able to stay the coolest
temperature after being out in the sun on a hot and sunny day for 30
minutes compared to a black and purple t-shirts. The data I found
supported my hypothesis statement! I learned that when I am
outside on a hot and sunny summer day I should always wear white
or light colored t-shirts, so that I do not get too hot. I should not wear
dark colored t-shirts, because I will get much hotter. This is because
the white or light colors reflect the sunlight and do not absorb the
heat energy. The dark colors absorb the sun’s energy, which turns to
heat energy inside the t-shirt. If I were to do this experiment again, I
would have repeated my experiment more times to make sure that I
had the same results each time. That way I would be sure that my
data was correct.
Have you been thinking about your
presentation?
This year you have the choice to present
your science fair project on a display
board (like last year) or on a laptop
presentation!
What have you decided to do?
Next Steps…
• You need to get all your work typed!!
– If you have a computer at home, you can do this
at home.
– Your teacher will give you time to use computers
in schools.
