Advanced Science Process Skills
Conclusion
A conclusion is a reexamination of your original
hypothesis in regards to the data you have
collected.
Conclusion
Your conclusion will continue by describing how
your result prove or disaprove your hypothesis.
Conclusion
Your conclusion includes what questions you have
developed in doing the experiment. It is also
includes how you might chang your ecpeiment.
Conclusion
If you were to continue this topic in order to
explore those questions that you developed
during the experiment.
Example
Use the experiment and the data table to find the
following information and then write a conclusion of
the findings.
Example
A person wants to know if different pH levels will affect
the growth of the plant. They come up with the following
experiment. Ten pots of plants with different soil pH
levels while other plants are grown in soil with no pH
change. The chosen plant to grow is the snap bean. Each
plant is given the same amount of sun, water, and grown
in the same pot size. The plants are measured after
three weeks of growth and the following data is
obtained.

in the same pot size. The plants are measured after
three weeks of growth and the following data is
obtained.
Finding the Answer
• A. Hypothesis: If the amount of pH in the soil is
increased then the growth of the plant should decrease
because plants like to grow at a neutral pH level.
• B. Independent variable: pH levels of the soil
• C. Dependent variable: growth rate
• D. Controlled Variable(s): same amount of sun, water,
and pot size
• E. Experimental group: same amount of sun, water, and
pot size
• F. Control Group: plants in regular soil
Parts of Conclusion
Must be written in a paragraph form. The conclusion
should include:
1. Explain what your data means. Discuss any trends
seen.
2. Does the data support your hypothesis? Is your
hypothesis correct or incorrect?
3. Did you collect enough data? Should there have been
more subjects in the experiment?
Parts of Conclusion
4. Did anything happen during the experiments that may
have affected the results?
5. If you could do this experiment over again what would
you do differently next time?
6. What other experiments could you do to further test
this?
Conclusion
In this experiment, the pH levels of different soil levels were tested.
It is believed that a neutral pH would be the level at which the plant
grew the most. The data shows that as pH level increases so does the
growth until a pH level of above 7.0 is reached, then the growth rate
declines. At the pH level of 6.6 and 6.8 the amount of growth after
three weeks was the exact same. This data does not support the
hypothesis because these plants like to grow in a slightly acidic soil.
If the number of plants tested were increased and the amount of
time measuring growth was increased, then perhaps a different trend
would be shown. Another experiment that could be done on the plants
could be if the levels of nitrogen in the soil is increased then the
amount of growth should also increase.
