Here is the template that was given in class:
I. First Paragraph:
Introduction
*What was investigated? Think about your Question.
"The problem that was investigated was...
does the reaction time of an alka-seltzer tablet dissolving, change with different temperatures?"
*Describe the problem. State the Purpose
"The purpose of this experiment is to determine if....
the alka-seltzer tablet would dissolve faster in 90 degree water, 70 degree water, or 40 degree water."
*Was the hypothesis supported by the data?
The results supported/failed to support the hypothesis.
The results supported the hypothesis.
*Compare your actual result to the expected result, State your hypothesis
The hypothesis stated that (If...then...because). The actual results were...
The hypothesis stated that "If the temperature of the water was increased, then the alka-seltzer tablet will dissolve at a faster rate, because the higher temperate will speed up the molecules, which will then speed up the reaction time. The actual results showed that the 90 degree water dissolved the alka-seltzer at 7.8 seconds, whereas the 70 degree and 40 degree water was higher than 15 seconds each.
*Include a valid conclusion that relates to the initial problem or hypothesis
The results were concluded because according to the research, (link to
research)...
molecules will react faster at higher temperatures such as 90 degrees.
*Did the findings support (or not) the hypothesis as the solution to the problem?
The results supported the hypothesis as the solution to the problem.
By looking at the research and data, the reaction time of the alka-seltzer tablet was affected
by the different temperatures.
*Do not worry about percentage error.
II. Middle Paragraphs: Discuss the major findings of the experiment
*How did your findings compare with other researchers?
If you are able to, see if you got similar results.
When looking at different experiments on alka-seltzer reaction time, the results were strikingly similar. Even though other experiments tested reaction temperatures and different reaction times were gathered, the conclusion still remained the same. The hotter temperatures caused the alka-seltzer tablet to dissolve at a faster rate.
*Each variable needs its own sentence.
Discuss your first independent variable and the results.
When the alka-seltzer tablet was placed in the 30 degree water, the dissolving process took 28 seconds for the tablet to completely dissolve. Once the tablet was placed in the water, bubbling and fizzing immediately started to happen for 28 seconds.
Discuss your second independent variable and the results.
In addition, when temperature was changed to 70 degrees, similar observations occurred but for a decreased amount of time. It took 17 seconds for the alka-seltzer tablet to dissolve and the water to stop fizzing and bubbling.
Discuss your third independent variable and the results.
In the last trial, the water temperature was changed to 90 degrees. In the 90 degree water, the alka-seltzer tablet dissolved the fastest, in 7.8 seconds. The bubbling stopped quickly and the water calmed down faster than the others.
Last Paragraph: Conclusion
What possible explanations can you offer for your findings?
*Why did you get these results.*
The results of this experiment were found because ________.
The results of this experiment were found because when the water's temperature was increased, the molecules moved more rapidly, the bubbling was at a quicker pace, and the alka-seltzer's reaction was sped up.
Evaluate your method
Were you able to control all your variables. How did you collect your data?
In this experiment, the controlled variables were the amount of water in the cup at the beginning of the trial, 50 mL. Even though the temperature of the water was changed, getting the same temperature throughout trial 1,2, and 3 proved to be
difficult. In every trial, the temperature was around the same degree, off by
one or two degrees each time, which may have skewed the data
slightly.
State any assumptions that were made which may affect the result.
How did you think your experiment was going to turn out. It was assumed in this experiment that ________.
What recommendations do you have for further study and for improving the experiment?
If this experiment was replicated, ______ would be done differently.
Comment on the limitations of the method chosen and any experimental errors that occurred during data collection.
Did you encounter any potential problems or did you have to make any procedural adjustments.
Suggest how the method chosen could be improved to obtain more accurate and reliable results
What are some possible applications of the experiment?
How can this experiment or the findings of this experiment be used in the real world for the benefit of society?
