Conducting Your Experiment and Collecting the Results
5. Conduct the experiment. Follow your procedure. Carefully record all observations and measurements. Take photographs and/or make sketches of important stages of the experiment. Are the results what you expected?
6. Repeat the experiment. Repeat each test at least three times. This helps to rule out that your results are not due to one-time chance. Are the results the same? You may realize that you need to redesign or adjust your experiment so that it gives reliable results. Unexpected conditions may become evident that you had not anticipated, but will need to control.
7. Analyze your results. Use charts, graphs and tables to make your results clear. This will help you to interpret what your experiment has revealed.
8. Draw a Conclusion. Based on your original hypothesis and the results of your experiment, what is the answer to the question? If the answer is not what you expected, why? Does your experiment suggest further experiments that could be done to investigate this question more thoroughly? Write out your conclusion in a clear and concise manner.
