Data Analysis and Conclusion (5-8)
Now is the time to organize, illustrate, and analyze your results. What does your data tell you?
Use your senses to make observations about your experiment. What is happening? Science Fair experiments should be repeatable. This means that you can do it more than once. In fact, you will need results from more than one trial to make sure that the data is as accurate as possible. You should have results that you can measure with your tools. Include your measurements (numbers and units) in your observations.
Make sure that your data charts are neat and organized and includes the conditions or materials that you are testing and the results of each test. You will need this information to create your graphs!
Don't forget to label the axes! The horizontal axis the the line that makes the bottom of your graph. The vertical axis is the line that makes the side of your graph. Usually, the horizontal axis tells what you are comparing (materials, actions, temperature, etc.) and the vertical axis give the numbers or numerical data. Include units (inches, degrees, seconds, etc.) for your measurements.
Make sure that your graphs are neat and easy to read!
Congratulations! You have completed your testing. Now it's time to tell what you learned. Did you prove your hypothesis? Believe it or not, a scientist's hypothesis is not always correct. That's why it is called an educated guess. After testing, scientists often have more questions and do more experiments. In your conclusion, tell whether your hypothesis was correct and what you learned along the way.
