The objective of this experiment was to help the students learn about all the methods and tools that can be used in an experiment. The conclusions that were derived from the experiment for one had everything thing to do with what I know and for two had everything to do with what I learned. This experiment and the procedures given to do the experiment led me to learn more about how to accomplish accuracy with my measurements. Errors may have occurred with inaccurate measurements or accidents. The accuracy of transferring liquids could have easily been tampered with by splashing or missing. I believe that my accuracy is measuring the sugar could have been off, this could have made the results of that part of the experiment inconclusive. I have learned that accuracy and precision are very important when measuring. These methods can be used in everyday life such with cooking.
