Conclusion

I conducted an experiment to find if sugar and salt affected the freezing point of water. I formed a hypothesis based on research that I had done about water’s freezing point and the characteristics of salt and sugar. My hypothesis was that by adding sugar or salt to water that the freezing point of water would become lower. I proved my hypothesis to be true. After following careful procedures and observing what happened, I came to a conclusion. Based on the data that I had collected from the experiment, the freezing point in both the sugar water and the salt water were a great deal lower than waters original freezing point of zero degrees Celsius. Even though I proved my hypothesis to be true there are a few things I would do differently if I was to repeat the experiment. I would use longer thermometers so I could read the temperature with more ease.   I also believe having a longer thermometer would allow me to have more accurate readings because there are more lines or a larger range. The second thing I would do differently is that I would use clear test tubes instead of colored test tubes. The colored test tubes made it harder for me to see the ice crystals forming. With the clear test tubes, I could see the exact moment the ice crystals begin to form and therefore can record the most precise temperature. Other than those to minor flaws the experiment went very well. I was pleased to see that the research I did lead me to a hypothesis that was backed up by a valid experiment.
