Hello my name is Jessica, my partners name is Suzy. We studied on Water Purification. Our science project was mainly on Distillation. We called our project Water Purification because we were mainly were talking and writing about how to clean dirty water so that it was clean enough to drink.
We decided to choose this topic because we were wondering how we can make dirty water into clean water. We also we wondering what method or machine we would have to use to make the dirty water clean, Distillation was our answer.
Our problem statement was that we were trying to find a way for poor people or for people that don't have clean water to get clean water by using a safe machine and a easy to use machine. Our hypothesis was that using distillation would work, but they would have to be careful because some liquids evaporate faster than water.
The method that we took was to first get as many books on Water Purification, Distillation, The Hydrologic Cycle and on Pollution. Secondly, we had to read and learn as much as we could on those topics. Thirdly, we had to decide on who would do what, like we had to split up our work (divide between us equally). In Addition, we had to write rough copies on our topics then type them on the computer. Lastly we had to glue our work on our backboards and now we had to do our projects.
The materials that we used for our project was a Distillation Apparatus. To make the water dirty we put pieces of bacon, soap, pieces of bread, pieces of pizza pretzels, dirty snow, some mud and water. We had to make sure that we didn't put a liquid in there that would evaporate before the water would.
Our results were that the first time that we did the distillation part it did not work so therefore we had to do about 4-5 times before it was 100% clean to drink.
Yes we do accept our hypothesis. If we ever had to use this method/project again we would have to distil the water than people would be able to drink it.
The easiest part of our science fair project was reading the books. The hardest part was the actual distilling part. There were no surprises but we did discover something and that was that we had to distil the waster about 4-5 times till it was actually clean. The funniest part was making the water dirty and making the distillation model.
I think that we did a marvellous job. We really tried hard and we had put a lot of effort into our project.
The most important thing that we learned was how you distil water, and how the hydrologic cycle works every single day. If we were ever stuck somewhere with no clean water we would know how to make the water clean.
