Conclusion
Wikians,
We have found a successful method to purify your salty water. Normally, you would use a pot and stove. But since you must quench the thirst of your whole population, you can do something different to purify large amounts of water. Follow these steps:
1.) Build a stainless steel pot with a circumference of 100 ft. and 60 ft. deep. Include a glass top to match.
2.) Build a glass bowl with a circumference of 90 ft. and 50 ft. deep.
3.) Build a large bonfire.
4.) Build two metal poles 50 feet away on both sides of the fire.
5.) Using thick rope, fasten the pot to the poles, so that it is hanging directly over the fire.
6.) Place the glass bowl in the pot.
7.) Pour the salt water around the glass bowl, so that it is only in the pot. Place the glass lid on top up-side-down.
8.) Let all the water collect into the glass bowl.
9.) Boil the water once again to be sure that there is no left over bacteria.
If you follow these steps, you will be left with a glass bowl of fresh water! Once you remove is from the pot, you can serve it to all in Wikians on your island. This method will make you lots of water at a time, so that you will always have plenty of fresh water for your people. This method insures 100% clean water, with absolutely no bacteria or salt leftover. By boiling the water once again, you are insuring perfectly healthy and bacteria-free water for all your people. We are glad that we could solve your salty problem and provide fresh water to drink for all the Wikians of Wiki Wiki Island.
Sincerely,
Bryahna. Emily, and Angela
The purpose of this experiment was to research and test which type of salt (iodized or un-iodized) would purify faster, and to research the best way to purify salt water for the Wikians of Wiki Wiki. Then Angela L., Bryahna T., and Emily H. would know if their hypothesis was correct, that the iodized salt would purify faster. When we first interpreted the outcome, Angela, Bryahna, and Emily predicted that iodized table salt would purify faster. We also predicted that the excess bacteria would be removed the second time that we boiled the water. After the experiment, we found that our hypothesis was true, iodized salt purifies faster than un-iodized sea salt. The data explains that our hypothesis was correct because in 6:00 minutes, the iodized salt had already produced 70ml of fresh water while the un-iodized salt had not even begun purifying. After 18 minutes, the un-iodized sea salt had completely purified, while the iodized salt took only 16 minutes to completely purify. When we tasted the water, there was absolutely no left over bacteria. Boiling the water a second time removed any left over bacteria in it. We learned how to purify salty water, and that a small difference in ingredients can affect the outcome of an experiment. Also, we learned how to compare two sets of data and make conclusions and comparisons based on the results. Some things that went wrong in this experiment were that the glass measuring cup was unstable from the boiling water, and the lid was difficult to lift because it was turned upside down. To prevent these problems in the future, we could use a sturdier glass cup. This would prevent it from shaking in the boiling water as much as it did. As far as the lid, we could hot glue a handle under it, so that we wouldn't have difficulties removing it from the pot. Some further research that we could do next time is use various different methods to purify the water. Then we could compare to see which method works faster. This data is connected to real life in many ways. We conducted an experiment using real salt water and real table salt that we normally use in our daily lives. These are normal ingredients that we see every day. Also, many people purify their own water using this same method. We should care about this in relation to our everyday lives because if we didn’t have fresh water, we would need to purify it in order to survive. Fresh water is something that every living species needs to live and function correctly. Also, we should care about this experiment in our daily lives because comparing two different things is something we do every day. Conducting this experiment went into depth on this subject, and helped us to understand how to compare two different items when put through the same procedures.
