__SCIENCE__ What water evaporates fastest (salt water, fresh water)

__Aim:__ My aim is to find out what evaporates the fastest, salt water or fresh water.

__Hypothesis:__ I think that fresh water will evaporate fastest because when I go to the beach I have never the sea water evaporate

__Equipment:__ 1. 2 pots 2. a stove 3. a bucket of salt water 4. a bucket of fresh water 5. a timer

__Method:__ 1. Get a bucket of fresh water and a bucket of salt water 2. Put the two different water’s in to two separate pots 3. Turn the stove on and turn two elements on, to the same heat e.g: 100 degrees for both elements 5. Put the pots on the two different stove elements 6. Turn the timer on and time them to see witch one evaporates fastest 7. Repeat this experiment 17 times

First Tables Results

First Results: Fresh water didn’t take as long as salt water so fresh water was the fastest with a time of 27:16 minutes and salt water evaporated with a time of 28:35 minutes.

Second Results: The second time I experimented fresh water evaporated faster, but they both took longer than the first time I experimented. Fresh water evaporated fastest with a time of 28:03minutes and salt water evaporated with a time of 31:47 minutes.

Third Results: When I experimented the third time they both evaporated with a time of 26:30 minutes.

Fourth Results: When I experimented on salt water and fresh water, salt water evaporated fastest with a time of 30:51 minutes (thats over half an hour, a long time) and fresh water with a time of 34:19 minutes.

Fifth Results: This time I timed them separately and salt water evaporated fastest again, salt water evaporated fastest with a time of 20:00 minutes which is the fastest time time for evaporating to cups (to me). fresh water didn’t evaporated as fast as salt water but still had a time of 23:56 minutes.

Sixth Results: When I experimented this time they both had the same time, they both had a time of 31:11 minutes.

Second Tables Results

First Results: When I did my first experiment with one cup, salt water evaporated the fastest with a time of 10:39 minutes and fresh water evaporated the slowest with a time of 13:12 minutes.

Second Results: When I evaporated salt water and fresh water at the same time with one cup the second time fresh water evaporated fastest with a time of 12:16 minutes and salt water evaporated the slowest with a time of 12:57 minutes

Third Results Fresh water evaporated the faster than salt water again with a time of 11:40 minutes and salt water with a time of 16:38 minutes

Fourth Results: When I experimented this time salt water evaporated faster than fresh water with a time of 12:34 minutes and fresh water evaporated slower with a time of 9:02 minutes.

Fifth Results: This time when I evaporated salt water and fresh water salt water evaporated faster than fresh water with a time of 11:00 minutes and fresh water evaporated slowest with a time of 14:48 minutes.

Sixth Results: When I experimented this time they where very close from each others evaporation times but fresh water evaporated faster than salt water with a time of 15:21 minutes and salt water evaporated slower with a time of 15:58 minutes.

Third Graph Results

First Results: When I experimented this time fresh water evaporated faster than salt water with a time of 44:23 minutes and salt water with a time of 45:00 minutes.

Second Results: When I evaporated fresh water and salt water salt water evaporated faster than fresh water did with a time of 40:31 minutes and fresh water with a time of 43:58 minutes.

Third Results: This time when I experimented fresh water evaporated faster than fresh water with a time of 45:06 minutes and salt water evaporated slower than salt water with a time of 46:27 minutes.

Fourth Results: When I evaporated fresh water and salt water this time fresh water evaporated faster than fresh water with a time of 45:42 minutes and salt water evaporated slower with a time of 48:47 minutes.

Fifth Results: Fresh water evaporated faster than salt water with a time of 43:15 minutes and salt water evaporated slowest with time of 45:29 minutes.

Conclusion:

My hypotheses was right fresh water evaporates faster than salt water. As you can see in my tables fresh water evaporated faster than salt water 9 times where salt water evaporated faster than fresh water 6 times also salt water and fresh water evaporated at the same time twice. Fresh water evaporates faster than salt water.
