Transcript of What Makes Ice Melt Fastest?

By Betty Nguyen My
Hypothesis Procedure Materials Data Salt can melt ice melt fastest because
the average of salt was 48 minutes and 44 seconds. This science fair project came out as i planned because in my research it said that salt would make it melt faster. Cause When things freeze, or become solid from a liquid state, the usually form a crystal structure at the like snowflakes. If you add salt to water
then it will make it harder for it to
to a crystal. Sugar Sand
trial 1= 1hr 4min 15sec trial 1= 50min 17s
trial 2= 58min 22sec trial 2=48min 52s
trial 3= 1hr 15min 9 sec trial 3=52min 9s
average= 1hr 6min 22sec average=50min 26s
Pepper
trial 1= 1hr 28min 1sec
trial 2= 1hr 32min 19sec
trial 3= 1hr 25min 11sec
average= 1hr 28min 44sec
Salt
trial 1= 49min 11sec
trial 2= 49min 6sec
trial 3= 47min 15sec
average= 48min 44sec
Conclusion What Makes Ice Melt Fastest? If I put salt on ice then it
will melt faster. First you would need to gather your materials
Then put two ice cubes on each plate and do that for three plates
Then you would put 1 teaspoon of Sugar on the plates each
And you would time each on until they melt
Then do the same for Pepper, Salt, &
Sand
Make sure you have three trials
for each 3 teaspoons/each
3 stopwatches/each
2 ice cubes/each
3 small plates/each
Sand
Salt
Pepper
Sugar
Research Pure water freezes at 0 degrees Celsius or -32 Farenheit. When things freeze, or become solid from a liquid state, the usually form a crystal structure like snowflakes. if you add stuff to water, like salt, it makes it harder for water to form a crystal structure.So when salt is added to wet snow, the part that isn't frozen yet will have a harder time freezing. Also when we have
ice on the road the city bring out people with trucks and they pour salt to make ice melt faster for the people to drive. Bibliography Olson, Andrew. Science Buddies.
