what makes ice melt faster?
Transcript of what makes ice melt faster?
Anna Katherine Jones
Independent variable: the independent variables are the salt and the sugar.
Dependent variable: the dependent variable is the ice because it stays the same in each trial.
Three cups of equal size, one labeled "control" ,one labeled "salt", and one labeled "sugar"
notebook and pen
fill each cup with water
add the same amount of ice to each (about 4 or 5 depending on the size of the cup
in the cup labeled "salt" sprinkle on a tablespoon of salt do not stir
immediately sprinkle a tablespoon of sugar into the cup labeled "sugar" do not stir.
start the stopwatch
note down the amount of time it took for the ice to melt completely into water for each cup.
clean out the cups and repeat the experiment three times or more. always keep careful notes .
analyze the data. figure out the average time it takes for ice to melt in plain water,water with salt and water with sugar
for further evaluation,try using different amounts of salt. feel free to experiment with other substances as well, like rubbing alcohol or sand
Trial 1 trial 2 trial 3 average
Control 50:43 45:18 58:27 51:29
Salt 58:51 36:21 1:10 54:94
Sugar 1:19 35:48 1:04 59.57
The purpose of this experiment is to determine what makes ice melt faster: Salt or Sugar?
I hypothesize that the salt will make the ice melt faster .
In conclusion, my hypothesis was incorrect. I discovered that regular tap water melts ice faster. We did have a few problems though in one of the trials the sugar melted faster than the rest. But all else worked out.
