Melting Ice With Salt

Sarah Atkinson

Any Questions?

Purpose

To discover which type of salt will melt ice quicker

Materials & Amounts

  • (16) 10 oz cups
  • Measuring Cups (1/2 cup)
  • Measuring Spoons(1 Tbsp)
  • Water
  • Freezer
  • Kosher Salt
  • Sea Salt
  • Ice Melt
  • Iodized Salt
  • Timer
  • Measuring Cup (mL)

I think it turned out this way because Sea Salt had the most sodium. In Trial 3, the amount of water that came out was lower than the other trials. I think it is lower because that trial may have gotten mistimed.

Hypothesis

If I put 2 tablespoons of Sea Salt on a 1/2 cup of solid ice it will melt more than any other type of salt within 45 minutes.

In my project I put 2 tbsp. of salt on a 1/2 cup of frozen water and timed it for 45 minutes and then measured the amount of melted water that came from the ice, and then recorded my data.

What type of salt do YOU think will melt ice quicker?

Procedures

Real Life Application

This can be applied to your life because you now know that Sea Salt melts ice quicker than the other 3 types of salt I tested. So, when it snows y

a. Sea Salt

b. Ice Melt

c. Kosher Salt

d. Iodized Salt

1.Fill a 10 oz clear plastic cups with 1/2 cup of water(4x)

2.Freeze cups of water until frozen solid

3.Measure 2 tbsp. of each type of salt out

4.Pour each type of salt on top of individual cup of ice.

5.Leave for 45 minutes

6.Pour the melted liquid and measure the amount of water that comes out

7.Record Data

Data

Variables

  • Independent: Type of Salt

Conclusion

My hypothesis was correct because Sea Salt did melt the most ice.

Constants

c

average

Data

So, with the data above, which type of Salt melts ice quicker?

Variables

  • Dependent: Amount of Ice that was melted

I did not research anything, I got the idea from a family member and continued my experiment from there on my own.

If I did this experiment again, I might add more than 2 tbsp. for each 1/2 cup frozen water because I would get more water at the end of the 45 mins.
