This project investigates the impact of salt on the melting rates of ice. By experimenting with varying amounts of salt, learn how salt lowers the freezing point of water and accelerates melting.
Increasing the amount of salt will decrease the time it takes for ice to melt.

Gather materials and set up your work area.
Fill each container with equal amounts of ice cubes.
Sprinkle a different amount of salt on each container (0g, 50g, 100g).
Start the timer as soon as you add salt.
Observe and record the time taken for the ice to melt completely.
Use the thermometer to measure the temperature of the water as it melts.
Repeat the experiment two more times for accuracy.
Analyze your data and calculate the average melting time for each salt concentration.
It is expected that the ice with more salt will melt faster than the ice with no salt. The data should support the hypothesis that salt accelerates melting.
