1. The ice trays were filled with the same volume of water
4. 1 ice sample from each ice tray was taken out simultaneously
5. The time taken for the ice samples to melt was recorded
6. Steps 3-5 were repeated 4 times. The average melting time of each respective shape was recorded.
7. Rate of melting was calculated using the formula:
8. A graph was plotted to compare the rate of melting
2. The ice trays were placed in the freezer

Flower
Sphere
Cube
Rectangle

The sphere-shaped ice melts the slowest
3. The ice trays were taken out from the freezer simultaneously
Introduction
Objectives
-Uses of ice
-Chilling of beverages
-Causes dilution
-To find out which shape of ice melts the slowest

Factors that affect
rate of melting
- Temperature
- Surface area

The ice with the smallest surface area will melt the slowest.
Sources of error
-Measuring spoon not precise
-Only 10ml of water was used
-Difficult to see if the ice have completely melted

Time(s)
surface area(cm^2)/average time taken(s)
