2. Question & Hypothesis
Question: Does the shape of an ice cube affect how quickly it melt.
Hypothesis: The shape of an object will affect how quickly it melts

3. Research Water is the only liquid that expands when it freezes
Water freezes at 0 degrees Celsius
The surface area of an ice cube affects how fast it melts

4. Materials and Procedure
Materials: Metric measuring cup, sphere form, cube form and disk form, thermometer, metric ruler, freezer, wire rack, digital watch and camera.
Procedure
Fill each form with 100ml of water
Freeze overnight
Place frozen shapes on drying rack and measure the thickness of each
Measure the thickness of each shape every 15 minutes
Measure the temperature of the room and the ice cubes
Note which shape melts the fastest

5. Experiment

6. Data Sheet Percentages:
Measure the percentage each cube melts every 15 minutes
Time 0:00 - Cube, 0.00%, Sphere, 0.00%, Disk, 0.00%.
Time 0:15 - Cube, 0.00%, Sphere, 3.85%, Disk, 4.44%
Time 0:30 - Cube, 16.67%, Sphere, 13.46%, Disk, 61.11%
Time 0:45 - Cube, 20.00%, Sphere, 21.15%, Disk, 66.67
Time 1:00 - Cube, 26.67%, Sphere, 23.08%, Disk, 77.78%
Time 1:15 – Cube, 33.33%, Sphere, 26.92%, Disk, 100%

8. Conclusion
My hypothesis was that the shape of an ice cube affects how quickly it will melt. In my experiment I found out that a thin disk melts faster than a cube or a sphere. My hypothesis was correct.
