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

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.
