How does the temperature of water affect the time it takes to freeze into ice cubes? By Jeremy Chong

Hypothesis I predict the water with the lowest starting temperature will freeze first because it will need to cool down the least.

Materials Distilled Water Measuring Cup Stopwatch Thermometer Freezer 8 plastic cups Microwave

constants Water Cups Thermometer Freezer Stopwatch

Procedure Pour 500 milliliters in each of the plastic cups #1-4 . Heat the cups #1-4 in the microwave until the water temperature is 90 degrees Celsius. Once desired temperature is met, place cups #1-4 in the freezer and begin timing with the stopwatch. Check the cups every 5 minutes to see if the water has completely frozen. Once all of the water is frozen, record the time.

Procedure continued Pour 500 milliliters in each of the plastic cups #5-8 . Heat the cups #5-8 in the microwave until the water temperature is 20 degrees Celsius. Once desired temperature is met, place cups #5-8 in the freezer and begin timing with the stopwatch. Check the cups every 5 minutes to see if the water has completely frozen. Once all of the water is frozen, record the time.

Data to be collected The data collected would be the time it took for each cup to freeze. The time for each cup would be displayed in a bar graph.
