Great Ice Cube Race
These science experiments test the rate different shapes of ice cubes
melt. Each ice cube contains the same amount of water. In this
experiment you will use ice cubes that have different shapes and see if
the time it takes them to melt varies with the shape of the ice cube.
Testing melting ice cubes
- Several different shaped ice cube trays
- Measuring spoons
- Food coloring
- Wash and clean all your ice cube trays.
- Mix a few drops of food coloring into a bowl of water.
- You must fill all of the ice cube trays individual containers with the same amount of water for this experiment.
- To do this make sure that each section in the ice cube tray will hold 2 tablespoons of water.
one of the ice cube trays hold less than 2 tablespoons add smaller
amounts of water to the container to determine how much it will hold.
- Fill all the compartments in all of your ice cube trays with exactly the same amount of water using your measuring spoons.
- Place the ice cube trays on a shelf in the freezing compartment of your refrigerator overnight.
- Do not stack the ice cube trays on a shelf for this experiment because it might effect how they freeze.
- The next morning place individual ice cubes on different plates.
- Time the rate of melting for an ice cube from each type of tray.
- Record your results.
- Repeat the experiment with the rest of the ice cube timing the melting time for each ice cube.
- Record these results also.
- Find the average time it took for each different tray of ice cubes to see if the melting times were different.
Sinking the Titanic
Great icebergs break off from glaciers near the North Pole and South
Pole. The Titanic, billed as unsinkable, hit an iceberg in the North
Atlantic on April 14, 1912 and sank. The iceberg had been floating
around the ocean and was not spotted until 4 minutes before it collided
with the ship. The iceberg survived for a while but the Titanic did not.
