Effects of water temperature

Hypothesis of this effects of water temperature science experiment

The same amount of water takes up more space when it is frozen.

Effects of water temperature science experiment procedure

• Fill an empty soup can with water. (Be careful of sharp can edges.)
• Set the can in a small bowl, and place it in the freezer section of a refrigerator. The bowl will catch any water that might spill from the can.
• Add more water if necessary so the water level in the can is at the very top.
• Leave the can of water in the freezer overnight.

In this science experiment, the quantity of water is being held CONSTANT, and the temperature is our VARIABLE.

• Take the can of ice out of the freezer in the morning.

The volume of water that fit into the can when it was a liquid is now too big for the can. The ice has risen above the top of the can because of the expanding water and its push against the bottom of the can.

Results & Conclusion of the effects of water temperature science experiment

Write down the results of your science experiment. Come to a conclusion as to whether or not your hypothesis was correct.

For bonus science fair experiment point

Now that you have experimented on water to find out what water does when frozen, you can conduct another similar science experiment to find out how much more volume the ice takes up than it did as a liquid by using displacement.

Hold the can tightly to melt the ice slightly around the edges of the can so the ice will come out as one block. Dip the block in a container of water and measure the water that it displaces.
