Ice Fishing Science Experiment is a classic science experiment perfect for kids who are learning about ice and temperature. This quick science project takes just a few minutes to do, and kids are fascinated by their “magic” results! It’s perfect for states of matter science lessons for young kids too.
Getting the Ice Fishing Science Experiment Ready
Setting this experiment up is super easy, and it takes very little advanced prep. You will need:
You won’t have to spend any time in advance prepping for this activity, other than printing the worksheet. You should also make sure the cans or whatever container you use for this activity won’t cut the children’s hands.
Doing the Ice Fishing Science Experiment
Fill each can with water. Place about 6 ice cubes in each cup.
Let the kids place their string over the ice cubes. Do they catch anything?
Show the kids how to place the string over an ice cube, then sprinkle a small layer of salt over the string. Wait about 30 seconds, then try to pick up the string again.
The ice cube should cling to the string.
A few things can go wrong with this activity. If you use too much salt, the ice will melt too fast and the string won’t stick. If you wait too long, the string will fall off again. If you don’t wait long enough for the ice to form, the ice cube will fall off quickly as you pick it up. Experiment to see what works best in your class!
The Science Behind the Ice Fishing Science Experiment
Fishing for ice shows kids how salt can affect the properties and temperature of ice. When salt is added to ice, it lowers the melting point of the ice. But when the ice is surrounded by freezing temperatures, it quickly freezes again, causing ice to form again over the string. When this happens, the string can “magically” pick up the ice!
