We went fishing for ice! The boys loved trying this experiment. They loved it so much we did it 3 times in a row. They were determined to catch more ice each time. By lowering the freezing point of water with salt you can catch some ice!
Cup or bowl
Here is video of the boys doing the activity!
First we collected all our materials. I told the boys we were going fishing for ice! They were excited to see what was going to happen.
First fill a cup or bowl half way with water. Then add some ice. The boys each added 5 pieces of ice to their cups.
Next I gave them each a piece of string. I told them to place the string on top of the ice cubes with one end of the string sticking out of the water. The trick is to get the string to touch as many of the ice cubes as possible.
Then comes the salt. You want to sprinkle each ice cube with a couple pinches of salt. If you use too much the string won’t stick.
Last wait about 30 seconds to a minute. Then lift the string and see how many pieces of ice you have caught! The boys loved this experiment so much that we did it a couple of times! They were determined to catch more ice each time.
