Incorporate a little learning into your summer with a fun science experiment that explores the properties of ice and salt. This project has a simple supply list, requires no prep, and has little clean up. The perfect project for an active family!
What you need:
What you need:
- Water
- Ice
- Salt
- String or yarn
What to do:
- Fill a glass or container with water.
- Put ice in the water.
- Cut a piece of string or yarn.
- Try to drop the string into the water and get the ice to stick to the string (it won't work).
- Sprinkle a generous amount of salt on the ice.
- Place the string on top of the ice with one end of the string hanging off the edge of the container and wait a minute.
- Now lift up on the end of the string and watch the ice come up stuck to it!
What's happening:
Adding salt lowers the freezing point of water and melts the top layer of the ice. As the water cools, it refreezes around the string, bonding the ice to it.
Your kids will love seeing how many cubes they can get to stick to their string. You'll love that they are getting a little summer time science lesson at the same time!
