Can the Ocean Freeze?
In this experiment, we are going to investigate if the ocean can freeze
What you will need
- Marker
- Spoon
- Water
- Two large plastic bowls
- Salt
- Freezer
Instructions
- Use the marker to label the bowls “Bowl 1” and Bowl 2.”
- Pour four cups of water into each bowl.
- Add two tablespoons of salt slowly into Bowl 1. Stir until dissolved.
- Put both of the bowls in the freezer and leave overnight.
- Record your results the next day.
What is Happening?
Fresh water freezes at 0 degrees Celsius. When salt is added to water, it lowers the freezing point of the water by several degrees. The salt water can still freeze, but it will require a temperature lower than 0 degrees Celsius to do so.
