Create Ice With Different Freezing Points
Materials Required
* 3 cups of water * 3 different colored cups * Salt * Refrigerator to freeze
Method
  • Take 1 cup of water and add a pinch of salt in it, then add ½ teaspoon salt in the other cup and 1 teaspoon salt in the last cup of water. 
  • Mark the cups indicating amount of salt put in each cup and put all of them in the freezer to freeze.
  • Note the time taken by each of the water to become ice.
What is Learnt
The cup of water having a pinch of salt freezes first followed by the cup with teaspoon of salt and then the cup of water that has 1 teaspoon of salt. So freezing point decreases with the increase in amount of salt.
Conclusion
* The increase in proportion of salt brings down the freezing point of water. * Hence oceans and seas that contain more salt never freeze.
