Why Does Ice Float in Water?

 

Yes, even though ice is a solid, it floats in water. Ever wonder how ice floats in water?

 

Water is made up of small particles called molecules. In water the molecules are close together. But in ice, the molecules have bigger gaps between them which make them more spread out. Even though the molecules in ice take up more space, the ice is lighter than water. This is what makes it possible for ice to float on water.

 

Try This at Home!

 

Put ice in a glass of water. When the ice melts, will the water overflow the glass? If you try this, then it wont. The numbers of molecules stay the same. The number of molecules stay the same weather its ice or water!
