Why does ice float?

• water expands when it freezes, making ice less dense than water

• water compacts when it freezes, making ice more dense than water

• hydrogen bonds in water push the ice to the surface

• ice is afraid of water, and avoids it

Water is a universal solvent because it...

• It can be found anywhere
