Why does ice float in water? - George Zaidan and Charles Morton
Let’s Begin…
Water is a special substance for several reasons, and you may have noticed an important one right in your cold drink: ice. Solid ice floats in liquid water, which isn't true for most substances. But why? George Zaidan and Charles Morton explain the science behind how how hydrogen bonds keep the ice in your glass (and the polar ice caps) afloat.

For a look at the mathematics of sea ice, check out this video from the the U.S. National Science Foundation, that explores just how porous sea ice can be.
To study ice, as well as environmental conditions, scientists (and mathematicians) often use Ice Cores. You can simulate your own ice core study in the classroom with this lesson plan from the Byrd Polar and Climate Research Center.
And for just about everything else you need to know about just about every type of ice, the Canadian government has this comprehensive database that covers everything from Sea Ice cycles to Ice Shelf mechanisms.
