TED-Ed: Why does ice float in water? - George Zaidan and Charles Morton
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...

Polar & Non-Polar Molecules: Crash Course Chemistry
Molecules come in infinite varieties, so in order to help the complicated chemical world make a little more sense, we classify and categorize them. One of the most important of those classifications is whether a molecule is polar or...
