Suggested Teaching Instructions
Document Description
The frozen Hector Falls near Watkins Glen, New York, circa 1900.
Historical Context
For a waterfall to freeze, the temperature has to be very cold. Water is made of tiny, moving particles called molecules. When water gets cold, the molecules slow down and stick together, forming ice. Because water flows very quickly at a waterfall, the water molecules are usually moving too fast to get stuck together, even if they are cold. However, if the temperature gets cold enough, water molecules at a waterfall will slow down enough to form ice. After the first ice crystals form, the rest of the waterfall freezes more easily.
