What you’ll learn

When Water Turns to IceUnderstand that water freezes into solid ice when it gets cold enough (0 °C / 32 °F).When water gets very cold, it freezes and becomes ice at zero degrees Celsius (thirty-two Fahrenheit). Ice is hard, cold, and slippery. Frost is a delicate kind of ice that grows on cold windows.
The Magic of SnowflakesLearn that snow is made of tiny ice crystals from clouds, and every snowflake has six sides.Snow is made of tiny ice crystals called snowflakes that form in cold clouds and float down. Every snowflake has six sides or points, and no two are exactly alike. Fresh snow feels soft and fluffy because it is full of air.
Big Ice, Little IceExplore different kinds of ice, including icicles, glaciers, and icebergs, and compare ice with snow.Ice comes in many shapes and sizes. Icicles are pointy spikes of frozen dripping water, glaciers are giant slow rivers of ice on land, and icebergs are big chunks of ice floating in the sea. Ice is hard and slippery, while snow is soft and fluffy.

Questions this course answers

What happens to water when it gets very, very cold?

When water gets cold enough, at zero degrees Celsius (thirty-two Fahrenheit), it freezes into hard, solid ice.

How does ice feel when you touch it?

Ice is frozen solid, so it feels hard and cold, and its smooth surface is very slippery.

Where do snowflakes come from?

Snowflakes are tiny ice crystals that form high up in cold clouds and then drift down as snow.

How many sides does every snowflake have?

Ice crystals always grow with six sides, so every snowflake has six points, and no two are exactly alike.

What is a glacier?

A glacier is a giant, heavy sheet of ice on land that creeps along slowly, like a slow river of ice.

Which one is soft and fluffy?

Fresh snow is full of tiny flakes and air, so it feels soft and fluffy, while ice is hard and solid.
