Pictures of four places move one at a time onto a chart of temperature (cold to hot) and precipitation (little to lots): the tundra is cold with little rain or snow, and in warmer places very little rain makes a desert, more rain a grassland and lots of rain a forest. A panel beside the chart then adds the water biomes, grouped by salt into fresh water (lakes and rivers) and salt water (oceans), and the video ends on a one-line recap.

Transcript
What the lesson says
What is a biome?
A biome is a large region where the climate and the living things are alike.
Land biomes are grouped by temperature, from cold to hot.
They are also grouped by precipitation, like rain and snow.
The tundra is very cold, with little rain or snow.
A desert gets very little rain.
Both are dry, but the tundra is much colder.
A grassland gets more rain, enough for lots of grass.
A forest gets lots of rain, enough for many trees.
Tundra, desert, grassland and forest are land biomes.
Water biomes are grouped by how salty the water is.
Lakes and rivers are fresh water biomes.
Oceans are salt water biomes.
Land biomes are grouped by temperature and precipitation, and water biomes by salt.
