ICE CRYSTALS
A snowflake is formed when ice crystals have gathered in a cloud.
It starts with a germ that the water molecules hit. And so ice crystals are formed.
On page 11 are six models showing the formation of an ice crystal. Write a short text to each picture explaining what can be seen.

What can be the germ for an ice crystal?
Of what do water molecules consist?
A warm cloud contains more water molecules than a cold cloud. Therefore ice crystals are formed faster and with more details in warm clouds.
Ice crystal with few details.
Ice crystal with many details.
What does the model on page 12 show?
What happens when the aggregation of ice crystals gets heavy?
What is the basic structure of an ice crystal?
The light emitted from the sun is called “white”. It contains all the colours that humans can see.
When the ice crystals in the snow reflect the sunlight, this is perceived as white.
