How snowflakes form – level 1

How snowflakes form

23-02-2024 07:00

Snowflakes form when water meets tiny objects in clouds.

Snowflakes have different shapes. Their shape depends on temperature and on how much water is in the air. Snowflakes seem white. But they are clear. The light makes them look white. They have symmetry, too. It means that all parts look similar. They are pleasant to look at.

In 1611, Johannes Kepler wonders why snowflakes have six sides. He believes that this is because of good use of space. Scientists prove this hundreds of years later.

You can photograph snowflakes. But you need to be patient. It is not easy. It takes a lot of time to take a perfect picture of a snowflake.

Difficult words: tiny (very small), temperature (how warm or cold something is), prove (to show that something is true or it exists).

You can watch the original video in the Level 3 section.

What did Johannes Kepler believe was the reason for snowflakes' six-sided shape, and when was this theory proven by scientists?
