How snowflakes form – level 2

How snowflakes form

23-02-2024 07:00

Snowflakes form when water vapor meets dust or pollen in the clouds. They all have different shapes due to different temperature and humidity.

In 1611, Johannes Kepler wondered why snowflakes had six sides. He thought that it was an efficient use of space. Scientists proved this theory centuries later. Although snowflakes appear white, they are clear. Their symmetry is pleasing to the human brain, much like other symmetrical objects in nature.  Snowflakes fall thanks to gravity and they follow universal laws of physics, just like objects in space.

Photographing snowflakes requires perfect conditions and a lot of patience.

Difficult words: vapor (mist or steam), humidity (how much water there is in the air), efficient (when something works perfectly without any waste), symmetry (when something is regular and its parts are in balance).

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

How do scientists explain the varying shapes and intricate patterns of snowflakes despite all forming in similar conditions?
