Geometry (2D & 3D shapes): Megan's Snowflake
Challenge level ⭐⭐
(designed for children with prior knowledge of the Year 3 and Year 4 programme of study)
We are learning how to solve a natural world problem by using and applying our skills and knowledge of geometry (including symmetry and visualising).
Snowflakes begin their life high up in the earth’s atmosphere, where droplets of water freeze around dust particles to form tiny ice crystals. Temperatures need to be around – 35 °C for this to happen. As the ice crystals grow and fall to earth under their own weight, they clump together with other ice crystals to form beautiful snowflakes.
In this fascinating clip, we learn that no two identical snowflakes have ever been found. Despite this, we are told that all snowflakes have something rather unusual in common. What do you think this is? Watch the clip to find out.

Here is a photo of two snowflakes made out of paper. What is the same? What is different?
