Christmas Science - Snowflake Crystals KS1

Christmas science for KS1: grow real crystals, test which material keeps hot chocolate warm, design symmetrical snowflakes and sort evergreen trees.

The real science behind the season, with two experiments using household items and facts that make children stop and say “wait, really?”

What children will explore

• Reindeer - Arctic animals with ultraviolet vision and antlers that grow fast
• Snowflakes - hexagonal ice crystals that always have six arms
• Christmas trees - why needles stay green: a waxy coating, a small surface area and antifreeze sap
• The robin - puffs up its feathers to trap warm air like a duvet
• Stars and the winter sky - clear winter nights and how to find Orion’s belt
• Gingerbread - kitchen chemistry: bicarbonate of soda and an acid make bubbles, and heat turns the dough golden brown
