Christmas Science Experiments

My new favourite Christmas resource is this print and play pack of paper based festive activities! Race Christmas liquids, make spinning sleighs and more.

These Christmas lava lamps will always be one of my favourite Christmas science experiments. They can be used over and over again and make a lovely unusual Christmas decoration.
