Happy December! I’m confusing myself with all my Christmas science investigations, experiments and STEM Challenges so thought I’d pull them all together into one place to make it a bit easier.
Christmas Advent Calendar
This free downloadable science advent calendar has an activity for each of the 12 days in the run up to Christmas.
Christmas Science Experiments
These Christmas lava lamps will always be one of my favourite Christmas science experiments.
Create easy Christmas shadow puppets. Different sized snowmen would be good for this one, or a giant tree with decorations.
