We’ve been very busy over the last few weeks testing lots of fun Christmas Science Experiments. You might spot some old favourites, but we’ve got lots of new ideas as well, including a collection of Elf STEM Challenges which have entertained us for hours!
We also have a science advent calendar to help you count down to Christmas.
Christmas Science in the kitchen
Learn about filtering with this gorgeous apple cider recipe.
We had lots of fun making these lovely mint flavoured chocolate leaves and learning about changes of state at the same time.
Try some hot chocolate science. Where will marshmallows melt the fastest?
This bowl made from peppermint sweets would be a great way to learn about changes of state, but do be careful with the hot candy.
Design and build a gingerbread house and test to see how strong it is.
How about some yummy peppermint creams, these would be great to give out to friends as a little gift.
Test different thicknesses of icing sugar and create marshmallow snowmen.
We also made a Christmas peppermint lolly, by growing sugar crystals. This is a bit messy and sticky, but if you can get it to work the end result is brilliant.
Christmas Science Experiments – Christmas Chemistry
How about setting up a fizzy elf lab ?
How about a making a fizzing Christmas tree or gingerbread men? We made ours using the same method as these fizzing rocks.
Our Grinch slime is sure to be a hit.
Try to dissolve a candy cane using different liquids.
In the playroom
Make some jumping snowmen or christmas trees using static electricity.
Can you make a Christmas themed magnet or marble maze?
We had a lot of fun with our Christmas themed shadow puppet.
Can you design a pulley to help the elves?
How about a Christmas themed cartesian diver?
These tinkering trees are adorable from Left Brain Craft Brain.
How about making some symmetrical Christmas trees?
This magnetic present trail was fun too, we put some paperclips inside a matchbox, then wrapped it up, before using the magnet wand to move the present around the board. A giant version of this would be great fun too.
Make a Christmas themed Optical Illusion – printable coming soon
Christmas Activities Outside
You could make some wonderful ice ornaments like Red Ted Art.
Make your own frost ( you can do this inside ) using the power of ice and salt.
Explore pine trees with this fun activity from Inspiration Laboratories.
Can you work out how tall your Christmas Tree is without measuring it?
Christmas STEM Challenges
Build and test some Christmas themed boats to investigate whether they sink or float?
Investigate to find the strongest paper chain materials.
We’ve also got a great collection of Santa STEM Challenges, including helping Santa find the North Star, catapult presents up a tree and fix broken toys.
For younger children
Practice fine motor skills by rescuing the elf’s jingle bells from the snow.
How about trying some sinking and floating with Christmas decorations?
If you like to get messy, how about some Christmas themed oobleck or even some candy cane flavoured oobleck.
How about making some sparkly ice? Be sure to let it melt a little before playing, remember very cold ice can be sticky.
How about a game of match the Christmas smell to the Christmas spice using play dough?
I love this snow dough from The Imagination Tree too.
Christmas Gifts and Cards
We love this walk through a holiday card from Babble Dabble Do.
You could make a teacher or family member a gift of lovely Christmas flowers.
Have you seen our Homemade LEGO Advent Calendar?
Or how about making a fun science kit as a gift for a curious child.
