December is fast approaching and I’m getting confused with all my science research, experiments and Christmas STEM challenges, so I thought I’d put it all together in one place to make it a little easier.
Here you have the ULTIMATE List of Christmas Science Experiments for Kids!
The ULTIMATE List of Christmas Science Experiments for Kids
Christmas science experiments
Print and reproduce science experiments on paper.
My new favorite Christmas resource is this one. print and play package of festive activities on paper! Race with Christmas liquids, make spinning sleighs, open magical hollies and more. The idea behind this booklet is that you print the packet, complete the activities and then recycle everything, so there is almost no waste!
Christmas Science Advent Calendar
This free downloadable science advent calendar It has an activity for each of the 12 days leading up to Christmas. Simply click on each ornament to access that day’s activity!
Flying Santa STEM Challenge
Use my handy template to set up a Santa STEM Flying Challenge. They work the same way as a straw rocket, but with a flying Santa Claus instead of a rocket!
Festive lava lamps
My Christmas Lava Lamps It will always be one of my favorite holiday science experiments. They can be used over and over again and make a beautiful and unusual Christmas decoration.
Christmas shadow puppets
Christmas shadow puppets They are very easy to make and very fun even for very young children. Snowmen of different sizes or a giant tree with decorations would be good for this one.
Frosty the snowman
Do Frost appears on the outside of a can. using the freezing power of ice and salt. This activity is fun for younger children as it is visually appealing and a good investigation for older children to discover what happens to ice when it is mixed with salt.
Festive optical illusion
Optical illusions are fun any time of year, but this holiday version is my favorite. Use it to put decorations on a treea snowman’s face or anything else you can think of. The FREE download includes a template to make the activity even easier.

Super strong candy canes
Hang Christmas decorations on candy canes. to know how strong they are. Just don’t use decorations that could break if dropped.
dissolve candy canes in different liquids. Vinegar and hot and cold water are good liquids to try first. For an edible experiment, place a candy cane in a warm, hot chocolate drink.
Filtered apple cider.
Do lovely apple cider to learn about filtering. This is a really fun Christmas cooking activity, and the apple cider tastes and smells amazing!
melting marshmallows
Discover How long does it take for a marshmallow to melt? in your hot chocolate. One idea for this activity is to find out if many small marshmallows melt faster than one or two large ones.
