5 Ideas for STEM-Related Halloween Fun at Home

It’s almost Halloween, a night that most kids love because they get to dress up as a spooky character and eat plenty of sweet treats. But aside from the parties, pumpkin carving, and apple bobbing, there are some fun STEM activities you can do with the kids to get them in the Halloween spirit.

Here are 5 brilliant ideas for Halloween STEM activities, courtesy of the lovely people at First Wonder Box.

Halloween STEM fun


Erupting pumpkin


What you’ll need:

A small pumpkin

Plenty of vinegar

Washing up liquid

Food colouring (optional)

Baking soda

Instructions:

Be warned, this activity is a little messy, so either do it outside or place the pumpkin in a large dish. Start by cutting the top off the pumpkin and hollowing it out. Fill the pumpkin to about half way with vinegar, then squirt some washing up liquid and food colouring in to the vinegar. Mix it all together, then add a heaped tablespoon of baking soda, give it a stir and marvel at the ‘explosion.’

How this relates to STEM

It’s science. The acid in the vinegar reacts with the alkaline baking soda and creates carbon dioxide bubbles which make the explosion.

 

Crafty Spider Webs


What you’ll need:

PVA Glue

Glitter (Any type or colour will do)

Plastic wallets

Instructions:

Use squeezy PVA glue to draw a spider’s web on a plastic wallet. Sprinkle the glitter over it, then allow it to dry. This can be a long process, so maybe do it then leave it overnight to dry and set. Peel the web away from the plastic wallet, turn it over, and leave it to dry for another few hours. Voila, you have some lovely glittery spiders webs to hang around your home.

 

Witches Brew


What you’ll need:

2L of white cleaning vinegar

A lot of baking soda

Food colouring of your choice

Plastic creepy crawlies and snakes

Instructions:

Pour 4 big cups of water into a big pot (or a witches cauldron!). Stir in 3-heaped tablespoons of baking soda, and then add a few drops of food colouring and some plastic creepy crawlies. It should look like a spooky witches potion! Mix everything together then add the vinegar, and your potion will start to bubble and fizz.

How it relates to STEM

Just like the erupting pumpkin, the acid in the vinegar reacts with the alkaline in the baking soda which creates carbon dioxide bubbles.

 

Googly Eye Slime


What you’ll need:

150ml of clear glue

1 tbsp. baking soda

Green glitter paint

3 tbsp. saline solution

Googly eyes (available from craft stores)

Instructions:

Squeeze the clear glue into a bowl then add 1 tbsp. of baking soda. Use the glitter paint to give it some colour, then stir in the saline solution. Mix everything together until the mixture is no longer sticky-this can take a little while. Add some fun googly eyes to make it look like real monster slime.

 

Dancing Ghosts


What you’ll need:

Coloured tissue paper

Tape

Blown up balloon

Instructions:

Cut some Halloween shapes out of the tissue paper. It can be anything from ghosts, to pumpkins and bats.

Tape the bottom of your shapes to a table. Rub the balloon over your jumper or hair to create some static then move the balloon over your shapes. The shapes will the start to ‘dance’ around.

How this relates to STEM

The balloon has extra electrons which makes it attracted to the tissue paper.

We hope you have inspired you to have some STEM-related Halloween fun!
