My daughter loves experimenting with the classic Skittles experiment, so we thought we would adapt it to celebrate the festive season and the arrival of our own little scout elves. We have had fun designing Elf STEM Skittles experiment for kids, perfect for a little STEM exploration at home.
You don’t need much equipment to try this at home. Just a big bag of Skittles, a white plate, and a jug of cold water.
Elf STEM skittles activity for kids
First we bought a couple of bags of sweets to make sure we got the colours we needed – pink, purple, red and green.
My daughter designed a simple Elf shape featuring a face and colourful hat.
Then she poured a little water onto the plate. She made sure to pour the water slowly enough that the sweets didn’t move out of place, and made sure there was enough water to cover all the sweets.
Quite quickly the colours leeched out from the sweets.
The food colouring in the sweets is very strong and creates a pretty pattern.
So why does this happen? Well, the Skittles are covered in sugar and food colouring which dissolve as the water touches them. The coloured water then slowly moves around the plate.
The above process took a few minutes but we left the experiment out a little longer. Eventually all the colour came away from the sweets but the coloured water didn’t really change much more. My daughter was happy to eat the sweets after all this!
