Fun science experiments for kids

These fun science experiments for kids are sure to keep boredom at bay. And the perfect indoor activity for kids when the wet weather hits. But just to be safe, keep a responsible adult on hand to make sure that all these experiments are done safely.

Colour changing milk

This is a great way to teach children about colour mixing. You just need milk, food colouring and a squirt of washing up liquid. Use a cotton bud to swirl the colours and then enjoy the magic as the colours mix together.

Elephant’s toothpaste

This super fun experiment does require an ingredient that you might not have in your cupboard. But it’s so easy to get, and your kids will be laughing about the results of this experiment for days to come! Warning: You might want to try this one outside.

Make your own play dough

Making your own play dough is one of the simplest science experiments out there. It’s all about chemical reactions! The ingredients come together create a mixture, where they’re physically combined but no reaction has happened. When the water and food colouring are added though, the mix forms a solution. Then the solution is heaped together and kneaded, which then forms a whole new substance because chemical reactions have taken place. How exciting!

Create your very own rainbow 

Not only does this rainbow jar make a great addition to your home, but it also teaches children about density as the heavier layers fall to the bottom, creating the rainbow effect.

A volcanic eruption

This classic experiment will have your kids erupt with excitement, whilst teaching them all about the fascinating world of volcanoes. Using common cupboard items like vinegar, baking soda and washing up liquid, this experiment couldn’t be simpler. Just be sure that children are supervised and standing a safe distance away when the action happens.

Bounce an egg

Pickle an egg in vinegar for several days and you’ll be left with a transparent bouncy egg. Don’t bounce it on your best carpet though, just in case it doesn’t work…

Grow your own crystals

This science project shows how crystals are formed, and the end results taste pretty good as well. While they’re easy to make, they do require a bit of patience – just keep reminding your kids that it will be worth it in the end!

Make water go for a walk

This impressive looking experiment is very easy to set up – you just need some jars, food colouring and kitchen roll. It helps explain capillary action – how water ‘climbs’ up to the top of plants and trees from their roots – in a totally visual way that most kids will get.

Make your own slime

The ultimate fun experiment, demonstrating what happens when different chemical compounds react together – and also providing plenty of enjoyment after it’s made.

All you need is PVA glue and some laundry detergent – Aldi’s Almat Laundry Gel is apparently the best one to use.

Play with dip-dye

Dip-dying fabric is a great way to learn all about molecules and bones, as the dye bonds with the cotton on your fabric and actually becomes – or “bonds with” – the material. It will also teach your little one exactly why getting permanent pen marks out of ANYTHING is so difficult.
