I’ve found my 5 year old to be incredibly curious at the moment, always asking questions and wanting to know how things work. Even something as simple as a rain gauge has been VERY exciting for her. With that in mind I’ve pulled together a list of great science experiments for kids of all ages! The age ranges mentioned in this post are just a guide, most science is fun for all ages if you tweak the activity a little bit.
I’ve also got a couple of science books available if you fancy taking a look.
Science Experiments for 4-6 Year Olds
Bubble snakes are very easy to make. Try blowing harder and then more slowly and look for rainbows in the bubbles.
Practice drawing or writing with fizzy paint.
Try some ice painting. This always keeps my children busy for ages. Another idea is to freeze a 3D shape and paint that. Cake moulds work really well for this.
Make some filter paper butterflies. This is a fun creative, chromatography experiment.
These superhero themed cress heads are super cute and perfect for learning about germinations.
Find out how many of your own feet tall you are. Is there a pattern?
Children can learn abour what’s inside their body by drawing around themselves or a friend on a roll of paper and then adding in a skeleton or even organs.
A pine cone weather station is a fun way to learn about the weather. Thanks to Rainy Day Mum for this one.
Explore numbers with a Numeracy at Home box.
Learn about static electricity with these jumping frogs.
Trick your eyes with this super easy optical illusion.
Try to make different shaped bubbles, does it work?
Learn about waterproof materials with this fun activity using soft toys or try my Save the Dinosaur waterproofing activity.
Make a magnet maze and learn about magnetism. Can you make a huge version?
Explore freezing and melting with slushy drinks, you could even try some colour mixing.
Make some coloured ice cubes for more fizzy fun or how about some coloured rocks?
Find out about arm span and its relation to height in this easy activity.
Make some shadow puppets or a shadow frame and then put on a show. What happens to the shadow when you move it away from the light source?
Make mixture with toys. This is great for starting to lean about properties of materials.
Try some colour mixing with jelly.
Sort Ariel’s treasures into groups depending on their properties.
Start to learn about what conditions green plants need to grow with this cress caterpillar.
Have some messy fun with oobleck!
Make some simple patterns using DUPLO.
How about setting up a chemistry lab in the kitchen? all you need is some coloured water, oil and pipettes.
Science Experiments for 7-11 Year olds
Try a bit of science magic? Can you make an egg bounce?
Learn about oil and water not mixing and density with this density jar. Experiment with different objects floating on the layers to make it more fun. What happens when you shake it?
How about making some simple ‘shooters‘ like Red Ted Art, what happens to them when it’s windy? Do they move further if you blow harder?
We LOVE these candy science experiments!
Learn how to clean dirty water using filters or design and build a toy filter.
If there’s a Science Fair coming up, we’ve got lots of easy and impressive science fair projects to try too!
Find out what makes the best sandcastle? Is dry or wet sand better?
More great science experiments for kids
Adult help is definitely needed for this one, but a Water Powered Bottle Rocket is always a big hit in our house.
Make honeycomb, pancakes, meringue and more in this collection of tasty kitchen science experiments and activities.
If it’s coming up to Valentine’s Day we’ve got lots of easy Valentine science experiments and activities too.

Wow wow wow!
So much to try …. good job it is half term!!
So many fabulous ideas, I think Syd would enjoy some of these at 2 and a half- and my older boy too- if this rain carries on we will be back for a look during half term next week!
This is a great list of activities for half term! We had traffic light jelly last night and the kids wanted to know how I got the colours to stick. I love their curiosity at this age.
These are FANTASTIC and super fun activities!! Thank you.
Bookmarking this for next week as I fear with this bad weather we might be house bound most of half term!
Ohh nice Emma, I think my girls would enjoy these and they are nearly 7! Mich x
So glad to come across this!! These activities will be a great addition to our family parties and get together this year! Thank you!
