Sometimes I forget that my youngest child hasn’t necessarily taken part in basic science experiments I did with the older children years ago, so when we had a bit of quiet time last week, I set up a simple science exploration station for her. We made fizzy baking soda and vinegar potions, experimented with oil and food colouring and watched colours fly through milk. These are all great science experiments for kindergarten age children and older curious kids as well.
She was mesmerised and spent a good hour mixing and experimenting with different combinations of the ingredients.
Science Experiments for Kindergarten
Messy Science Station
Things you need for a science station
- Baking soda ( Bicarbonate of Soda )
- Food colouring
- Milk Oil
- Vegetable oil
We tried three super simple science experiments suitable for preschoolers with the materials above.I set them all up in a tray so it wasn’t actually too messy.
Baking Soda and Vinegar Experiments
- Place a few drops of food colouring, water and a couple of teaspoons of baking soda into a few containers.
- Use the pipette to slowly add vinegar, stand back to watch the fizz.
This activity is a great first introduction to chemical reactions for older children, but for my 4 year old what was more important was how she learned to use a pipette and the correct way to pour a beaker, both things which I’d taken for granted she already knew!
Oil and water Experiments
- Place a thin layer of vegetable oil in a flat container.
- Mix up several containers of oil and food colouring.
- Use a pipette to drop tiny bits of the water and food colouring onto the oil.
- Make a pretty picture.
The oil and food colouring doesn’t mix with the water as oil and water don’t mix.
In the interest of an honest post, my 4 year old declared this was ‘boring’ and insisted on adding some baking soda so she could make a fizzy picture.
Colourful Milk Experiment
This is another brilliant science experiment for kindergarten, see here for full instructions for making colourful milk.

Fizzy rocks take a bit of preparation, but are totally worth it for the giggles when the rocks start to fizz and melt. You can even hide little bugs or toy figures inside.
Explore melting with some ice cream soup. Don’t forget to eat it afterwards.
Learn how to make giant bubbles. This is a brilliant activity for little ones, they can look for rainbows in the bubbles and create their own magic bubble solution.
Make a volcano with snow, sand or even papier mache. One of the best things about baking soda volcanos is that they can be erupted over and over again!
How about making some fruity boats? These are great for learning about sinking and floating. Children can make little sails, blow the boats with straws and even add toy figures to make the boats sink.
We loved this kool-aid oobleck as it smelled amazing. Oobleck can also be frozen!
All these activities use non toxic materials but please do supervise small children at all times. They wouldn’t be very nice to eat or drink.
