Mini Chemistry Lab Exploration Station

Sometimes I forget that my youngest child hasn’t necessarily taken part in basic 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 and she loved it.

Science for preschoolers

What you need

  • Baking soda ( Bicarbonate of Soda )
  • Food colouring
  • Jars
  • Water
  • Vinegar
  • Milk Oil
  • Water
  • Tray
  • Pipette
  • Vegetable oil
  • Beakers

We tried three super simple experiments, all in the tray so they didn’t make too much mess.

Baking Soda and Vinegar

  • 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.

This activity is a great first introduction to chemical reactions for older children, but for my 4 year old what was more important was watching her learn how to use a pipette and the correct way to pour a beaker, both things which I’d taken for granted.

Oil and water

  • Place a thin layer of vegetable oil in a flat container.
  • Mix up several small beakers of water and food colouring.
  • Use a pipette to drop tiny bits of the water and food colouring onto the oil.
  • Make a pretty picture.

In the interests 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

This is another great activity for little ones, see here for full instructions for colourful milk.

Fizzy rocks

Explore melting with some ice cream soup

Make a messy potion

Learn how to make giant bubbles

Make a volcano with snow, sand or even papier mache

How about making some fruity boats?

We loved this kool-aid oobleck.

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.
