A Rainbow in a Jar 🌈

This morning in the Discovery room the children wanted to do a science experiment exploring liquid. The name of the experiment was Rainbow 🌈 in a jar and the learning intention for the children was to be introduced to the concept of density of liquids.

4 liquids were used which were all of different densities.  They included golden syrup, fairy liquid, oil and water. The children then had a discussion as to which liquid had the ‘thickest density’. They correctly named the golden syrup to be the first liquid in the jar.

The golden syrup was then poured into the jar followed by the fairy liquid, water and oil. A rainbow effect was then created in the jar. The children enjoyed naming the colours of the liquids and especially watching each coloured liquid sit on top of each other.

One child then asked what would happen if the jar was turned upside down. We all watched when the jar was turned upside down and watched all the colours merge together and a nice turquoise colour was created. However our experiment concluded that once the jar had been shaken that the liquids would not go back to their original layers straight away but instead stay mixed up together. Over several hours the liquids separated again.

The children enjoyed their rainbow in a jar science experiment, why don’t you try it at home with your little one.

Super Science!

This morning in the Discovery room the boys and girls took part in a science experiment. This experience was to introduce the children to the mathematical concept of volume. Within this experience some children practised their measuring skills, while others were encouraged to share  their knowledge of primary colours and what happens when you mix colours together.

Some of the children have been exploring 3D shapes  and shared their knowledge by discussing what 3D shapes the containers represented.

The children listened carefully to instructions while we explained that 500mls of coloured water would be added to every container on the water tray. The children then had to decide if they thought the container had enough space inside to hold the volume of water we were going to be pouring in.

Great fun and giggles was had watching the smaller containers over flow with the coloured liquid.

Lastly,  we mixed the coloured waters together to see what would happen and guess what colours would appear.  Why don’t you try the volume experiment at home?
