Super Simple Colour Mixing Experiment

Super Simple Colour Mixing Experiment

Yesterday you may have spotted a video on my Facebook and Instagram pages of the children doing a simple colour mixing experiment.

This was really easy to set up and the children had a lot of fun with this and spent a good while playing and experimenting away.

To do this simple colour mixing experiment we used:

I set up three glasses with some water in and food colouring, leaving us with a glass of red, a glass of blue and a glass of yellow water.

I then gave the children a glass of water. They used the pipettes to transfer some of the blue water into the glass and yellow water into the glass, making the water turn green. They LOVED this and the video on Instagram here shows Mr D says wow as he sees it change colour.

This was really easy and very effective using blue and green.

We then moved on to red and yellow and red and blue to make orange and purple. These weren’t’ as clear as making green, but the children could see it was changing colour.

We did this together a few times and then I left them to play with the pipettes and water. It didn’t take long for them to discover that the more blue they added into the yellow and blue mix, the darker the green – much to their delight.

As soon as Damian came home the children relayed the colour mixing to him and I am sure this is something we will be doing again over the coming days. With that in mind I have a couple of these sheets ready from twinkl. Miss E will enjoy doing this colouring sheet which, once she has done it we will pop up on the wall as a reminder. I also plan to get the tuff spot out at the weekend and let them loose mixing up paint. These little display signs might come in handy to prompt them to mix colours but certainly these record sheets will be a good way for them to remember what they have mixed together.

This was a really easy but effective way to demonstrate colour mixing and the children had loads of fun too.

    Such a good activity to show kids how everything comes from three main colours x

    What a great idea! Always fun to find things the kids want to do and are easy (and not expensive) to do. Love the colours!

    That looks like a lot of fun and the children get to learn something too! Mine are a bit older now otherwise i would be giving it a go too!

    This reminds me of science classes in primary school. I always loved learning how different colours could be made!
