Today I'm going to talk about an activity I did last week, which the children thoroughly enjoyed. At the moment we are looking at the world around us, and in the previous lessons we had been talking about the weather. In the lesson in question we were looking at primary colours and the other colours that can be formed by these. Some of the children were aware that mixing colours formed new ones, but others were finding it hard to guess which colours would be created. So we did an experiment to see how by using only three colours: RED, BLUE and YELLOW, we could make others such as orange, green, purple and pink.
What you need:
- A bowl
- red, blue and green food coloring
- washing-up liquid
I then gave the children a worksheet where they had to predict what they would see.
We carried out the experiment twice, in order to see if there were any changes between the two bowls.
The children commented on the new colours that emerged and even compared the second bowl to a planet!
These pictures show how the two bowls developed:
The children then completed the second part of the worksheet, by choosing one of the two bowls and drawing what they had seen.
The final activity was noticing which colours merged together to form new ones.
The children had lots of fun and were really engaged - one of the few times I have managed to get them all standing still around the table quietly!
