Activities for Kids: Understanding Plants & Colours

Every once in a while we like to do a learning activity that is somewhat outside the box. This week, one class was working on understanding colours and understanding how primary colours made secondary colours.

The second class was biology understanding how plants processed water.

So, to make it fun to learn both, this is what we did:

We took a bouquet of white carnations, some small vases, food colouring and some water.

We put blue and red in two different vases for primary colours. Then mixed blue and red to make purple and the last one was yellow and red mixed to make orange. By putting the food colouring in the water it show how plants “drink” and the colour moves up the stem to the petals, eventually changing the petals to the colour of the water.

Then we watched the process evolve over the next 24 hours.

The above photos were taken in 6 hour increments.

And 24 hours later I get a nice and colourful bouquet for me :
