Deconstructing Colours

The kids have been very interested in colour mixing lately and instead of mixing primary colours together to get a secondary colour, I thought we'd deconstruct secondary colours by diluting them with water.

Cadence wrote the name of a colour on a piece of paper towel and we placed it on top of our light table (that was protected with a clear plastic bag). She slowly dropped water using a pipette on the marker and after many drops, the colour became diluted and we could observe the individual colours that had been used to create the secondary colour. They are hard to see in the photos, but as the green diluted we could clearly see the yellow and blue that had been used to create the shade of green separate from each other.  We tried this with many different colours - even black!

I thought it would be fun to document our exploration using a new app called Pic Collage that has lots of potential for sharing information and student creation in the classroom!
