Plants from Balclutha Primary School science garden.

Chemistry outreach spent a session with room 10 and there teacher Jenny Harris looking at the colours we could make using plants from the science garden and some dilute acid and base.
A range of flowers we used
 The plants have one colour in acid and another in base but by mixing the solutions up we found they could create a range of colours.
Ladies Mantle
 Most of these plants worked nicely, although during the course of the experiment some colours were made and then used up ...
purple iris

Rhododendron
Rhododendron has a different dye than most of the other plants so it can only give a range of reds/ornages rather the the variety of other flowers.
Azalea

Lavender 
The colours from lavender didn't come out too well but in real life there was a lovely range of blue/green and green colours.
Purple pansies
