In Mull this week we conducted a very interesting science experiment in class. We began by asking the question- ‘Why do leaves lose their colour during the Autumn?’. We discussed in great detail the difference between deciduous and evergreen trees and the different seasons. Here is how we tested our experiment:

1) We gathered some different coloured autumn leaves.

2) We broke them up into small pieces and popped them into 3 different jars organised by colour. We crushed them up with a spoon.

3) We poured in Isopropyl- A mild acid which will help to break down the colours. Then we gently swished it.

4) We wrapped cling film over the top.

5) We placed all three jars into a basin with nearly boiling water poured in.

6) We waited for 30 minutes and then removed the clingfilm and stuck in a coffee filter to absorb any of the colour that we have removed.

The next morning we found some amazing results and recorded them in our science books, take a look at some of our pictures.
