Science content (2016 curriculum): 
Chemistry: Physical Changes, Solutions, Mixtures and Separating (2, 4, 5, 6)

Fall leaves are such amazing colours. We’ll explore these colours today.
We’ll use a pretty sophisticated science lab technique called chromatography.

Use the same technique to find out what colours the inks in pens are made up from.
