Chromatography

Chroma=colour graphy=writing or a science 

What are pigments?

-Pigments are molecules that absorb, reflect or transmit the light. 

Today we will be doing another small experiment. Using chromatography to investigate the pigments that make up different colours.

Hypothesis: I think the colours will separate based on the different pigments. 

                   What happened?

-The colours separated into a few different colours and climbed up the paper.

What pigments were in the felt?

-In the colour purple there was pink and blue.
