MM 1.6: Nanovision Models of Chromatography
Objective: KWBAT create a digital model to represent what is happening to molecules on the nanoscale when they separate during a chromatography experiment.

1

Below are three different models scientists could draw to show water molecules.

What do the three models of water molecules have in common?

This model shows sugar and water mixing together.
