3. Chromatography
I have participated in practical activities to separate simple mixtures of substances and can relate my findings to my everyday experience.
SCN 2-16a
I can differentiate between pure substances and mixtures in common use and can select appropriate physical methods for separating mixtures into their components.
SCN 3-16a
I can participate in practical activities to extract useful substances from natural resources.
SCN 3-17b

4. Chromatography
The mixture is dissolved in a fluid called the "mobile phase“.
This carries it through a structure holding another material called the "stationary phase".
The various constituents of the mixture travel at different speeds, causing them to separate.
