Distance Learning, Paper Chromatography Activity

Description

Chromatography is the oldest documented technique to separate chemical substances. In this activity, students will perform paper chromatography on three individual dyes, along with a mixture of dyes, to determine the composition of the mixture. Students will understand not only the components of a chromatography system, but also why different substances separate and move at different rates within the system. An Instruction Manual and enough materials for 2 groups are included.

Aligned to the Next Generation Science Standards (NGSS)*

Disciplinary Core Ideas: PS1.A; PS1.B
