Chlorophyll
Students use thin layer chromatography, TLC, to separate various pigments found in plants.
Curated OER
Chromatography
Students investigate the separation of mixtures using plant pigments. Using everyday items, they demonstrate the separation of pigments in plants through the process of chromatography.
Curated OER
Rainbow Electrophoresis
Students are introduced to the principles of gel electrophoresis and also provides an opportunity for students to practice loading gels and prpetting. In this laboratory activity, food color is used to separate into constituent pigments.
