Leaf Chromatography
You can bring science alive for students with these lessons on leaf pigments.
Curated OER
Ink Analysis and Thin Layer Chromatography
Young scholars explain the process of TLC. They identify at least three components of ink. They analyze data and make conclusions based on laboratory observations.
Curated OER
Chromotography
In this chromatography worksheet, students are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.
Curated OER
Separation of Unknowns in a Liquid
Students identify the different components of a given sample using chromatography. In this chemistry activity, students compare paper and column chromatography. They collect data and construct data tables.
Curated OER
Plant Pigment Chemistry
High schoolers discover the roles of pigments present in leaves. They extract and isolate pigments present in autumn leaves using a thin layer chromatography. Very nice lesson and lab!
Curated OER
Relationships and Biodiversity
Students examine diversity on the planet and the differences within a species. In this investigative lesson students complete a lab that allows students to better understand the relatedness between plants.
Curated OER
Molecular Evolution in Plants
Students examine chlorophylls. They explore the absorbing pigments in a variety of plants. Through activities, students determine spectrophotometrically. They compare plant proteins from the family Brassicace to assess the level of...
Curated OER
CSI: Native America
Students discuss the murders of Native Americans in Indiana. In groups, they research and make drawings of the scene as if they were part of a CSI team. They complete any needed experiments to help them solve the crime and create a...
