Who Done It?
Pick and choose which activities to include in this crime scene investigation. Junior detectives can examine fingerprints, DNA, blood samples, or bone structure. The plan suggests you have teams solve a mystery, but it does not give you...
Curated OER
Chromatographic Separation of Methylene Blue and Sodium Fluorescein
Students determine the best solvent system for separating a methylene blue/sodium fluorescein mixture by thin layer chromatography. They conduct an initial TLC separation using ethanol and a different solvent mixture and analyze the data...
Curated OER
Leaf Chromatography
You can bring science alive for students with these lessons on leaf pigments.
Curated OER
Thin-layer chromatography
Students produce chromatograms of various vegetable extracts and standards. Using a flat bed scanner, they create a database of the results.
Royal Society of Chemistry
Chemistry Masterclass—Chemistry Outreach
Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...
Curated OER
Paper Chromatography
Students participate in an experiment determining how to separate a mixture of dyes in water-soluble ink.
Curated OER
Cell Structures and Their Functions
Life science learners investigate live cells. They examine wet mount slides of cyanobacteria and Elodea plants. They peer into the dynamic microscopic world of protists. Afterward, they construct a model of a cell, including rudimentary...
Curated OER
Separation of Unknowns in a Liquid
Students identify chromatography as method of separating the components of a liquid. Students discover that dyes are composed of more than one component in achieving a particular color in these lessons on paper chromatography.
Curated OER
Wolf Pack in a Bottle
High schoolers participate in an activity of a mock electrophoresis using paper chromatography to study DNA and genetic restriction mapping.
Curated OER
Molecular Evolution in Plants
Students are using a paper chromatography study that is suitable for introductory biology. The absorption spectra studies and gel electrophoresis studies are appropriate for students who have complete both introductory biology and...
Curated OER
The Perils of Drinking Water
Young scholars determine the presence of drugs in water. In this chemistry lesson, students experiment on water samples using thin layer and column chromatography. They determine the concentration of drugs present using graphical analysis.
Curated OER
Chlorophyll
Students use thin layer chromatography, TLC, to separate various pigments found in plants.
Alabama Learning Exchange
What Color Are The Leaves?
Young scholars identify the colors in leaves. In this chromatography lesson, students read the book Why Do Leaves Change Color? and construct chromatography strips to identify the colors of leaves.
Curated OER
Thin Layer Chromatography (TLC) Separation of Plant Pigments - Chlorophyll, Carotene
Young scholars use TLC separations to identify various substances. In this chlorophyll lesson students separate pigments found in different plants.
Curated OER
Ink Analysis and Thin Layer Chromatography
Students 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
Can Chromatography Separate A Pigment?
Students separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.
Curated OER
DNA Fingerprinting
Middle schoolers experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
