Serc: Paper Chromatography: These Colors Do Run

Test differences in writing instruments with this hands-on activity to demonstrate paper chromatography in action. The class performs an experiment on multiple writing instruments and determines the area of separation to discover an...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

High school chemistry class members become "detectives for a day" and use the concept of paper chromatography to analyze a note left at the scene of a crime. Pupils test the ink on the note with a solvent, such as isopropyl alcohol, to...

The Stroop test helps diagnose executive function disorders when used in conjunction with other tests. Reading color words and identifying colors seem like basic skills, but the Stroop test may show otherwise. Scholars work with a...

Your chemistry class is sure to love this experiment on column chromatography, as demonstrated with chalk sticks and felt tip markers. Pupils use sidewalk chalk (another inexpensive form of chalk stick) to demonstrate adsorption and the...

Thin-layer and gas-liquid chromatography are introduced in an intelligible presentation. Paper chromatography is also listed as another type of chromatography, but it is not explained. If you are particular about appearances, there are...

In this leaf chromatography worksheet, students separate the pigments of a leaf using paper chromatography. They answer 4 questions about their results and draw the colors they observe on their chromatogram from the leaf.

Students study chromatography and how they can distinguish between the different pigments in a color.  In this chromatography lesson plan students separate a mixture of dyes in soluble ink then record the colors they see. 

Small groups of high schoolers perform paper chromatography to separate food dyes into their component colors. Students perform the experiment and collect, organize, and represent their data to form an explanation of their outcomes. High...

There's no better motivator than candy! An engaging activity has pupils explore methods for separating mixtures. A two-part lab first explores methods of separation based on size and magnetism. The second activity introduces learners to...
