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...

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...

Groups use alcohol and chromatography paper to separate the color components of black ink. The purpose of the activity is to allow the class to become aware that mixtures exist in hidden places. 

Students conduct various experiments on chromatography. In this chemistry lesson plan, students distinguish among the different types of chromatography methods. They explain how the stationary and mobile phase interact with each other.

Students investigate the organic acids present in a variety of juices. In this organic acids lesson plan, students read about the effects of organic acids in juices. They use paper chromatography to separate out the acids present in a...

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...

Fifth graders study the scientific method and understand how to apply it.  In this "thinking like a scientist" instructional activity students complete several activities.

High schoolers conduct a lab to determine the best way to separate a variety of mixtures choosing between paper, thin layer and column chromatography. They use chromatography techniques to identify unknown substances and submit a lab...

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...

Third graders use the scientific method as they separate the colors used in ink. In this chromatography lesson, the teacher introduces students to how chromatography is used in several careers, then students perform an experiment to see...

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.

Students investigate chromatography. In this chromatography lesson plan, students investigate a lab set up for chromatography.

In this chromatography activity, middle schoolers are given markers, filter paper and a solvent to separate the pigments found in each marker. Students create a chromatogram for each marker.

Young scholars identify the different components of a given sample using chromatography. In this chemistry lesson, students compare paper and column chromatography. They collect data and construct data tables.

Fifth graders perform experiments with color mixing and color changing. They observe the differences between physical and chemical changes and record their observations in journals.

Learners 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...

Chromatography is a method used to separate mixtures of compounds and to identify each compound in the mixture. You may have separated the different inks in a black marker by using a strip of paper and water. There are many different...

This project will teach you the basics of analytical chemistry, which is a must for students who want to go into chemistry or materials science. The molecules in objects we see all around us are constantly attracting each other....

This lesson focuses on analyzing and identifying substances. Substances can be analyzed using a variety of methods including paper chromatography, gas chromatography and mass spectrometry. After reading about the different techniques,...

Learn about ten different methods of separation of substances.
