Curated OER
Paper Chromatography
Small groups of learners 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. Learners...
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
Colored Dots 1
Students observe that colored markers are a mixture of many different colors by performing a chromatography experiment. They make observations, record information, and make generalized inferences from their observations.
Curated OER
Using Chromatography to Identify Unknowns
Students are introduced to the concept of chromatography. They practice using new vocabular and observing experiments. They answer discussion questions to end the lesson.
Curated OER
Chromatography
Students research types of chromatography and complete chromatography experiments.
Curated OER
The Conceptual Theory of Chromatography
Students 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 report on...
Curated OER
Hidden Colors
Students discover presence of different colors hidden in green leaves by performing a chromatography experiment on chopped green leaves.

Chromatography
Eighth graders observe a compound and separate it into its component parts. In this chromatography lesson students complete and activity that demonstrates how mixtures can be separated into components.
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.
Curated OER
Using Ion Exchange Chromatography to Separate Proteins
Students explore protein purification by separating a positively charged molecule, lysozyme, from a negatively charged molecule, albumin, at neutral pH using ion exchange chromatography.
Curated OER
Mixing Colors
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.

Science NetLinks: Color Burst
Students gain experience in asking questions and conducting inquiry by exploring the separation of colors in water and other solvents; to communicate and share findings of student investigations.
Curated OER
DNA Fingerprinting
Middle schoolers experiment with chromatography as a technique which is similar to electrophoresis that scientists use to identify DNA samples.
