In this lesson, students will make a chromatogram of different types of ink. Paper chromatography will be used to detect the different dyes used in the ink. This lesson can be used for both Physical Science and Chemistry classes.

Observe the separation of colors derived from black marker ink by wicking water through a marker line on a paper towel.

In the first part of this lab, you will measure the absorption spectra of two conjugated dyes and compare the results to the theoretical predictions of a particle-in-a-box model. In the second part of the experiment, you will identify...

Students perform DNA forensics using food coloring to enhance their understanding of DNA fingerprinting, restriction enzymes, genotyping and DNA gel electrophoresis. They place small drops of different food coloring ("water-based paint")...

This photo shows a completed chromatography chemistry experiment. The colors have clearly separated from each other along the piece of paper. The original black ink was separated using an ethanol and water mixture solvent.

Hunkin's Experiments is a group of simple cartoon illustrations of scientific principles. Some would work well in the classroom, but others have little value beyond entertaining students. All of the projects are easy to do. This one is a...

Learn about ten different methods of separation of substances.
