An lab experiment where students see how molecules move by doing paper chromatography. Site includes student handout and teacher presentation.

To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink. They use...

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...

Using simple household items like M&Ms and coffee filters, you can demonstrate paper chromatography. This simple lab will show you the dyes that make up the different color coatings on M&Ms.

One of the characteristics that makes M&Ms so popular is dye that colors the hard shell, and of course the chocolate. But, many are unaware of what dyes are used to make those colors. This day long lab uses paper chromatography to...

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,...

This lesson plan can be used to illustrate the principle of electrophoresis without the equipment. Paper chromatography can be used to separate dye just like electrophoresis will separate DNA. The lab also covers DNA analysis for an...

A lab activity that introduces chromatography using markers, plus water and acetone as the solvents. Students will take measurements to compare the mobile and stationary phases of the inks, and find the polarity of the inks and solvents....
