Dye Detective
Oregon Museum of Science and IndustryAdd to list DetailsLearners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it. The...
Dye Detective
Oregon Museum of Science and IndustryAdd to list DetailsLearners analyze mixtures of dyes using filter paper chromatography. They place spots of the different dyes at the bottom of a piece of filter paper, and hang the paper to touch the surface of...
Chromatography Can Separate!
Mount Holyoke CollegeAdd to list DetailsIn this chemistry activity, learners use thin layer chromatography to determine the molecular composition of different markers. First, they use pure rubbing alcohol as the liquid phase, then...
Busted by Biology
Oregon Museum of Science and IndustryAdd to list DetailsIn this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes. In the first experiment, learners extract DNA from...
Column Chromatography
The ExploratoriumAdd to list DetailsIn this activity, learners separate the components of Gatorade using a home-made affinity column. In doing so, learners model the basic principle of affinity chromatography, a technique used to...
Light is Made of Colors
Mount Holyoke CollegeAdd to list DetailsLearners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters. Natural light (sun) and artificial light (lamp, candle, LED) sources are...
Separating with Chromatography
Mount Holyoke CollegeAdd to list DetailsIn this experiment, learners separate different types of molecules in marker inks (using a technique called "thin layer chromatography"). Learners mark dots at the bottom of a strip of...
Chromatography
COSIAdd to list DetailsIn this activity (page 3 of the PDF), learners will observe a physical change. They will be astounded to find out that pens and markers of a seemingly single color can actually be made of multiple...
Black Magic (Color Chromatography)
The ExploratoriumAdd to list DetailsWith a coffee filter, a black marker, and a cup of water, discover the secret colors hidden in black ink. This activity explores capillary action--how water moves up paper--and chromatography--how...
Close, Closer, Closest
National Health MuseumAdd to list DetailsIn this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA. Learners examine coffee filter strips, each dotted...
