An activity guide for teaching children about chromatography, a chemical process used to separate substances into their individual components. The activity includes making a chromatography 'flower' or 'test strip' using coffee filters, markers, water, and other materials. The children will learn about the different phases of chromatography, the role of solvents, and the separation of dyes. The activity is suitable for grades 1-5.

Museum Connection: Diorama halls have excellent examples of art work. Overview of activity: In this activity, we will learn about paper chromatography and along the way we’ll also make a chromatography “flower” Grade Level: Grades 1- 5 Main Idea: Understand that chromatography is the chemistry of taking things apart through the use of colors. Background Info: Chromatography is used to separate a substance into its individual components. There are different phases with chromatography: Stationary (solid or liquid supported by a solid) and Mobile (liquid or gas). One of the most common ways this chemical process is used is through paper chromatography. Most often, it is used to separate out the mixtures of different color dyes. For paper chromatography, dyes are marked out on a designated type of paper and a solvent (coffee filters and water in our case). The solvent should be below the marks of dye. As the solvent travels up the paper, the different components of the dye travel at different rates- the more dye it has the more it will typically. This allows a chemist to determine what components came together to make a dye. http://www.chemguide.co.uk/analysis/chromatography/paper.html Food Paper Chromatography Overview of activity: In this activity, we will learn about paper chromatography and along the way we’ll also make a chromatography “flower” Materials (read step-by-step instructions for exact materials needed) Item Quantity Coffee Filter 1 - 2 per person
Markers (Vis a Vis, washable, permanent, etc) X Scissors X Clear Cups At least 1 per person/test strip Water X Tape X String X Clothespins 1 per paper strip Paper towel 1 per person Pipe cleaner 1 per person Ruler 1 per person Wooden skewer/toothpick 1 per test strip Prep (10- 15 minutes): Gather the necessary materials for the experiment. You should also decide on a design for the paper, for example, making individual “flowers” or test strips. o Flowers are great for younger ages, test strips are great for older ages. For Flowers, you may want to prep coffee filters by cutting a hole in the center and preparing the “paper towel wicks”. For test strips, you may choose to cut your coffee filters ahead of time into strips. Prepare cups and water or have them available when ready as well as prep the drying area. Step-by-Step Instructions: Flowers (15- 20 minutes, drying takes longer):
Test Strips (15-20 minutes, drying takes longer):
b. What is happening to the different colors they have on their test strips?
