Materials
- one pack of Non Toxic Crayola Markers (original)
- one metric ruler
- pack of Melitta Basket Coffee Filters
- one pack of Mr. Sketch Scented Markers
- one pair of scissors
- one roll of paper towels (any kind)
- one bowl (any kind)
- water
- timer
Steps
- Take the scissors and cut the coffee filters into strips four inches long and one inch wide until you have six. (using ruler)
- Fill the bowl with water until it is 1/2 way full.
- Take the red marker and draw a line, one centimeter thick across one filter. The line should be one inch from the bottom using the scented marker. Do the same with the non-scented red marker on a different filter strip that you made in step one. (see picture)
- Repeat step two with black and green scented and non scented markers until you have a setup that looks like this.
5. Keep the markers on top of the filter it goes with to avoid confusion, or label with pencil at top. No, pencil will not affect your chromatography experiment.
6. Take the red scented and non-scented strips (scented on the left) and place half of the end nearest to the line of color in the water and wait.
7. When color has crept up enough so that it no longer shows color or reaches the top of the strip, take the strip out and put it on the paper towel. Remember to keep the marker the strip goes with below the strip.
8. Repeat steps 5-7 with black and green markers.
9. Let results dry. (10-15 min using timer)
10. Record your data and results.
