| Jelly Bean Chromatography |
Spring is in the air, and the stores seem to be full of candy. Candy is a great multi-tasker! It can serve as inexpensive science experiment material, as well as tasty treat when the experiment is over. Materials:
Fold the coffee filter into half. Fold it again one more time. Squeeze some of the pectin (the gooey center) from the colored jelly bean in a line about one inch (2-3 cm) from the round edge of the filter. Be sure to save room for a black line next to it. Squeeze some of the pectin from the black jelly bean in a line one inch (2-3 cm) from the other side of the round edge. Do not let the lines touch each other. Make the filter into a cone shape by securing the edge of the paper filter with the paper clip. Place water in the saucer. Put the round edge of the filter in the water. Let the filter stay in this position for one hour and then observe the results. Colors, or pigments, move at different rates through the paper, carried by the water molecules. When the water moves upward, the pigment soaks into the filter. The different colors settle in various places on the filter because the pigment molecules have different weights. The water will carry the lighter molecular weight molecules farther. Many colors, like black, are actually combinations of many pigments. Do you observe the pigment of your colored jelly bean in your black jelly bean too? Repeat this activity with all the colors of jelly beans in your bag. Which colors traveled the farthest? Which colors seem to be made up of more than one pigment?
