what is crite area of separating water from dye?
Answers
Materials
Paper cups
Coffee Filters (cone type)
Water-soluble markers (marked washable)
Pencil
Binder clip
Procedure
1. Put a small amount of water in the bottom of a paper cup. The water should come up about one quarter inch from the bottom of the cup.
2. Cut the coffee filter paper into rectangles approximately one half inch wide by four inches long.
3. Place a small spot of marker approximately one half inch from the bottom of the paper. The spot should be above the level of the water in the cup.
4. Use a binder clip to attach the filter paper to a pencil, so that the top of the paper is attached to pencil and the bottom hangs free.
5. Place the pencil across the top of the glass so the bottom of the paper is immersed in the water. Be sure that the spot of marker is above the level of the water and that the paper doesn’t touch the sides of the cup.
6. Watch as the water moves up the paper. The spot of color will start to move up the paper as well. If the marker is a mixture of dyes, the different colors will start to separate.
