Chromatography with markers
How many individual colors make the markers you use?
Purpose:
To find how many hues make up one water based felt tipped marker using, Chromatography.
Chromatography is various ways in which, we use to separate mixtures in order to study them.
The separation allows a solution or mixture to, see through an absorbent ( such as clay, gel or paper) so each compound becomes absorbed into a separate often into multi colored layer.
How are markers made?
First a plastic resin is used to make the barrel, caps and end plugs. Then crayola puts the logo and other marks on the outer barrel.
The marker hopper loads the empty barrels onto the assembly line. A machine assembles the marker. Then the ink is put into the marker. The back plug is used to seal off the marker. After the back is sealed a nib is placed on the end and and the cap follows.
Hypothesis
Each marker will consist of at least 3 individual colors.
Materials
1) First and ½ of an inch of water to the bottom of the glass. Use the ruler for measuring.
2.)Cut the coffee filters into long strips an inch wide. Cut as many strips as you do markers.
3) Take one of the strips and color a dot about 1 inch from the bottom of it. Use the ruler to measure.
4.) Gently place your strip into the glass filled with water, lean the strip along the edge of the glass so its at a slight angle. make sure the water level is below the colored dot.
5) Wait a few seconds and the water should start to rise up the coffee filter strip.
6) As the water climbs up the filter, it will pass the dot. When it passes the dot, the ink will be carried up. This is the time when the ink will separate.
7) Repeat the steps above for each colored
