MM 1.5 - Separating a Food-Coloring Mixture

In the last lesson, you did a __________ experiment using food coloring. When you added the __________ with the food coloring to the water, the water climbed up the strip and brought the dye with it. But, the dye actually __________ into different colors as it went up the strip! From the pasta model yesterday, you know that different molecules can actually be different __________. Today we’ll use another __________ to try to explain how and why the __________ separates as it climbs up the paper strip.

Chromatography / Fan Model

Chromatography is a technique that scientists use to separate mixtures into their parts.
There are three essential parts of a chromatography test.
The test mixture is what is being separated.
The medium is what the test mixture moves through.
The solvent is what helps the test mixture move.
