MM 1.9: Revising Chromatography Models & Chapter Focus Task

Everything we know about molecules:

Statement A: All molecules of one substance are exactly the same, and they are different from molecules of any other substance.

Statement B: The properties of the molecules of a substance do not change.

Statement A: All molecules of one substance are exactly the same, and they are different from molecules of any other substance.

Statement B: The properties of the molecules of a substance do not change.

Explain why the answer you chose for Question 1. Use Statement A and Statement B to write your answer.

Statement A: All molecules of one substance are exactly the same, and they are different from molecules of any other substance.

Statement B: The properties of the molecules of a substance do not change.

Sentence starter:

The __ model is the most accurate (correct) because _

Drawing Chromatography Models

Modeling 
Create a model that shows the location and arrangement of the dye molecules in the chromatography experiment before and after the chromatography paper is placed in the water.

Draw your chromatography model to show what happened to the molecules before and after adding water to the food coloring.
