In this model, each cup contains a different substances (pasta). How many substances (types of pasta) do we have here?

Picture 1

Make observations! What do you see on the chromatography strip?
(HINT: What has happened to the water? What has happened to the food coloring?)

0

Picture 2

Make observations! What do you see on the chromatography strip?
(HINT: What has happened to the water? What has happened to the food coloring?)

Picture 3

Make observations! What do you see on the chromatography strip?
(HINT: What has happened to the water? What has happened to the food coloring?)

Based on these observations, is the food coloring a substance or a mixture?

0

How do you know? Explain your answer for number 14.

Jamie did a chromatography experiment on a marker, and a picture of her chromatography strip is to the right.
Why did the colors separate the way they did?
