Station #1
Iron (Fe) in Cereal Lab
Iron (Fe) is essential for healthy living and must be obtained from our diets. There are various forms of iron,
some of which are more important than others. Because iron is so important for good nutrition, it is often
added to some foods. This lab examines the iron content of breakfast cereals. Can you separate the iron
from the cereal?
1. After the experiment, explain the results.

Station #2
Separating Mixtures Lab
Evaporation is where a substance will change from a liquid to a gas. For instance, water can turn from a liquid
to a gas by increasing the energy.
Magnetism is the properties of attraction possessed by magnets. Substances that contain iron, steel, cobalt,
and nickel are attracted to magnets.
3. How did you separate the iron fillings from the mixture?

5. How did you separate the salt from the solution?
Station #3
Chromatography
Using chromatography we can find out how many components are in paint, inks, markers as well as in natural
dyes, leaf extracts. As long as mixture is colored we can see their components. Colorless mixtures can also be
separated with paper chromatography, if we can visualize separated compounds with colored chemical
reaction(s).
Chromatography is separating of mixtures into the components they were originally made of by using a
column of silica or a strip of filter paper.
6. In this lab, what was the solvent? __________________________________________________
7. What colors created each of the colors of ink? Describe your observations.

Station #4
Settling
Settling is to cause a substance to be made clear by sediments separating.
In this lab, you will see how substances separate through settling.
8. Shake the jar and time how long it takes for the contents to settle.
