2010: Nutrients Activity
Who Stole the Playstation?
•Students will understand
the basic concepts of
different nutrients in
foods.
•Students will chemically
test and compare
different nutrients using
extraction techniques.
•Students will observe
the presence of various
nutrients in foods.
We have been called in by Colby’s Security
Department to help them recover a Playstation 3 (PS3)
that was stolen from their office. The PS3 was removed
at approximately 9:00 PM while the officer on duty was
called away from a game of Grand Theft Auto to
investigate a potentially illegal gathering in one of the
residence halls. The officer noted five suspicious
persons on his way out of Roberts. Fortunately, the
culprit left behind a clue in the form of a crumb of food.
We will conduct an analysis of the snack food eaten by
each suspect to try to match it to the culprit’s crumb.
Note that we will also analyze a donut as a control to
make sure that the crumb wasn’t left behind by the
security officer himself.

the importance of
micronutrients to protect
against diseases like
scurvy.
•Students will test various
beverages for vitamin C
content.
DNA
• High tech: purify from cheek cells,
amplify using PCR
• Low tech: purify from strawberries
or other source

Determining Rh Factor
•Students use their own
DNA as a template for
PCR.
•Students determine
whether their blood type
is Rh positive or negative
after analyzing the PCR
products via
electrophoresis.

from a cheek cell sample.
2010: Microbes Activity
Do you know how fast microbes spread?
•One student is “infected” with yeast and then shakes
hands with a classmate, who shakes hands with a
classmate, and so on. Student then see if their hands
were “infected” by inoculating a yeast growth plate.
2012: Fitness Activity
Healthy Hearts
•Students use heart rate monitors
under various conditions (at rest,
after exercise, listening to music).
