Monomers and Polymers: In Our Own Words



As you have read and as we have just learned,
polymers are made of monomers (or monomers
make up polymers… however you want to think of
it).
This is sort of an easy concept, but often hard to
understand when we start talking about chemical
compounds.
SO…. Put this into your own words…




3 Chemical Indicators in this Lab:




Chemicals that indicate the presence of a certain substance by changing
color when they are in contact with that substance.
A change in color = Positive Result (the substance is there)
NO change in color = Negative Result (the substance is NOT there)
Benedicts Solution: Changes color when it comes in contact with a
Monosaccharide like Glucose
Iodine: Changes color when it comes in contact with a Polysaccharide like
Starch
Buiret Solution: Changes color when it comes in contact with a Protein
Negative Control = Water


The variable that is the same for all test trials. It is guaranteed to give a
Negative Result
Why use water?


Why must we do Part I BEFORE Part II? What does Part I tell us so
that we can do Part II?
 Note: in Part II you are completing the SAME procedures for Part
I, BUT you are using McMush instead of the pure solutions… so for
every test, you will test the McMush and the Water
Procedural Notes:
 Each team member should be the leader for 2 of the 4 tests
 When using the Hot Plate and Boiling the water - NO Messing
