LAB STATION 6
Think-Aloud
A student conducts an experiment involving
enzymes. Three test tubes begin PINK in color at
the beginning of the experiment, and all are kept
at room temperature.
All three test tubes contain Oil.
Color changes were notes in test tubes 1 and 2.
Think: What processes have we discussed in this
bundle? (Dehydration Synthesis, Hydrolysis)
***Remember, in Hydrolysis, H2O is added back
into the Polymer to form Monomers. This means
there would be a CHANGE in CHEMICAL
STRUCTURE! And a CHANGE in COLOR!****
