Laboratory assistants Chinwe
Korie and Michael Mohn are shown preparing materials for the students
of the Bio. Sci. 10 course.
Jason Ryan, Bio. Sci.
laboratory assistant, is harvesting and fixing (stopping
cell growth) onion root tips. These will be stained by the students
in the laboratory and viewed under a microscope. Students will
be able to identify various mitotic stages.
One of things we do on a regular basis is run each
lab experiment before the students
do . This is important because the students mostly have only
one opportunity to run the experiments (during their specific block
of time, during their lab section) and so these "pilot tests"
allow us to work out any potential problems ahead of time.
Sciences Laboratory Assistant is shown here carrying out a pilot
test of an upcomming lab on Enzyme Activity
The concentration of enzyme (in this case amylase) and
substrate (in this case starch) must be precise so that a gradient
of digestion can be observed by the students within their
given laboratory period.
|This shows the results of
the experiment, if carried out properly. The left hand side shows
starch being digested by the enzyme amylase - as indicated by
an increasingly negative IKI test for starch (read left to right).
The right hand side shows an increasingly positive Benedict's
test - as starch is being digested into glucose molecules (read
right to left).
