Microscopes should be
a fun experience for students.
Unfortunately students when they see something under the microscope want
it identified. This sometimes
is a challenge to teachers who are unfamiliar with pond life.
The material included in this section is more for a reference than
anything else. It helps
students read a little about the organism.
However, the vocabulary may be above their head, but if interested
it gives students a way to describe that feature.
This should not be tested as much as helping them give a name to
unknown organisms. It is like
the first time you saw a cow and associate the word with the object.
Students should be
able to spend an entire lab on looking at holoplankton.
Since holoplankton tends to be smaller than meroplankton you can
use both the transmitting and reflecting microscope.
The transmitted light microsope however, is the better type of
microscope and using the demoslides or wetmounts is the best slide
techniques. If you are short
on time and have several classes, the demoslides is the preferable method
since successive classes can see them without spending a lot of time on
