difficult to determine especially because there are so many forms that may
not be familiar. Since many
meroplankton are large the reflecting microscope is the most
appropriate for preliminary classification.
Another way to
classify meroplankton is to use an ice tray and a spoon and group them
into the separate compartments.
Then put them into a live mount with a well.
This controls their movement without killing the organisms.
It is instructive to see the organisms alive and mobile to learn
Since meroplankton is
much larger than the previous lab, students can observe them easily in an
aquarium or if they investigate a river or pond on their own.
The key objective is for them to look for segments which then imply
they are arthropods and this may be a clue that they are part of the
