Directions
|
|
|
Study
the instructional material below. Be sure to click on each of the photographs
for an enlarged view in a separate window. The
larger version is necessary to complete the assignment.
It opens in a separate window which can be resized by grabbing the bottom
right corner and dragging it. It
can also be moved by
grabbing the top heading bar and dragging it.
Be sure to close the extra window by using the X in IBM, or the close box
in MAC when you are finished using them. |

Introduction
|
|

|
Planktonic
animals are well adapted for living in the open waters of the pelagic environment.
They have unique characteristics that allow them to survive in the absence
of solid ground. In this lab activity you will become familiar with the
characteristics of several defferent types of zooplankton and study their
taxonomic affinities. |
|
Instruction
|
|
|
Examine
all of the photographs of the zooplankton by clicking each of the thumbnail
pictures. Study the descriptions that go with each photograph and pay particular
attention to the shape and identifying characteristics of each. Learn to
match each example with its phylum.
Be sure
to write about what you are learning in the lab section of your notebook.
You will be expected to answer questions about the lab activity during
the lab self test and lab quiz. It helps to have your text and coloring
books open beside you for support.
