Dr. W. Crone (303 FTZ, 629-7439, cronewil@hvcc.edu, http://www.hvcc.edu/academ/faculty/crone/index.html)

Laboratory is worth 25% of the course, with a total of 180 points. This point total will be distributed as follows in my labs:

100 points

from the ten best 10 point quizzes on previous week's lab (labs before Thanksgiving)

30 points

from six 5 point dissection grades:

cnidarian (jellyfish and sea anemone); roundworm; mollusc (clam and squid); annelid (earthworm, clamworm, leech); crayfish; and echinoderm (sea star and sea cucumber)

20 points

from article/web site abstract on an invertebrate phylum

30 points

on comprehensive lab final

180 points total for lab.



Quizzes will be given at the beginning of the lab. These will cover the material assigned in the lab manual and the lab handout. If you miss lab that week, you lose the chance to take that week's quiz. I will be dropping two quiz grades to keeping with that policy.

Dissection grades will be given to the entire group working on individual specimens. The grade will be determined by how the group is prepared, how the group follows the directions in the lab handout and lab manual, care in dissection (don't be paralyzed trying to make the perfect cut, but do not slice your specimen into ribbons either), and instructor's sense of a group's understanding of the goals of that dissection. You will be given credit for a dissection score if you miss lab that week, but make it up with me within two weeks of your return to class.

A laboratory article/website abstract is your chance to go the library, find an article on an invertebrate/protist phylum that interests you, or go online and find an interesting website, and write up the following:

a) complete bibliographic citation for either article or electronic source; one good starting point for appropriate web sites is the University of California Museum of Paleontology:


b) one to four paragraphs that summarizes the article/web site in your own words

c) up to one paragraph that shows how the article, in some way, assists the lab time in describing//adding information about that phylum (e.g., an article about tapeworm infections could be related to the tapeworm structures seen in the flatworm lab)

d) a copy of the article/web site printout attached to your report. You will be dealt with severely if you rip an article out a library journal--it doesn't cost too much to make a copy.

See"Additional course information sheet, Bio 03050" for approaches to bibliographic citation. For citation of electronic material, check out style guides, e.g., URL: http://www.columbia.edu/cu/cup/cgos/idx_basic.html

This is to be typed and is due no later than Tuesday, Week 13, 11/23 at 4 PM at my office (last day of classes before Thanksgiving vacation). Certainly, feel free to hand your report in early, as there will be no credit given to those who hand it in late! I will be glad to go over rough drafts with you during office hours or appointments.

PLEASE NOTE: you will need to confirm your article/website selection with me beforehand, as it will be"first come, first served" choices of the different phyla (I will allow two individuals per phylum). We will be covering the following protist/invertebrate phyla in lab in the following order, with an example in parentheses:

  1. Sarcomastigophora (amoeba)
  • Apicomplexa (malaria parasite)
  • Ciliophora (paramecium)
  • Porifera (sponge)
  • Cnidaria (jellyfish)
  • Ctenophora (comb jelly)
  • Platyhelminthes (tapeworm)
  • Nematoda (roundworm)
  • Rotifera (rotifer)
  • Mollusca (clam)
  • Annelida (earthworm)
  • Arthropoda (insect)
  • Echinodermata (sea star)
  • After Thanksgiving, in the fifteenth week of the semester (12/6-12/10), we will have a lab final in which students will be expected to identify any of the organisms seen in lab before Thanksgiving by (common) name and phylum. There will be a word bank for each category on the test sheet. We will spend week 14, the week after the Thanksgiving break, reviewing these organisms during lab.
