Notes on Module Four: phytoplankton; dinoflagellates and Red Tide; adaptations of organisms; the Galapagos Islands; food webs and energy.
4.02 4.02 Diatoms and Dinoflagellates
Remember one big difference between them:
diatoms have a very special cell wall made of silica, in some cases very beautiful! In contrast, dinoflagellates' cell walls are made of cellulose, like plant cells are (even though they're not truly plants).
Another big difference is that dinoflagellates can take in food,
in addition to making their own. Diatoms can't do that. Finally, while diatoms are the most abundant photosynthetic organism in the ocean, dinoflagellates are the second-most abundant organisms. (I guess that could be a similarity, that together they're the most abundant marine organisms.)
Keep in mind that they are both classified as protists because
they're not clearly plant or animal.
4.03 Chart for the last question.
The goal is to make a chart for question 6 based on Harmful Algal Blooms and how they impact us financially. Some other links for outside Florida.

4.04 Phytoplankton Lab - This is a fun lab for which you get to make a model of a phytoplankton using common materials you find around the house. The goal is not to make a perfect and complicated model. It’s more about the process of creating a model and testing it. Please read and follow the directions carefully. For your report, you will include the following:
A list of materials you used
A paragraph describing how and why you built your model the way you did
A data chart from the trials in which you test your model in air and in water water
A photo of you with your model
And the answers to the analysis questions
Be playful and have fun with this activity!
Please remember that the ideal phytoplankton doesn’t sink, it hovers near the surface of the water so it can have plenty of sunlight.
4.05 Adaptations of Organisms - This is another creative activity. It has two parts, please be sure you do everything. On the Lesson tab, please click on all links and view “A Fish Tale”. Then on the Prepare tab, do the Build a Fish activity. Finally, on the Activity tab you will use the fish you created to write a creative description of it. For your description you get to choose: do you want to pretend you’re describing this fish to scuba divers; or do you want to pretend you’re an n older fish telling the youngsters how their features help them survive? Have fun with it! Check the Evaluation tab when you are finished to see if you’ve done everything required to get the best grade.
4.08 Food webs and energy transfer
You probably learned about food webs long ago, but here we are focusing on energy transfer. Pay attention to the amount of energy transferred at each step of a food chain; and the advantages/ disadvantages of this.

4.08 Food webs and energy transfer
You probably learned about food webs long ago, but here we are focusing on energy transfer. Pay attention to the amount of energy transferred at each step of a food chain; and the advantages/ disadvantages of this.
4.09 Make a Food Web – for some reason, this assignment makes some students nervous. It’s easiest if you can use a program that allows you to manipulate the food web pictures on your computer and arrange your web that way. If your computer doesn’t have this ability, or you don’t know how to use this type of program, now might be a good time to let a computer whiz friend show you how to do it. If you just can’t figure out how to make it work on the computer, then print out a copy of the web and do some good old fashioned cut-and-pasting. But then you’ll need to scan your finished work so you can submit it to me. If you don’t have a scanner at home, chances are good that a friend or neighbor has one and they can scan it and email it to you. If you need to, you can always go to a place like FedEx/Kinko’s. Remember that the arrows should point in the direction of the flow of energy.
4.10 Honors- Invasive Species
Invasive species are a problem everywhere, but especially for us in Florida because we have so many. As you research the problems
with invasive species, choose one to profile. Remember to make it a marine species! Check out:
http://www.invasivespeciesinfo.gov/aquatics/main.shtml ;
or try the Florida Fish and Wildlife Research Institute at: www.myfwc.com/research/saltwater.
4.11 Class Current Event Report - please be sure to follow the instructions and include an article citation. Write the summary in your own words! Then, go to the class Discussion Board and post your summary there. When you submit for grading, write a note in the Student Comments saying when you posted your summary.

This is a picture of a copepod.
This one-eyed crustacean, called a cyclops copepod, is about 0.5 millimeters long and has a black eye (but some have a red eye and grow as big as 5 millimeters long). This image was taken with a light micrograph. Part of the general classification of "sea plankton" and one of the most common components, copepod are found floating on the surface of freshwater ponds.

Recommended Reading: “Grayson”, by Lynne Cox.
Cox is a long-distance swimmer. She wrote a very engaging short book about an experience she had while swimming off the California coast, when she encountered a baby gray whale that had become separated from his mother. There are lovely descriptions of the ocean and the creaturesin it. It’s a great read!
