STUDENT WORKSHEET
Lesson 4a: Introduction to Phyto Files
Note: This lesson was developed by Susan Richman, South Portland High School, Maine and is available at
http://www.bigelow.org/phytopia/ideas.html
. It was reformatted and slightly modified by C‐MORE for this kit.
Directions:
1.
Insert your CD. This CD has sound, so you will need to wear your headphones. Insert the headphones into the
headphone jack on the computer. If you are sharing a computer with another student, insert both headphones
into the headphone adapter and then plug the adapter into the headphone jack on the computer.
2.
After the introduction, select “Phyto Files” (located in the bottom left hand corner). The Phyto Files allow you to
view different types of phytoplankton. A list of the species included on this CD is located in the lower right
corner. This CD profiles 36 species. Thousands of species exist, so this is merely a sampling of the organisms.
You can view these organisms in a variety of ways, but not all options are available for every species.
Some Viewing Suggestions:
Give the images and the program time to load. If you click too quickly, you will run into trouble.
If you cannot see the entire organism, or you wish to see a larger image, click
+ .
You may also change the magnification from 10X to 20X to 40X to 100X. If you would like, you can use
the controls to change your field of view and/or center the specimen.
To rotate the image, left click on the picture and hold the button down as you move the mouse.
Remember to “Clear Search” between questions to ensure that all organisms are listed.
3.
First search by attribute. Below the Quick Search box, you will find five different attributes: Shape, Class,
Morphotype, Harmful, and Protrusions. Once you have selected an attribute, the choices associated with that
feature are listed to the left. For example, if you select “Shape”, the choices are circular, feather‐shaped, and
other.
a)
View two circular species and list their scientific names.
b)
View two feather‐shaped species and list their scientific names.
c)
Select “other” and see what pops up. Describe or sketch one of these species.
d)
Click “Clear Search” (above “Shape”). Next, go to “Class.” How many diatom species are on this CD?
How many dinoflagellate species are on this CD?
e)
What are the options under Morphotype? View examples of each morphotype.
