Ecology Expert

YOUR RESEARCH ROLE, ECOLOGY EXPERT:

See your Note Taking Guide below.  Print it out now!  Please use it as you 
gather information.

Everyone first goes to the three websites linked here for every team 
member to see.  View these websites together if possible.   

After that, your job is to gather information on the place of the radiolarian 
in the earth's ecology.  You are responsible for collecting data and images 
for your topic.  

Do that by exploring the websites for your topic linked below.  

Make sure to use the Note Taking Guide for the Ecology Expert (see below).  


Choose at least:
>> four facts 
>> three images
that will support your recommendation, and share them in your group meeting.  

Note:  The slide presentation MUST include a list of sources used.  See the 
SAMPLE SLIDE on the "Files for You" page for an example.  Go to the 
Easybib.com website, linked below, for help in creating a bibliography.

WEBSITES FOR YOU TO VISIT:

"Radiolarians.”  This is the first of THREE WEBSITES FOR EVERY GROUP MEMBER 
TO SEE BEFORE THEIR OWN RESEARCH.  
What are radiolarians?  Did you know they were found in the stones of the 
Egyptian pyramids?  Learn the basics about “rads” here.
http://oceanlink.island.net/oinfo/radiolarians/radiolarian.html
“How the SEM Works”  This is the second of THREE WEBSITES FOR EVERY GROUP 
MEMBER TO SEE BEFORE THEIR OWN RESEARCH.  
Click on “Self-Paced Tour” and go through the self-directed slide show to 
understand what it takes to use a scanning electron microscope.
http://www.mos.org/sln/SEM/works.html
“Animal Images”   This is the third of THREE WEBSITES FOR EVERY GROUP MEMBER 
TO SEE BEFORE THEIR OWN RESEARCH.  
Check out the radiolarians using different powers of the scanning electron 
microscope.  This website has other good information you should also know 
about radiolarians.
http://www.mos.org/sln/SEM/gallery/archive/animals.html
“Radiolarians: Geological Applications”
Scientists are grateful for radiolaria.  “Rads” help scientists understand 
the greenhouse effect and global warming because “rads” are sensitive to 
environmental changes, and have been around for millions of years.

“Introduction to the Radiolaria.”  
Do “rads” have both age and beauty?!  Read this introduction to find out.  
Also learn why radiolarians are important sources of information for 
geologists.

“Radiolaria”  
Scroll halfway down this page to the “Images” portion and check out all the 
radiolaria!  Each specimen has a description, including where it came from, 
its size in microns, and whether a light microscope (LM) or scanning electron 
microscope (SEM) was used.  How many of these images will you include in your 
final PowerPoint presentation?
