The effects of toxin associated with certain marine algae
Students will be able to research a toxin and the algae that secretes it. Students will create and educational pamphlet using Microsoft Publisher to create an informational pamphlets to warn the public of harmful effects of toxin's produced by certain harmful algae's.
Objectives
Students will be able to identify species of harmful aglae's and parts of the world they inhabit Students will be able to explore the types of toxins harmful aglae produce and their effects on other animals
Materials
1. http://www.whoi.edu/redtide/page.do?pid=9257 2. Computer 3. Micro Soft Publisher 4. access to a printer
Procedure
1. Pair the students in to groups of two or three 2. Allow the students to observe the list of toxins from the U.S. Finfish, Shellfish and Wildlife Affected by Toxic or Harmful Microalgal Species list which can be found at: http://www.whoi.edu/science/B/redtide/species/speciestable.html. 3. Have the student groups choose a toxin 4. Provide them with the following website: http://www.whoi.edu/redtide/page.do?pid=9257 5. Allow them to research their toxin using the website. 6. Students will create an informational pamphlet about their toxin and its effects on the wildlife in the region these harmful algae's inhabit. 7. Make sure students include the pamphlet a. the definition of an HAB b. the name and an image of the organism that produces the toxin c. the location on Earth where these organisms can be found d. the organisms that are primarily effected by the toxins e. how the organisms may be effected by the toxins f. students may also add any interesting facts that they might also learn through the research
