Protists: Helpful or Harmful? (AIG IRP)

Stage 2: Elaborate

Students should begin their research on the positive effects or uses of protists in medicine, industry, and the environment.  The teacher should be prepared to guide students with key search terms like “protists in food chain,” “protists used in human food,” “protists in industry,” protists in medicine,” “protists and oil spills,” etc.  The teacher will also need to remind students to bookmark their sites for future citation or to build their citation page as they work. Previous exposure to protist structures may also be built on through this activity by promoting student research into form and function to explain why they are used in this positive manner—i.e. hydrophilic alginic acid in the cell walls of algae prevents the ice ice cream emulsion from separating.

Students will write their online news articles using yesterday’s research.
