Instructional Ideas

  • Learners may struggle with classifying and understanding protists; spend time using microscopes, looking at the variety of organisms found within this kingdom
  • Have pupils fill in a table or note sheet of characteristics of these three groups of organisms
Classroom Considerations

  • Video 35 in a series of 40

  • Includes a table of contents, allowing teachers to show only specific segments or replay parts scholars found confusing

  • The video moves quickly through a large number of organisms and information, which may overwhelm some learners
