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

• This video is hosted on YouTube

Pros

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

Cons

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