Key Concepts

  • Apes lack tails.
  • Apes are classified into lesser and great apes.
  • Humans are classified as great apes.
  • Evolutionary classification

Learning Objectives

  • Students will be able to identify the absence of a tail as a key characteristic of apes.
  • Students will be able to differentiate between lesser and great apes, providing examples of each.
  • Students will be able to explain the classification of humans within the great ape family.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they know about apes. Show a picture of an ape with a tail and ask if it's accurate. Introduce the Khan Academy video 'Ape Clarification' to address misconceptions.
  • Video Viewing (3 mins)
    Play the Khan Academy video 'Ape Clarification'. Instruct students to take notes on the key characteristics of apes and the classification of lesser and great apes.
  • Discussion (10 mins)
    Facilitate a class discussion based on the video. Clarify any confusion regarding ape characteristics and classification. Emphasize the evolutionary significance of these classifications.
  • Activity: Ape Classification Chart (15 mins)
    Have students create a chart comparing and contrasting lesser and great apes. They should include examples of each, physical characteristics, and habitat information. They can use online resources for additional information.
  • Conclusion (7 mins)
    Review the key concepts of the lesson. Reiterate the defining characteristics of apes and their classification. Briefly discuss the broader context of primate evolution and human placement within it.

Interactive Exercises

  • Ape or Not?
    Show images of various primates, including apes and monkeys. Students must identify whether each animal is an ape and justify their answer based on the presence or absence of a tail.
