Parts of the Amphibian

Amphibians live a double life — in water as larvae, on land as adults. The word 'amphibian' means 'both lives.' Moist skin is the giveaway — unlike reptilian scales, amphibian skin is slick. Misclassifying a frog as a reptile is caught immediately.

• Framework: Montessori
• Unit: Cultural Studies
• Learning area: Zoology Classification
• Level: Ages 5-6

Objectives

• Identify parts of a frog (head, body, webbed feet, hind legs, tongue)
• Match nomenclature cards
• Understand amphibian life cycle: egg → tadpole → frog
• Distinguish amphibians from reptiles

Materials

• Zoology puzzle of the frog
• Three-part cards
• Life cycle cards (egg, tadpole, tadpole with legs, frog)
• Pond specimens if available

Instructions

1. Bring the puzzle and cards. 2. Name each body part. 3. Match cards. 4. Introduce life cycle cards. 5. Place them in order: egg → tadpole → legged tadpole → frog. 6. Discuss metamorphosis. 7. Compare amphibian skin (moist) to reptile skin (dry). 8. Research a specific amphibian (salamander, toad). 9. If possible, visit a pond to observe amphibians live.

Educator tip

A classroom tadpole-to-frog observation is one of the most memorable experiences in primary science. Run it for weeks; photograph daily.

Assessment

Note life cycle sequencing, trait identification, and distinction from reptiles.
