  1. Amphibians and Reptiles Chapter 18 Section 2 6th Grade

  2. Do Now… • If fish were to live on land, what adaptations would they need to survive?

  3. Do Now… • Complete another mealworm observation. Work on lab questions and draw a picture if possible.

  4. Objectives Students will… • Describe how amphibians have adapted to live in water and on land • Identify the adaptations that allow reptiles to live on land

  5. Amphibians • Definition: animals that spend part of their lives in water and part on land • Origin of the word “amphibian”- from the Greek word amphibious which means “double life” • Examples: Frogs, Toads, Salamanders

  8. Reptiles---Unique Characteristics pg. 538

  9. Reptile Adaptations pg. 539

  10. Videos • Reptiles and Amphibians part 1 • Reptiles and Amphibians part 2 • Reptiles and Amphibians part 3 • Reptiles and Amphibians part 4

  11. For Next Time… • Read pgs. 535-539

  12. Frog Metamorphosis and Reptiles and Amphibian Review Chapter 18 Section 2 6th Grade

  13. Do Now… • What is the difference between hibernation and estivation?

  14. Objectives • Students will • Create a foldable to learn model the metamorphosis of an amphibian

  15. Amphibian Metamorphosis (Frogs) • Create a foldable according to teacher instructions • 1) Eggs- are laid by adult amphibian in the water • 2) Young Larva-are dependent on water. They have no legs and breathe through gills. • 3)Older Larva- body structures are developed that are necessary for life on land including legs and lungs. • 4) Adult- have lungs, legs, breathe through skin and can reproduce. They require water for external reproduction.

  16. Practice Worksheet • With your lab group—complete Reinforcement worksheet on Amphibians and Reptiles

  17. For Next Time… • Read pgs. 541-544 • Define contour feather and down feather on index cards.
