  1. Birds Chapter 18 Section 3 6th Grade

  2. Do Now… • Describe the steps of frog metamorphosis.

  3. Objectives Students will… • Identify the characteristics of birds • Describe the adaptations that birds have for flight • Explain the function of feathers

  4. Characteristics of Birds • 1) Endothermic (warm blooded) • 2) two wings • 3) two legs • 4) covered mostly with feathers • 5) Bill or beak • 6) Lay a hard-shelled egg

  5. How Birds are Adapted for Flight • Strong, light skeleton • Tail vertebrate joined for stability • High-energy diet • Strong, efficient heart • Specialized lungs connected to air sacs

  6. Functions of Feathers Down Feathers (4 characteristics) • Trap warm air near body • Under contour feathers of adults • Cover bodies of some young birds • Fluffy Contour Feathers (4 characteristics) • Give birds streamlined shape • Barbs branch off main body • Colors attract males • Camouflage protects from predators

  7. Three Reasons Why Birds Preen • 1) To clean feathers • 2) To organize feathers • 3) To spread oil to keep skin soft and prevent feathers from becoming brittle

  8. Videos • Bird Evolution and Adaptations • Amazing Birds 1

  9. For Next Time… • Complete Self Check Questions #1-3 pg. 544

  10. Flying Paper Birds 6th Grade

  11. Check Now… • Review Self Check Questions #1-3 pg. 544

  12. Objectives • Students will… • Create paper airplanes that model birds in flight • How Bird Wings Work

  13. Flying Paper Birds Types of Flight • Gliding-In gliding flight, a bird's wings deflect air downward, causing a lift force that holds the bird up in the air. When a bird is gliding, it doesn't have to do any work • Soaring-Soaring flight is a special kind of glide, in which the bird flies in a rising air current. Because the air is rising, the bird can maintain its height relative to the ground. (Vultures and Hawks) • Flapping-The wings flap with an up-and-down motion. When the wings move up and down, they are also moving forward through the air along with the rest of the bird.

  14. Bird Paper Airplane Types Follow Directions on Worksheets to create the following airplanes • 1) Straw Flyer Airplane • 2) Falcon Airplane • Begin completing activity worksheet with your lab group • Together as a team you will measure the distance and time of your airplanes in flight

  15. For Next Time… • Complete Reinforcement Worksheet on Birds • Bill Nye- Amphibians
