Presentation Transcript

  1. Arthropods 6th Grade Mini Lab-Observing Sowbugs

  2. Do Now… • Define Regeneration and Arthropods on index cards. • Review Self Check Questions pg. 511

  3. Objectives • Students will… • List the features used to classify arthropods • Explain how the function of the exoskeleton relates to its function

  4. Arthropods • Characteristics of Arthropods • 1) Invertebrates (no backbone) • 2) Bilateral symmetry • 3) Exoskeleton (rigid body covering that protects and supports the body and reduces water loss • 4) Jointed appendages (helps with movement) • 5) Segmented Bodies (head, thorax and abdomen)

  5. Types of Arthropods

  6. Mini Lab: Observing Sow Bugs • Purpose: To observe and identify sow bug reactions to wet and dry conditions • Lab Procedures/Instructions • Safety Precautions • Answer lab questions

  7. For Next Time… • Finish Lab if needed. • Read pgs. 517-518 • Define appendage, exoskeleton and metamorphosis on index cards

  8. Echinoderms 6th Grade Pgs. 517-518

  9. Do Now… • How are centipedes and millipedes different?

  10. Objectives • Students will… • Identify features of echinoderm • Examine the differences between Complete Metamorphosis and Incomplete Metamorphosis

  11. Metamorphosis • Complete Metamorphosis (Bees, Butterflies, Ants, Beetles pg. 513)

  12. Metamorphosis • Incomplete Metamorphosis (grasshoppers, cockroaches, termites, dragonflies pg. 513)

  13. Visualizing Arthropod Diversity • Pgs. 514-515 • Volunteer Readers to share information?

  14. Echinoderms • Examples of Echinoderms: sea stars, brittle stars, sea urchins, sand dollars, and sea cucumbers. • Characteristics of Echinoderms • 1) radial symmetry • 2) spines (for protection) • 3) simple nervous system • 4) No head or brain • 5) Some are predators, some are filter feeders and others feed on decaying matter

  15. Water Vascular System and Cool facts • Water Vascular System- A net work of water-filled canals and thousands of tube feet. • Tube feet help the echinoderm to move and capture prey • Have a unique way of eating---pushes its stomach out and into the opened shell of its prey • Can regenerate lost or damaged parts!

  16. For Next Time… • Complete Self Check Questions #1-4 pg. 518 in science notebook. • Echinoderms Part 1 • Echinoderms Part 2
