- Animals Week 6 Directions 1.Prepare your desk for science. 2.Use voice level 2 (conversation) to discuss this question: What is a vertebrate? What are the 5 groups? What are examples of each? If you have OLD homework or quizzes to turn in, please put them on the desk up front.
- Slide 2
- Targets & Warm Up Targets: Students will classify animals based on their structures. Warm Up: What does classify mean?
- Slide 3
- Classify Classify : arrange (a group of people or things) in classes or categories according to shared qualities or characteristics.
- Slide 4
- Vertebrate An animal that has a backbone vertebra (noun): one of the small bones that are linked together to form the backbone
- Slide 5
- Invertebrate An animal that does not have a backbone

- 5 major invertebrate groups (there are more, but these are some of the main ones) Arthropods Sponges Sea stars Worms Mollusks
- Slide 8
- Arthropods Largest group of invertebrates Jointed legs; legs and bodies divided into sections Covered by a hard, lightweight outer skin called an exoskeleton Examples: insects, spiders, crabs, shrimp
- Slide 9
- A spider molting, or shedding, its exoskeleton so it can grow. A cicada molting, or shedding its exoskeleton as it finishes its life cycle.

- Cicada
- Slide 11
- Sponges Have many pores Live permanently attached to a place in the water Examples: Barrel Sponge Branching Tube Sponge
- Slide 12
- Sea stars Some have spiny skin Able to regenerate (grow) new limbs Examples: sea stars
- Slide 13
- A sea star's skeleton is made up of many plates that move like flexible joints
- Slide 14
- Worms Some have bodies made of segments Other have simpler bodies Examples: earthworms, leeches, tapeworms
- Slide 15
- Mollusks Have soft bodies May have a shell or shells Examples: snails, oysters, squids, octopuses
- Slide 16
- What type of invertebrate is it?
