Animals Directions Week 6 Prepare your desk for science. 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.

Targets & Warm Up Targets: Students will classify animals based on their structures. Warm Up: What does classify mean?

Classify Classify: arrange (a group of people or things) in classes or categories according to shared qualities or characteristics.

An animal that has a backbone Vertebrate An animal that has a backbone ver·te·bra (noun): one of the small bones that are linked together to form the backbone

Arthropods Sponges Sea stars Worms Mollusks 5 major invertebrate groups (there are more, but these are some of the main ones) Arthropods Sponges Sea stars Worms Mollusks

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

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

Sponges Have many pores Live permanently attached to a place in the water Examples: Barrel Sponge Branching Tube Sponge

Sea stars Some have spiny skin Able to regenerate (grow) new limbs Examples: sea stars

A sea star's skeleton is made up of many plates that move like flexible joints

Worms Some have bodies made of segments Other have simpler bodies Examples: earthworms, leeches, tapeworms

Mollusks Have soft bodies May have a shell or shells Examples: snails, oysters, squids, octopuses
