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

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.
Slide 10
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
Review 1.What is a vertebrate? What is an invertebrate? 2.What
is the major difference in support/structures for vertebrates and
invertebrates? 3.What are the vertebrate groups? 4.What are the
(main) invertebrate groups?
Slide 21
Targets (Revisited) Targets: Students will classify animals
based on their structure.
