What is an Animal? 6th Grade Notes pgs. 498-500 Symmetry Foldable
Do Now Together (with your lab group) Name whether the following animals are invertebrates or vertebrates. • Sponge • Dog • Horse • Worm • Scallop • Squid • Robin • Jellyfish • Dolphin
Objectives Students will • Identify the characteristics of animals • Differentiate between vertebrates and invertebrates • Explain how symmetry of animals differs • *Review vocabulary index cards
Symmetry • Symmetry refers to the arrangement of the individual parts of an object that can be divided into similar halves. 3 Types of Symmetry • Radial • - Body parts arranged in a circle around a central point • -Examples: jellyfish, sea urchins and sea anemone
Symmetry • Bilateral • -Body parts that are nearly mirror images of each other. A line can be drawn down the center of their bodies to divide them into two equal parts. • -Examples: Grasshoppers, Lobsters and humans • Asymmetrical • -Body parts that cannot be divided into similar halves • -Example: sponges
Animal Classification • Invertebrates are animals that do not have backbone. About 97% of all animals are invertebrates. Groups of Invertebrate Animals
For Next Time… • Self Check Questions #1-3 pg. 500 in science notebook due Monday. • Test signed by tomorrow homeroom (last chance!) • Bats presentation tomorrow at 9am with Mr. Anderson
