  3. Unit 1 Ch 1 Lesson 3How Do Scientists Divide Kingdoms into Smaller Groups? How are lizards & insects alike?

  4. Unit 1 Ch 1 Lesson 3How Do Scientists Divide Kingdoms into Smaller Groups? They are made of many cells. They both eat other organisms.

  5. Unit 1 Ch 1 Lesson 3How Do Scientists Divide Kingdoms into Smaller Groups? How are they different?

  6. Unit 1 Ch 1 Lesson 3How Do Scientists Divide Kingdoms into Smaller Groups? An insect has Three pairs of legs. No bones.

  7. Unit 1 Ch 1 Lesson 3How Do Scientists Divide Kingdoms into Smaller Groups? A lizard has Two pairs of legs. A bone skeleton

  8. Tell your neighbor how insects and lizards are alike and different.

  9. The lion belongs to the following groups:Kingdom Animalia (includes all animals)Phylum Chordata (includes all vertebrate animals, as well as some other more primitive ones)ClassMammalia (includes all mammals)Order Carnivora (includes carnivorous mammals, from bears to raccoons to harbor seals)FamilyFelidae (includes all cats)GenusPanthera (includes the great roaring cats: lions, tigers, jaguars, and leopards)Species leo (lions!)

  11. The smallest classification group is a species. On the chart on p. 25, the only kind of organism in the species is the lion.

  12. Scientific Names Your scientific Name is: Homo sapiens, Which means “thinking man” in Latin

  13. Scientific Names One organism can have many common names. Scientists give every kind of organism its own scientific name.

  14. Scientific Names Always two names. The genus name and The species name. A leopard’s scientific name is: Panthera pardus. A tiger’s scientific name is: Panthera tigris Both are in the genus Panthera Each has a different species.

  15. Changes in Classification The five-kingdom classification system is a tool, not a fact that can’t change.

  17. Changes in Classification About 125 years ago the protists kingdom was added. As scientists learned more, Fungi & Monera were added.

  18. Changes in Classification Today

  19. Unit 1 Ch 1 Lesson 3How Do Scientists Divide Kingdoms into Smaller Groups? Lesson Objectives You will learn: How scientists use traits to divide kingdom. How and why organisms are given scientific names. Why classification changes.
