  1. Biodiversity Mrs. Zazzali Room 205

  2. Lesson 1- What are organisms? • Class consensus-period 1 • What are organisms?

  3. Lesson 1-What are organisms? • Consensus Pd. 2

  4. Lesson 1-Pd. 3 • What are organisms? Pd. 3 Consensus

  5. Lesson 1-Pd. 5 • What are organisms? Consensus p.5

  6. Lesson 1 – Pd. 6 • What are organisms? Class consensus says…

  7. Lesson 1 – Pd. 7 • What are organisms? Class consensus says…

  8. What is a habitat? • All classes said… • Place where an organism lives depending on the organism ex. Monkey lives in the jungle • Where a species finds food • Its’ environment and where an organism reproduces, gets rid of waste (Ha Ha pd. 6 ) • Natural home or shelter of an animal • Lives according to their needs • Adapts and responds to environment • And carries out life processes!

  9. What should I know about Taxonomy? • Taxonomy-the science of naming and classifying organisms (Thank you Linnaeus!) • All Taxonomic Categories go from the most broad category to the most specific and include:

  10. The Scientific Name-Avoid the confusion! • Scientists refer to organisms with their Scientific Names to avoid confusion, a universal language. Remember all the confusion when I asked you to find the difference between a cougar, puma and mountain lion. You know now that they are really the same organism or animal known Scientifically as Puma concolar!

  11. Scientific Name cont. • Scientific Name is made of the Genus and species name. The first letter in the Genus is always spelled with an upper case letter and the species first letter is always lower case. The species is the most specific taxonomic category. • Examples:

  12. Lesson 1 Bonus/Challenge Words • Cellular Respiration-cells turning food into usable energy. • Cladogram-branching diagram that shows how species have evolved from a common ancestral line • Digestion-food is broken up physically and chemically and absorbed by the body • Excretion-substance is excreted/let out from the body

  13. Lesson 2 • Compound Light Microscope- Uses 2 lenses and light to make a specimen visible. *Look over your Microscope worksheet, know the parts* • Dry-Mount Slide- A microscope slide on which no water is used. (Our WOWBug slides)

  14. Our WOWBug! • What did we learn? (All Periods-look at blog) • www.zsciencespot.blogspot.com

  15. WOWBug and insect parts • Head- 1st body segment in insects (contain eyes, antennae and mandibles or jaw) • Thorax- 2nd body segment in insects, between the head and abdomen • Abdomen- A segment of the body of many animals, the third body segment in insects

  16. WOWBug

  17. Microscope Views of Specimen-Bonus/Challenge words • Lateral- side view of a specimen • Ventral- abdominal view of a specimen • Dorsal- back view of a specimen

  18. Lesson 3 – Investigating Lumbriculusvariegatus or the Blackworm • What did you learn? • Blackworms can regenerate both head and tail to break free from predators. • Lives in Ponds, Marshes and Lakes in N. America, and Europe. • Contain male and female sex organs. • Tail end used for sensing. • Can have 150—250 segments. • Under a microscope, you can monitor their pulse in bpm’s.

  19. Key Vocabulary • Anterior – toward the front, or head, of an animal body. • Posterior – toward the back end of an animal. • Regeneration – process by which organisms produce new body parts.
