1. Diversity of Living Things: Dissection Unit
Welcome Back!!
Diversity of Living Things: Dissection Unit

2. Standards:
High School - Life Science 4-1: Natural Selection and Evolution
Students will be able to observe common characteristics such as homologous structures among different classification of organisms.
Students will be able to observe specific adaptations that increase an organism's chance of survival.
Why we dissect in biology:
Dissections are to be done with respect to observe the complexity of life & you will be able to:
develop skills of observation and comparison,
discover the shared and unique structures and processes of specific organisms
develop a greater appreciation for the complexity of life
Your lab grade is largely based on how well you preserve your specimen and document your observations - Purposefully destroying your lab specimen will result in a failing grade

3. HW to prepare for Dissection & Friday Quiz Check
Unit 8: Animal Diversity
Read 23.2 Pages : *Make sure to review and pay attention to the phylogenetic tree: figure 23.7 on pg 703*
Take chapter notes (bullet points, 1-3 important pieces of information per section/paragraph)
Define the vocabulary listed in the title on page 699 (vertebrate, invertebrate, phylum, bilateral symmetry, radial symmetry, protostome, & deuterostome) & answer questions 1-5 on pg 704
Read pg of 23.4 (READ COMPLETELY as we are dissecting an annelid):
Define segmentation & coelom & answer question #3 on page 715

4. Carlous Linneaus
The National Science Foundation’s “Tree of Life” project estimates there are potentially 5-10 million species on this planet, yet only 2 million have been identified.

5. The genus Homo is a latin word meaning “man” or “human”, the species sapien is a latin word meaning “wise”
NOTE:
The scientific name can be abbreviated such as:
H. sapiens
The scientific name is written underlined:
Homo sapiens or H. sapiens
Or italicized:
Genus: always capitalized & written first
species: always lowercase & written second

6. As we go down each level, more and more organisms are removed:
Each level gets more and more specific

8. Practice Dichotomous Key & Classification!

9. In your journal: Document initial observations of jelly bean
Write out path followed from dichotomous key
Write flavored determined
Try the jelly bean, confirm or deny flavored determined
