The Classification of Living Things TAXONOMY LEARNING OBJECTIVES

The Classification of Living Things TAXONOMY

LEARNING OBJECTIVES FOR THIS LESSON � Wrap up from yesterday � Learning Goals for Unit � Learning Goals and Success Criteria � Taxonomy and Carl Linnaeus � Linnaean System of Classification � Levels of Taxonomy � Parasites Project - intro � Homework � Wrap Up – Exit Card

IC R B U R JUST A QUICK WRAP UP FROM YESTERDAY… � Shannon Diversity Index: Measurement of species diversity (number of species) while simultaneously measuring abundance (number of individuals) in a given area. � NOTE #1: The higher the value, the higher the diversity. � NOTE #2: You will need to look at your partner’s H’ Value to see how the other parking lot compares to yours. � NOTE #3: Lab due on Friday---let me know if there is a need for an extension TODAY.

LEARNING GOALS FOR BIODIVERSITY UNIT We are / will be learning to… � � � � � Analyze the risks and benefits of human intervention (e. g. pesticide use, fish stocking, tree planting, etc. ) Analyze how climate change could impact the diversity of living things (e. g. Global warming, increase in precipitation) Become familiar with terms such as: species diversity, structural diversity, bacteria, fungi, binomial nomenclature, morphology Classify, apply, and draw dichotomous keys to identify and classify organisms according to kingdom Explain concepts of taxonomic rank such as genus, species and taxon Compare/contrast characteristics of prokaryotes, eukaryotes and viruses Compare/contrast anatomical and physiological characteristics of organisms representative of each kingdom Explain structural and functional changes of organisms as they have evolved over time Explain why biodiversity is important for maintaining viable ecosystems

LEARNING GOALS & SUCCESS CRITERIA Learning Goals: We are learning to… Success Criteria: I can… Explain concepts of taxonomic rank such as genus, species and taxon � Become familiar with terms such as binomial nomenclature � � Explain how the Linnaeus System of Classification names organisms (scientific name) � Define binomial nomenclature in my own words

TAXONOMY Think of the abundance and types of life on this planet: animals, plants, insects, fungi, bacteria…… HOW DO WE CLASSIFY ALL THESE ORGANISMS? We use the Linnaeus System of Classification made of Latin words created by Swiss botanist, Carl Linnaeus (Linnė).

CARL LINNAEUS – MINDS ON � http: //www. nhm. ac. uk/nature-online/science- of-natural-history/biographies/linnaeus/ (Link courtesy of Natural History Museum) Bryson Pg. 356 -360

LINNAEAN SYSTEM OF CLASSIFICATION �A system of classification that groups organisms on the basis of their structural similarities. This is TAXONOMY. � Binomial nomenclature: Refers to the scientific name of a species. � This uses the genus and species (e. g. Homo sapiens (humans), canis lupus (wolf).

LEVELS OF TAXONOMY (“TAXA”) Organisms can be ordered in a classification system: Broad classification (less similar organisms) www. goldiesroom. org Specific classification (very similar organisms)

PARASITES PROJECT DUE: Wednesday, February 26 th Research a parasite and note its life cycle, host organism, treatment and diagrams. This assignment has 2 components: a report and a presentation to follow. � Report: 1 -2 pages, submitted electronically, references cited in APA format � Presentation: requires a visual aid

HOMEWORK Complete the following: 1. 2. Classification Sheet Biological Classification Sheet Please consider unfinished work homework.

EXIT CARD: Imagine that a new insecticide has been used in a garden that has mistakenly killed many of the bees that are able to visit this garden. What are some of the implications that this could have on the diversity of plants living in the garden? Explain.
