3. Learning Goals We are / will be learning to…
Analyze the risks and benefits of human intervention (e.g. pesticide use, fish stocking, tree planting, antibiotic use and creation 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

4. Yesterday’s Recap Bacterial Lab (collecting cultures) Viruses
What is it: microscopic organism consisting of genetic material (RNA or DNA) surrounded by a protein, lipid (fat), or glycoprotein coat.
Exists between living and non-living (lacks characteristics of six Kingdoms)
Parasitic existence
Examples: Measles, AIDS, SARS
Characteristics: Capsid, nucleic acid
Shapes
Specificity: Viruses must enter cells, are generally selective and only enter specific hosts
Reproduction: Four stages: Attachment and entrance; synthesis of protein and nucleic acid units; assembly of the units; release of new virus particles
2 Cycles: Lytic: Cell bursts open; Lysogenic: Cell breaks open

What does streptobacilli and staphylococci look like:
Why is algae not Planate? What are the characteristics?
Algae = Protista
Single celled (Plantae are multi)
Both plants and algae:
Eukaryotes
Autotrophs
Asexual or sexual

8. Bacterial Cultures Lab
We will be looking at our cultures to see if and what type of bacteria our cultures have grown
We will be discussing lab report expectations / exercises
Bacterial Cultures Lab

9. Lab Report Activity Sheet
Formal Cover Page, Introduction ( includes a purpose, hypothesis and prediction), Methods/Experimental Design, and Conclusion
Attach the Activity Sheet as an Appendix
Lab Report

10. The Hypothesis and Prediction
Hypothesis: The focus of the researcher’s “belief” about what they think will happen:
“It is hypothesized that there will be harmful bacteria present in the girl’s bathroom toilets, on a lock on a locker and on a cell phone. It is further believed that there will be more bacteria on the phone than in the bathroom or on the lock.”
Prediction: Specifies the exact outcome expected and the reason behind it. (try “if, then, because”)
“If there is harmful bacteria present in the…, then the cultures will reveal more harmful bacteria present on the …. than the This will occur because….”
The Hypothesis and Prediction

11. Viruses in the News The class will separate into groups of 5.
Each group will receive an article that they are responsible for reading, summarizing and taking a stand on.
Each group will informally share their ideas with the class.

12. How are the two types of bacterial reproduction (Binary Fission and Conjugation) different? Explain briefly.
