What is one of the greatest threats to human-kind?
Why Biology?
• A virus like Ebola?
Why Biology?
• BSE causative agent (called a prion) is a protein that is folded in the wrong way

Biology
• Study of life• Includes– Physics– Chemistry
• All systems– Habitats– Cells– Atoms
Characteristics of Living things
• Uses energy• Respond to their environment• Maintains a relatively constant internal
environment• Information base in the form of DNA• Composed of One or more cells• Evolved from other living things• Highly organized

MYSTERY!
How did 500 people, in 10 days, get Cholera?
What is Science?
Science is based on “knowledge” or “skill”Debate of what science is: Is it mathematical?
Who has the knowledge?• Scientist? Laymen?• Does it depend on what the general population believes?• Does science change?
How is that knowledge verified?Scientific Method: Francis Bacon (1561-1626)
“Baconian Method”
PseudoScience
Scientific Method“Baconian Method”
• Hypothesis• Prediction and testing• Experimental Design• Rigorous Testing• Duplication
Sir Francis Bacon 1561-1626
Lab Period One: Appropriate Scientific Sources
First Lab Period: Who determines what is valid scientific results?
1. What are primary, secondary, and tertiary sources?2. How do you read a peer reviewed journal article?3. How do you find appropriate sources (library)
Homework:
• Find peer reviewed article and write a summary in electronic journal (2-3 sentences)
How do you discern between good and poorly performed science?
Acceptable Resources
• Primary Original source or evidence Peer reviewed journal articles
• Secondary Cite, comment on, or build upon
primary sources Books, scientific magazines
• Tertiary Compilation of primary and secondary sources
How you do discern acceptable resources?
• In a small group check the resources on your desk.
• Which are acceptable for scientific research?
The Nature of Science
• Ethics in experimentation • Science Changes
