Agenda
Paper due next Friday

4. I. Misconception 1: Nature of Scientific Knowledge
Tentative- although well supported by evidence
Not proven or absolute
Abandoned or modified with new light or evidence
Confidence in Sci Know
Reflects most current and valid description and explanation

5. C. Examples
Ulcers
Stress medications
Bacteria in stomach
Technology- spontaneous generation- Aristotle “full of soul”
Louis Pasteur’s covered meat jars
Blood Letting –earth, wind, fire, and water
Prevent or cure of diseases
Menstrual cycles
Sneezing
Changing personalities (Egyptians)- Christians “God bless you”
Technologies- microscope pollen, allergies, dust, mucus

6. D. Biology class and Nature of Science
Predetermined Labs
From trial and error
Look for the null, learn from being wrong
Original inquiry

7. II. Misconception about the Work of Scientists (Nature of Scientists)
The roles of creativity and imagination in science
“Imagination is more important than knowledge.”-Albert Einstein
Most technology originates from a fictional concept- What if!?
Inference then tested with models (require creativity)
Example: Double Helix- model, not observed
Atom- not observed, models form invest.

8. C. Logic and reason
Scientific ideas do not emerge automatically or by number crunching
Imagine- invent new ways to explain how
Collect data, analyze data, and interpret results
Science= blend of logic, imagination, creativity

9. III. Misconception about the Method of Scientific Investigations
Scientists answer questions
Lit reviews, analyze existing data, observations in field or lab, develop models, design experiments
Steps of the scientific method do not capture all the ways scientists answer questions
Scientific Method
Not absolute- more of a way to write up results of studies
No single universal steps that scientists follow

10. D. Accidental Discoveries 1. the unexpected happen
C. Not always a question
Identifying causal relationships or eliminating possibilities
Different disciplines require different types of inquiry (different approaches)
D. Accidental Discoveries
1. the unexpected happen
2. Different than the classroom learning- not outcome driven
