1 Pick one & journal your thoughts about it
This week in science Pick one & journal your thoughts about it

2 Today Read misconception of your choice
Start drafting paper due next Friday Books Review serial dilutions HW: notes due wed 9/14 essay due fri 9/16

3 Misconception topics I
Misconception topics I. Misconception about the Nature of Scientific Knowledge II. Misconception about the Work of Scientists (Nature of Scientists) III. Misconception about the Method of Scientific Investigations 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
