THE NATURE OF THE NATURE OF SCIENCESCIENCE

THE NATURE OF SCIENCETHE NATURE OF SCIENCE

• MAIN IDEAS • SUPPORTING DETAILS

Nature of Science NotesNature of Science Notes

• AIM/GOAL OF SCIENCE

• To understand the world around us



• LIMITATION


• Limited to the natural (A.K.A. material) world



• LIMITATION

• CRITICAL THINKING


• Limited to the real (material) world

• Science and CT go hand-in-hand


• ASSUMPTIONS 1. The world is real2. We can know about

the world3. Uniformity

• Things are the same everywhere

• e.x. Gravity

4. Natural/Natural• “willy and ethel

Nature of ScienceNature of Science

• Critical Thinking • Does NOT take things for granted

• Does NOT rely on authority

• Individual consideration• Duh!

– Truth is not obvious

• Uncertainty = Reality• INDIVIDUAL DECISION-

MAKING!

REALLY…REALLY…

SCIENCE + CRITICAL THINKING = TRUE LOVE!

NATURE OF SCIENCENATURE OF SCIENCE

• Science and Society

• It is a two-way street!– SCIENCE influences society– SOCIETY influences science soooo….– SCIENCE SOCIETY

• Examples:– Abortion– Stem Cell Research– Global Warming

A TIMELY COMPARISON!A TIMELY COMPARISON!

• BUSH ADMIN– "We do not know how

much effect natural fluctuations may have had on warming.“

– Banned certain types of abortion methods within the limits of Roe vs. Wade

– Banned stem cell research with embryos

• OBAMA ADMIN– “Global warming is

real, is happening now and is the result of human activities.”

– Will uphold Roe vs. Wade; wants states to legislate abortion rights

– Wants to lift ban on embryonic stem cell research

QUICK THOUGHTSQUICK THOUGHTS

• Based on your experience with the checks activity, define the word hypothesis WITHOUT using “guess”, “educated”, or “theory”


• Types of Scientific Knowledge

Hypothesis:– Statement based on

evidence hasn’t been proved true or false yet

– Prediction used in expt. Based on evidence; assume what will or has happened

– Estimation thought out about info given

– Statement that predicts the outcome of a sitiiation

– Decribe thoughts based on obser & infer.

Nature of ScienceNature of Science

• Characteristics of Scientific Knowledge

• Uncertain– Use word “confidence”

instead of certain

• Contingent• Evidence NOT proof!

– Evidence = OBSERVATIONS & INFERENCES!

• Modifiable – can change conclusions

based on new knowledge– new observations and

inferences

QUICK THOUGHTQUICK THOUGHT

• How did the Checks Activity demonstrate the characteristics of scientific knowledge that we just talked about?


• Types of Scientific Knowledge

Hypothesis:• Testable statement • based on observation

Theory:• EXPLANATION of a set

of observations• LOTS of data!• Has been repeatedly

confirmed!

Fact:• Agreed-upon observation• Ex. 206 bones in human

body• Can change, too!

REFLECTIONREFLECTION

• Write about– 3 NEW insights about science that you have

gained so far this year– 2 things that are similar to what you have

learned in past science classes– 1 question you still have about the Nature of

Science
