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
Nature of Science NotesNature of Science Notes
• AIM/GOAL OF SCIENCE
• LIMITATION
• To understand the world around us
• Limited to the natural (A.K.A. material) world

• AIM/GOAL OF SCIENCE
• LIMITATION
• CRITICAL THINKING
• To understand the world around us
• Limited to the real (material) world
• Science and CT go hand-in-hand
Nature of Science NotesNature of Science Notes
• 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”
Nature of Science NotesNature of Science Notes
• 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.

• 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?
Nature of Science NotesNature of Science Notes
• 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
