1. Intro. To Science

2. An Introduction to the Nature of Science
Perception & Bias
An Introduction to the
Nature of Science

3. Tenets of Scientific Knowledge Is…
Empirically based (facts found by experimentation)
Tentative (subject to change)
The product of observation and inference
The product of creative thinking
Tenent:
1. A foundational truth
2. Something that is at the core of a topic
Edward Jenner

4. Ways of Knowing/Thinking
Paradigm
A conceptual way of thinking
The “lens” you look through to approach problems.
Defined as: “the way you see the world due to the experiences you have had in the past”

5. Perception/Paradigm
Our interpretations of scientific data are influenced by our background, or our perceptual framework.
Bias – a prejudice that can cause you to view the world a particular way
Look at the following pictures. What do you see?

8. Science is Tentative Tentative – subject to change
New evidence may force us change our understanding of the world
Scientific knowledge is never set in stone

9. Observations & Inferences

10. Observations & Inferences
Observation – information you’re able to gather using your five senses
Inference – conclusions you draw using your mind when you make an observation. “Connecting the dots”

13. Law vs. Theory
LAW
In science, a law is an explanation of events that always occur when given certain conditions (ex. Newtons law of gravity)
Tends to be specific
Can be expressed as a mathematical formula
Concise (short)
Can change!!!

14. Law vs. Theory
Theory
In science, an explanation of a lot of observations. A well supported hypothesis.
More general
Pulls multiple ideas or diverse data together
Offers explanation
Does not become a law
Can change, just like a law

15. So What?
Most people think a law is “better” or “more proven” than a theory…
WRONG!!!
The only fundamental difference between scientific law and theory is
Laws a shorter statements that can often be mathematical, while…
Theories are longer statements that bring many ideas together (usually no math)
