1 The Scientific Method- also known as Inductivism 1. observation 2
The Scientific Method- also known as Inductivism 1. observation 2. hypothesis 3. experiment 4. law 5. theory

2 A good experiment will have the following: controllability, measurability and repeatability

3 A good scientific statement - must be clearly stated - does not have ad hoc exceptions

4 Problems with Observations: 1
Problems with Observations: 1. relevance- it is difficult to decide what is relevant and what is not 2. expectations- our expectations can influence what we see 3. expert seeing- scientific equipment has its shortcomings 4. the observer effect- the act of observation can affect the observation

5 Problems with Testing Hypothesis: 1
Problems with Testing Hypothesis: 1. confirmation bias- looking for answers that confirm your suspicions 2. background assumptions- unfounded assumptions based on the nature of things

6 Many different hypotheses are consistent with a given set of data
Many different hypotheses are consistent with a given set of data. How, then, do we select the correct hypothesis?

7 The scientific method is also known as Inductivism, which is based on induction. What is the problem with this?

8 Inductive reasoning goes from specific to general
Inductive reasoning goes from specific to general. From the observed to the unobserved. Therefore, we make a generalization about something.

9 The 3 most well known scientific paradigms:
Newtonian Mechanics (physics) Atomic Theory (chemistry) Evolutionary Theory (biology)
