|
data
|
recorded observations or items of information
|
|
generalization
|
general conclusion based on many specific observations
|
|
hypothesis

suggested, testable answer to a well-defined scientific question
|
|
quantitative data
|
observations recorded as measurements
|
|
qualitative data
|
the form of descriptions (e.g. pictures) instead of measurements

evidence
|
a collected body of data form observation and experiments
evidence must be reliable=> observations and experiments must have been observed multiple times |
|
hypothesis
|
a scientific hypothesis must be falsifiable there must be an experiments that goes wrong

|
limitations in science
|
science cannot answer every question
science cannot prove or disprove supernatural forces science isn't the only way of knowing things |

theories can be modified or discarded if new evidence is uncovered |
|
model

physical mental or mathematical representation of how people understand a process or idea
e.g. drawings graphs maps |
|
communication in science
|
most scientists work n teams
researchers share their findings by publishing results |
