Characteristics of science
The goal is to expose facts in the purest way
Objetive
Characteristics of science
All actions and observations follow methods and rules
Controlled
Characteristics of science
Findings should be able to be reproduced
Verifiable
Characteristics of science
Scientific investigations must be able to be questioned and rectified
Provisional
Organized process that scientists use to solve investigation problems
Scientific method
Act of collecting info. and data to form questions
Observation
Probable answer to the question
Hypothesis
Conditions under which an experiment is given and that can change
Variable
Condition that will be measured or investigated
Dependent variable
Condition that will be changed or manipulated in the experiment
Independent variable
Conditions that will be held constant
Controlled variable
Information describing odor, shape, color, or other physical characteristics
Qualitative data
Answers the question of “how”?; measurable quantities and units
Quantitative data
Whether the hypothesis is true or false, justified by data.
Conclusion
Hypothesis supported by many experiments
