|
Scientific Method
|
A process of doing science, using several steps.
|
|
|
Observation
|
Something you notice about your surroundings, that can detected by your senses.
|
|
|
Purpose
|
A question, something you want to figure out about the observation you made.
|
|
|
Hypothesis
|
A possible scientific answer, to a question, based on observation, prior knowledge and evidence, must be tested.
|
|
|
Experiment

Testing ones hypothesis by collecting and recording data, a data table is often used.
|
|
|
Analysis and Conclusion
|
Evaluating and interpreting your data to determine whether your hypothesis was correct, graphs are often used.
|
|
|
Repeat
|
Repeating an experiment to ensure you have the same consist results that are accurate.
|
|
|
Theory
|
Used to explain a wide set of of observed observations and facts, backed by large amounts of evidence.
|
|
|
Quantitative Observations
|
Involves taking measurements, such as temperature, mass, size, distance, velocity, etc.
|
|
|
Qualitative Observations
|
Involves describing the general properties of a materiel that may be used to identify it such as color, smell, feel, texture, etc.
|
|
|
Direct Observations

Observations from things seen.
|
|
|
Indirect Observations
|

|
|

|
|
|
Dependent Variable

|
|
|
Control Group
|
A group where the independent variable is not changed to provide a comparison.
|
|
|
Experimental Group
|
A group where the independent variable is changed and the results are compared with the control group.
|
|
|
