Biology as a Science/Tools of a Biologist Flashcards
Why do we need the scientific method
It is a standard for scientific practices so we can be assured that everyone put in as much work as whats needed
Steps of the Scientific Method
- define the problem
- make a hypothesis
- test your hypothesis
- collect data
- analyze data and make a conclusion
- publish your experiment
Control Group
A standard set of data to compare your experiment to (ex. watering plants with water when experimenting with different liquids)
Positive Control Group
Something you know will already work better than standard
Experimental Group
The thing you are experimenting on
Negative Control
Something you know will work because it was always done that way but it doesn’t work as best as it could work
Variable
The thing that changes throughout the experiment
Independent Variable
The number varies but you control it
Dependant Variable
The number changes but nature controls it (your data)
Null Hypothesis
When no difference exists in the experimental group and the control group
Theory
An explanation for many different observations and explains may hypothesises but is not always true
Law
Something that it always true and has been seen over and over and over (law of gravity)
