To provide explanations for events in the natural world

It cures diseases, places satellites, and send instantaneous electronic communications.
Involves observing and asking questions, making inferences and forming hypotheses, conducting controlled experiments, collecting and analyzing data, and drawing conclusions
The Scientific Method
The act of noticing and describing events or processes in a careful, orderly way.
Observation
A logical interpretation based on what scientists already know
Inference
A scientific explanation for a set of observations that can be tested in ways that support or reject it
Hypothesis
After making a hypothesis, you test to see if it is true with multiple variables. Only one variable should change and all the others are controlled
A controlled experiment
Why is it important to be able to control variables in a controlled experiment?
It’s important because if many variables change, scientists won’t know which one led to the result of the controlled experiment.
The variable that is deliberately changed. What you control
Independent variable
The variable that is observed and that changes in response to the independent variable. The result
Dependent variable
