9. What is Science? The Goal of science is to investigate and understand the natural world, to explain events in the natural world. Observation: The process of gathering information about events or processes

10. What is Science? The Goal of science is to investigate and understand the natural world, to explain events in the natural world. Observation: The process of gathering information about events or processes

11. What is Science? Data: The information gathered from observation

12. What is Science? Data: The information gathered from observation Hypothesis: An educated guess or prediction, based upon the observations

13. What is Science? Data: The information gathered from observation Hypothesis: An educated guess or prediction, based upon the observations When testing an experiment, only one variable is changed and tested at a time. Variable: Anything that can change in an experiment

14. What is Science? Independent Variable: The variable in an experiment that is changed and manipulated, the input (Flipping the light switch)

15. What is Science? Independent Variable: The variable in an experiment that is changed and manipulated, the input (Flipping the light switch) Dependent Variable: The variable in an experiment that is being measured, the output (light turns on)

16. What is Science? Independent Variable: The variable in an experiment that is changed and manipulated, the input (Flipping the light switch) Dependent Variable: The variable in an experiment that is being measured, the output (light turns on) Control Variable: The variable that the experiment is being compared to, the standard. (Not flipping the light switch)

(Not flipping the light switch) Theory: A well tested explanation with consistent results (Not a fact!)
