Presentation transcript:

The things that you keep the same in ALL trials of the experiment CONSTANTS : The things that you keep the same in ALL trials of the experiment Ex – Ramp height in speed lab CONTROL SET-UP: Trial(s) in the experiment that does not contain the thing you are testing (independent variable) EXPERIMENTAL SET-UP Trial(s) in the experiment that contains the independent variable (the thing that you are testing)

Factor that can change in response to independent variable Factor that is intentionally changed Variable being tested in your experiment Dependent Variable: Factor that can change in response to independent variable The result of the experiment what you measure or observe in the experiment and what can be affected during the experiment (Hint: Independent variable can possibly cause change in the dependent variable)

Is the classroom louder when the teacher leaves the room? Name : 1. Control 2. Constants 3. Independent Variable 4. Dependent Variable

CONTROL - when teacher is in the room. CONSTANTS Same classroom, same teacher, Same time of day

Independent Variable? Teacher location Dependent Variable? Loudness (measured in decibels)
