Answer:
This question is incomplete; the complete question is:
Beatrice, a middle school student, is visiting a very tall office building and notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is travelling down. After making these observations, Beatrice comes back to the building and stands on a bathroom scale that measures her weight as she travels up and down in the elevator. What is one variable Beatrice could change in her investigation? What might she figure out if this variable were changed?
ANSWERS:
- Beatrice could change the independent variable, which is the direction of the elevator's movement
- Beatrice might figure out how her WEIGHT responds if she changes the direction of the elevator's movement
Explanation:
According to this experiment, Beatrice notices that she feels heavier when the elevator car is traveling up and lighter when the elevator car is travelling down. She decides to test this observation by conducting an experiment where she measures her weight as she travels up and down in the elevator.
In any scientific experiment, the variable that an experimenter can change is called the INDEPENDENT VARIABLE, which in this case is the DIRECTION OF THE ELEVATOR. Beatrice could change whether the elevator will go down or up.
Also, another variable called the DEPENDENT VARIABLE is the variable that responds to the changes made to the independent variable in an experiment. In this case, if Beatrice changes the direction of the elevator's movement, she might figure out her WEIGHT RESPONSE to the direction of elevator movement.
