Students want to design an experiment to study gravity. They decide they will drop four objects with the same mass from the top of their school’s bleachers. They will time how long each object takes to reach the ground. How can they improve confidence in the experiment’s results?(1 point)

Let a different student time the drop of each object.

Drop each object 10 times and use the average of each object’s fall times.

Randomly select the order in which the objects are dropped.

Drop all four objects at once.

- Let a different student time the drop of each object to reduce any bias or errors in timing.

- Drop each object 10 times and use the average of each object’s fall times to account for any variations in individual trials.
- Randomly select the order in which the objects are dropped to avoid any potential confounding variables.
- Dropping all four objects at once may not provide accurate individual fall times, so it is best to drop them separately.
