Answer 1

Answer:

According to the information, the independentvariable is the size of the ball used for the experiment, the dependentvariable is the time the ball lasts in the air.

What is an experiment?

An experiment is a term used in science to refer to one or more procedures that allow the individual to prove or deny a phenomenon.

What are the variables in this experiment?

The variables of this experiment are the sizes of the balls (independent variable) and the time the ball lasts in the airjuggling (dependent variable).

According to the above, the independentvariable is the size of the ball because this is the one that will modify the other variable, that is, the time that the ball remains in the air. Additionally, with this experiment a hypothesis can be established about the relationship between the size of the ball and juggling.

On the other hand, this test should be performed severaltimes to identify a trend on juggling each ball to establish an averagetime. For example:

With ball #3, 5 tests are made and the average time is 20 seconds.
With ball #4, 5 tests are made and the average time is 10 seconds.
With the #5 ball, 5 tests are made and the average time is 5 seconds.

This means that the bigger the ball, the more difficult it is to juggle it.
