Question

piece. then he chewed each piece for 10 minutes. after that, he let the gum dry and weighed it again. he recorded his data in the table below. what is the independent variable in kules experiment? the brand of gum the weight of the final dried gum the time chewed the change in weight of the gum

Explanation:

In an experiment, the independent variable is the factor that is deliberately changed or manipulated by the experimenter. Here, Kule is likely testing different brands of gum (as that's what would vary between different trials). The time chewed is kept constant (10 minutes), so it's not the independent variable. The weight of the final dried gum and the change in weight of the gum are dependent variables (they depend on what happens during the chewing, which might relate to the brand).

Answer:

the brand of gum
