Question

identify the variables for the following investigation in the graphic organizer: how do different batteries affect the energy in a cell phone? instructions table with columns variable (independent, dependent, control) and description

Explanation:

• Independent Variable: The factor that is manipulated. Here, the type of battery (different batteries) is what we change to see its effect.
• Dependent Variable: The factor that is measured/responds. The energy in the cell phone depends on the battery used, so it's the dependent variable.
• Control Variable: Factors kept constant to ensure a fair test. For example, the same cell phone model, same usage conditions (like same apps running, same screen brightness), etc., so that only the battery type affects the energy.

Answer:

Variable	Description
Dependent	The energy in the cell phone (measured as a result of using different batteries)
Control	Factors like cell phone model, usage conditions (e.g., apps, screen brightness) kept constant
