Omar wrote a hypothesis about batteries called dry cells.
If more dry cells are connected end to end, a light bulb will work longer because there is more energy available.
What are the variables in his hypothesis?
The independent variable is the number of dry cells, and the dependent variable is the length of time the bulb works.
