Donna has observed that her father can control the speed of their grandfather clock by adjusting the height of the weight on the end of the pendulum. Donna thinks that the pendulum will move

faster when the weight is lowered, and wants to test her idea. Donna gets a stopwatch and

measures the time it takes for the pendulum to swing twenty times when the weight is moved to

its lowest position. Donna begins to move the pendulum up by 1 cm and continues to measure

the time for twenty swings of the pendulum. Donna records her data.

What is would the hypothesis be, Independent/dependent variable, the constants and the control group of this experiment?

Thanks!
