To make a bigger splash, the students should consider the factors that affect kinetic energy, which is dependent on both mass and velocity. The best option given the choices is:
They can use a ball with the same diameter but more mass.
Using a ball with more mass will increase the kinetic energy when it hits the water, resulting in a bigger splash.
