To make a bigger splash in their next trial, the student should consider what factors contribute to the splash when a ball enters the water. Generally, a bigger splash can be created by:
1. Increasing the initial height from which the ball is dropped, which increases the speed of the ball at impact due to gravity.
2. Increasing the mass of the object, which can result in a greater force upon impact, thereby making a larger splash.
Considering the options provided:
a. Dropping from a lower height would decrease the speed and produce a smaller splash.
b. Dropping with less speed would also result in a smaller splash.
c. Using a ball with less mass would result in a smaller splash since it has less force upon impact.
d. Using a ball with more mass but the same diameter would increase the impact force and likely create a bigger splash.
Thus, the best option for them to achieve a bigger splash would be:
**d. they can use a ball with the same diameter but more mass.**
