Lilly created an experiment to test if she could make water in a glass move when she

played music with her trumpet. She set a glass of water on the table and organized four trials in which the length of "time she played was the same (10 seconds), but the distance between her and the glass of water was different.

In the data table shown below, she recorded her observations of ripples in the water.

Based on the evidence in the table which of the four trials caused a change in the water?

• Trial 1

• Trial 2

• Trial 3

• Trial 4
