A student conducts an experiment to determine how the temperature of water affects the time for sugar to dissolve. In each trial, the student uses a different amount of sugar and a different temperature of water. What is wrong with this experimental design? The student changed too many variables. The student needs to perform more trials. The student does not have a dependent variable. The student did not change enough variables.

What three things determine the shape and size of a puddle when water is poured out onto a surface
