In this experiment, you will determine which of four variables affect the breakdown of rock samples. to do that, you will change one variable at a time and then measure the change in mass of the rock sample. in the space below, write a scientific question you will answer by doing this experiment.

The question could be: After testing all the four variables and comparing all the changes in mass. Which of the four variables affect the breakdown of the rock sample?

Explanation:

Both the variables and the change in mass are essential information to answer the question; for that reason, it is necessary to include it before the actual question.
