So, there's five steps to the scientific method: Identifying the problem, forming a hypothesis, doing research and collecting background data, conducting the experiment, and finally coming to a conclusion. Arya already completed step one and two, because she sees a problem (the dry soil), and then comes up with a hypothesis, which is the water content in the soil in her yard is 2/3 lower due to the slope of her yard. Next, she's going to have to go and collect her data! This may include taking soil samples from her own yard and her other neighbors yard, and then measuring the slope of their yards ect.
