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. Then, she's going to take this information and put it into the experiment stage, and then she will come to her final conclusion!

Research studies utilizing twins have demonstrated that numerous attributes and disarranges are heritable. For instance, in indistinguishable twin sets, on the off chance that one twin is determined to have schizophrenia, there is a half shot that the other twin will likewise be analyzed. Be that as it may, in congenial twin matches, this rate is just 15%. Since indistinguishable twins share a larger number of qualities than brotherly twins, we can infer that schizophrenia has an acquired organic premise.
