Scientific Method Case Study: Resolving a Lawn Problem
The scenario for this case study is that you notice that the grass around my house is brown, short, and dead. The grass around my neighbor's house is green, tall, and alive. Utilizing my understanding of the Scientific Method, my intent is to explain what the problem is to develop a hypothesis. After developing the hypothesis I will then design and perform an experiment to test my hypothesis; analyze my data and reach conclusions regarding my hypothesis. I will

More water needs to be supplied at a constant flow. The sprinkler system at the home should be re-set to supply water to the lawn every three days. To measure the water applies to the lawn; place at least five straight-sided #303 cans in various locations, at least four feet from a sprinkler head. Water the lawn for fifteen minutes, and then measure the depth of the water in each can. Then find the average amount of water from the cans, and then match the sprinkler output with the water depth provided by the Weber County Extension Service water depth table. (4) The cans in your lawn averaged 1/8 of an inch. In the summer you must water the lawn for one hundred four minutes, every three days. If it rains, pretend that you just finished watering your lawn and continue to keep the same watering schedule. This will help to prevent over watering. Based on this experiment, my grass began to be green, tall, and alive. The hypothesis that my grass was running out of water was correct. It will be essential that I maintain this watering schedule to promote healthy lawn growth year round. You should always have the luxury of green, tall, and alive grass surrounding your home! For my second hypothesis, ideally I want loam—soil that has roughly equal amounts of silt, sand and clay. A perfect loam is about 40 percent silt, 40 % sand and only 20 percent clay. Loam is fairly loose, but it has enough clay to absorb water effectively. The
