In this lab, students will test two different soil samples, one from a natural environment and the other from a location impacted by humans, for their water-holding capacity, organic matter content, pH level, and nutrient content (nitrogen, phosphorus, and potassium).
At the end of this investigation, students will be able to determine that soil from a natural environment is ideal for plant growth as it is able to hold more water, has more organic matter, and has optimal pH and nutrient levels.
