A student carries out an experiment. She clears an area of soil in her backyard. She keeps the soil watered and makes careful weekly observations of the area. She uses a notebook to record data about the plant growth in the area of study. Originally she observes only worm and insect activity in the soil. After 2 weeks she notices the growth of grass and weeds in the soil. She also notices an increase in insect activity in the area. She continues her observations over a period of three months.
