Hemlocks are a common type of tree in the northern forests of the United States. In studying one forest, a forester noticed that
mature hemlocks were abundant but there were very few young hemlocks. She wondered why there were so few young hemlocks. By reading the records that other foresters in that area had kept, she learned that the population of deer living in the forest had doubled in the last five years. By reading studies on forests that other scientists had performed, she also learned that deer in similar forests like to eat young hemlocks and the young trees of other species. In the scenario, the forester wonders why one forest had many mature hemlocks but very few young hemlocks. Which part of a scientific method does this best illustrate? A. forming a hypothesisB. making an observation and asking a questionC. communicating the results of a studyD. setting up an experiment
In scientific method there need to be a situation to be study. In this description, the scientist first observed that in a certain region there is some kind of trees and the other variable is the great amount of deer.
After making different observations, and some research of other areas similar to the one that is study, she is asking what is the relation among the animals and the trees.
The next step will be to formulate a hypothesis using all the data and the two variables that she observed.
