Question 7

We are out taking a walk one day when we notice two large fields. One is all grass while the other a mix of grass and native wild flowers. We wonder if there is a difference in the number of different bird species each field has using it. We think that the field with the grass and wild flowers will have more different bird species using it than the field with just the grass alone. We set up an experiment where we census the birds in each field. We census each field once a week for three months. Censuses are done on both fields at the same time and using the same techniques. We find that a total of 6 different bird species using the grass field and 10 different species using the grass and wildflower field.

Answer 1

The correct answer will be-

Case I- option-B

Case-II-option-B

Step-by-step explanation:

A scientific method is the best procedural approach to explain the natural phenomenon. The method includes various steps which begin with the making the observation. The observation leads to the asking the scientific questions which could be answered by proposing a hypothesis.

The hypothesis must be tested through experiments which could prove and disprove the hypothesis and can answer the natural phenomenon.

Case-I

In the given situation of the question in which a person notices or observes the fields of grass and grass and native flower. Since the researcher notices the fields, they are performing the first step of the method that is "making an observation" and thus Option-B is the correct answer.

Case-II

In the situation, which discusses the number of birds in the fields shows the "dependent variables". The dependent variable is the parameter which is studied in the experiments. Since in the given conditions the number of birds is being studied, therefore, Option-B is the correct answer.
