The principal, Mrs. Integer tells Mrs. Apex to write down exactly what she is doing step by step. In the scientific method this is called ... a the conclusion. b the data. c the hypothesis d the observation e the procedure

E. the procedure

Explanation:

In scientific experiments, several steps are taken in order to achieve a significant result. However, the steps involved when performing the experiment should be taken note of and written down in a very comprehensible manner. The written step by step process involved in an experiment is called the PROCEDURE.

A procedure should be a guide to performing the experiment by a new experimenter. It should include everything done during the experiment. In this case, Mrs. Integer is telling Mrs. Apex to write down all she is doing during the experiment in a step by step manner. In essence, the principal is simply asking her to write a PROCEDURE.
