Explanation:

Q1

The scientific method starts with making observations to identify a problem or phenomenon. Experimentation (A) is later, forming a hypothesis (B) comes after observations, and analyzing data (C) is post - experiment. So the first step is making observations.

A hypothesis is a testable (A) explanation for an observation (C) and can be in an if/then statement (D). It does not restate the question; it proposes an explanation. So the statement that is not true is that it must restate the question.

An independent variable is the one that the experimenter intentionally manipulates. The variable being observed (B) is the dependent variable. The variable not changed (C) is a controlled variable. A variable dependent on the dependent variable (D) is incorrect. So the independent variable is intentionally manipulated.

Answer:

D. Making observations
