The step of the scientific method that involves identifying variables is typically the "Formulating a Hypothesis" stage. During this phase, researchers define the independent and dependent variables that will be tested in their experiments. Clearly identifying these variables is crucial for designing the experiment and determining how changes in one variable may affect another. This step sets the foundation for a structured investigation and analysis.
The first step of the scientific method requires scientists to observe in order to obtain information. The next step is to formulate a hypothesis.
As many as are necessary, as few as possible.

You establish a controlled variable from which you can compare your results from your experimental variables.

They're the parameters that vary. Hence the name.

A controlled investigation is an experiment where one variable is manipulated (independent variable) to observe its effect on another variable (dependent variable), while controlling for and monitoring other variables to ensure they do not influence the results. This helps to establish causal relationships between variables and reduce the impact of confounding factors on the results.

The variables that are kept the same in an investigation are called "controlled variables" or "constants." These variables are maintained at the same level to ensure that any observed changes in the dependent variable can be attributed solely to the manipulation of the independent variable. By controlling these variables, researchers can enhance the reliability and validity of their experimental results.
Variables are the different thing in the experiment. Ex.-Problem-Which ball rolls fastest? Hypothesis-The Softball will roll fastest. Investigation-Roll the balls at the same time and time them with a stopwatch. Conclusion-Basketball rolled the fastest. Variables-The balls.
A hidden variable in a scientific context typically refers to an unknown factor that may influence the outcome of a study or experiment but is not being measured or accounted for. Identifying and controlling for hidden variables is important to ensure the validity and reliability of research findings.
Variables in the scientific method are elements that can be changed or controlled in an experiment to test their effects on other variables. They are typically classified into three types: independent variables, which are manipulated by the researcher; dependent variables, which are measured in response to changes in the independent variable; and controlled variables, which are kept constant to ensure that the results are due to the manipulation of the independent variable. Properly identifying and managing these variables is crucial for obtaining valid and reliable results in scientific research.
a descriptive investigation is a scientific ivestigation that collects data which measure or decribe objects or events. it collects qualitative & quantitative data. it includes a question, but no hypothesis ; no variables are manipulated .
