What type of scientific investigation involves identifying and controlling variables?
laboratory experiment
What is the function of a control in a scientific investigation?
You establish a controlled variable from which you can compare your results from your experimental variables.
What should be done when designing a controlled experiment scientific investigation?
1.) List the needed materials. 2.) Plan the variables. 3.) List the procedures.
What are three kinds of variables used in scientific investigation?
In scientific investigations, three key types of variables are independent variables, dependent variables, and controlled variables. The independent variable is the factor that is manipulated or changed by the researcher to observe its effect. The dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Controlled variables are those that are kept constant throughout the experiment to ensure that any observed changes can be attributed solely to the independent variable.
What are the variables in the scientific investigation?
They're the parameters that vary. Hence the name.

What is descriptive investigation?
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 .

1.) List the needed materials. 2.) Plan the variables. 3.) List the procedures.
What is the best number of variables for a scientific investigation?
In an experiment containing a number of possible variables only one of these should be altered in each individual experiment. Otherwise it is not possible to determine which variable is responsible for a particular change.
What are the three variables that play an important role in a Practical Investigation?
Independent Variables, Dependent Variables and Extraneous Variables.

What is something that is part of a scientific investigation that can be controlled or measured?
One example of something that can be controlled in a scientific investigation is the environment in which an experiment takes place. This can include factors like temperature, humidity, or lighting. Measurement variables could include things like time, distance, volume, or weight.
What step of the scientific method involves identifying variables?
The first step of the scientific method requires scientists to observe in order to obtain information. The next step is to formulate a hypothesis.
Characteristics of scientific investigation?
A scientific investigation is a method of identifying a question through observations. Next, a hypothesis is formed as a tentative explanation for the question. Third, experiments are performed to test the hypothesis. Finally, a scientific paper is written to explain the conclusions.
