What is an example of a variable in science?
Example: In the experiment measuring the effect of temperature on solubility, controlled variable could include the source of water used in the experiment, the size and type of containers used to mix chemicals, and the amount of mixing time allowed for each solution.
What are the 3 variables in science?
There are three main variables: independent variable, dependent variable and controlled variables. Example: a car going down different surfaces.
What are the 3 variables in an experiment?
Define the Variables. There should be three categories of variables in every experiment: dependent, independent, and controlled. Dependent — is what will be measured; it’s what the investigator thinks will be affected during the experiment. For example, the investigator may want to study coffee bean growth.
What are variables in a project topic?
All research projects are based around variables. A variable is the characteristic or attribute of an individual, group, educational system, or the environment that is of interest in a research study. Variables can be straightforward and easy to measure, such as gender, age, or course of study.
What is an independent variable in science examples?
It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable. Other factors (such as what they eat, how much they go to school, how much television they watch) aren’t going to change a person’s age.
What is variable and its type?

How do you explain independent variables?
An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable.
