Curated OER
Experimental Research
In this experiment worksheet, students give examples of independent, dependent, and controlled variables. This worksheet is a graphic organizer.
Curated OER
Variables
Students watch a video show how to identify the independent variable, dependent variable and controls in an experiment; and design experiments that use controls to isolate a single independent variable and measure the resulting dependent...
