SPI 0807.Inq.1 Variables and Controls Review • What Are Control Experiments? • An experiment to verify the results of another experiment • using the same conditions except for one factor or variable • Simply remove the independent variable entirely or replace it with a neutral independent variable. • Example 02: • A student conducts an experiment to determine which type of • ballpoint writing pen will last the longest before running out of ink. • Experimental Group • Uses 3 types of ink pens in a series of experiments • (Blue ink pen, Black ink pen, red ink pen) • He copies text from his science book. He copies the same text over • and over. He writes at the same speed. The room temperature • remains the same. He writes on the same kind of paper. • Control Group • Uses 3 types of non-ballpoint pens in a series of experiments • Uses the same constants as the experimental group
SPI 0807.Inq.1 Variables and Controls Notes • Experimental group • All the details of the series of experiments using the 3 • types of ballpoint pens • Control group • All the details of the 3 non-ballpoint pens NOTE: The non-ballpoint pens are the control variables!
