Question

the passage below describes an experiment. leo works at a candy store and makes rock candy. his customers preferred rock candy with larger sugar crystals, so he wanted to know how he could get the largest crystals. he wondered if using a different type of sugar would result in a different size of sugar crystals. leo set up 12 glass jars with a stick and hot water. he added granulated sugar to four jars, brown sugar to another four jars, and pure cane sugar to the remaining four jars. after one week, leo removed the rock candy from each jar and measured the size of the sugar crystals. complete the sentence. in this experiment, the type of sugar used was an independent variable a dependent variable

Explanation:

The independent variable is the factor that the experimenter manipulates or changes. Here, Leo changes the type of sugar (granulated, brown, pure cane sugar) to see its effect on the size of sugar - crystals. The size of the sugar - crystals is the dependent variable that is expected to change based on the type of sugar used.

Answer:

an independent variable
