a student is experimenting with dissolving sugar in water. he can measure the volume of water in the beaker, the number of spoons of sugar added, the time that it takes for the sugar to dissolve, and the temperature of the water in the beaker. if he wants to investigate how the time taken for the sugar to dissolve is affected by the volume of water in the beaker, what independent, dependent, and control variables should he use? independent variable: dependent variable: control variables:

Answer

Brief Explanations:

The independent variable is what is changed in an experiment. Here, it's the volume of water as it's being manipulated to see its effect. The dependent variable is what is measured as a result of the change in the independent variable, which is the time taken for sugar to dissolve. Control variables are kept constant to ensure only the independent variable affects the dependent variable. So, the number of spoons of sugar and water temperature should be controlled.

Answer:

Independent Variable: Volume of water in the beaker Dependent Variable: Time taken for the sugar to dissolve Control Variables: Number of spoons of sugar, temperature of the water in the beaker
