A well-written research question states the independent and dependent variables in the experiment.
For example, a student investigated the effect of soil pH on the number of strawberries produced by a
strawberry plant. Her research question was "How does the pH of soil affect the number of strawberriesproduced by a strawberry plant?

10. Write a research question, using the format suggested in the Read This! box, for the experiment inModel 2.

11. A student wonders, "Does the moisture content in soil affect how far a worm can dig?" Identify the variables that are being considered in this experiment and the variables that need to be
controlled.

The variables in the experiment being considered are :

  • Independent variable = moisture content
  • Dependent variable = Depth
  • Control variable = soil type

For the first question, the model 2 experiment isn't given. However, to buttress on the stating both the dependent and independent variables in a research question ;

Taking the example given as an instance ;

The Independent variable is Soil pH : The Independent variables are used causes changes to the dependent variable. In this case, the dependent variable is the number of strawberries produced. The Different soil pH level are used to observe the changes in the Number of strawberries produced by the strawberry plant.

2.)

  • The Independent variable is the variable being manipulated by the researcher in other to observe the behavior of the dependent variable. In the experiment stated, the independent variables is the moisture content.

  • The dependent variable is the variable being measured as the experimenter manipulates the independent variable, in this context, the dependent variable is depth being dug by the worm.

  • The control variables are variables which are capable of influencing the result or outcome of our experiment but which we do not wish to test at the moment. A very important control variable in this context is the soil type.
