Question

collect data • use the turbine town digital interactive to collect data in response to your first investigation question. fill in the columns in the data table for each of the variables. part 1: how does the force of the water affect the motion of the turbine? independent variable dependent variable control variable which variable are you going to change to answer your second investigation question?

Explanation:

Step1: Identify independent variable

The independent variable is what is changed. Here, it is the force of the water as we are testing its effect on the turbine.

Step2: Identify dependent variable

The dependent variable is what is measured and is affected by the independent variable. So, it is the motion of the turbine.

Step3: Identify control variables

Control variables are kept constant. Examples could be the type of turbine, its size, the temperature of the water, etc.

Answer:

Independent Variable: Force of the water
Dependent Variable: Motion of the turbine
Control Variable: Type of turbine, size of turbine, water - temperature (and other factors that could affect the turbine's motion but are not being tested)
