Below are sample questions representative of the exercises included on this worksheet and related 4.66 Variables, Controls and Fair Tests skill assessments:

Problem 1Difficulty: Mastery

Data plan for a pulley investigation: test different values of load mass, keep the pulley setup the same, and record force needed to lift the load for each trial. Which statement correctly describes the variables?

Aforce needed to lift the load is the independent variable because it is measured after the test

Bthe pulley setup should change in every trial to make the test fair

CThe variables do not matter if the class writes down numbers

Dload mass is the independent variable, force needed to lift the load is the dependent variable, and the pulley setup is the controlled variable

Solution & Explanation:The independent variable is changed on purpose, the dependent variable is measured, and the controlled variable(s) are kept the same so the comparison is fair.

Problem 2Difficulty: Mastery

Data plan for a windmill model investigation: test different values of blade shape, keep the fan speed the same, and record number of turns for each trial. Which statement correctly describes the variables?

Anumber of turns is the independent variable because it is measured after the test

Bthe fan speed should change in every trial to make the test fair

Cblade shape is the independent variable, number of turns is the dependent variable, and the fan speed is the controlled variable

DThe variables do not matter if the class writes down numbers

Solution & Explanation:The independent variable is changed on purpose, the dependent variable is measured, and the controlled variable(s) are kept the same so the comparison is fair.

Problem 3Difficulty: Mastery

Data plan for a soil erosion tray investigation: test different values of plant cover, keep the slope and water amount the same, and record soil lost for each trial. Which statement correctly describes the variables?

Asoil lost is the independent variable because it is measured after the test

Bplant cover is the independent variable, soil lost is the dependent variable, and the slope and water amount are the controlled variables

Cthe slope and water amount should change in every trial to make the test fair

DThe variables do not matter if the class writes down numbers

Solution & Explanation:The independent variable is changed on purpose, the dependent variable is measured, and the controlled variable(s) are kept the same so the comparison is fair.
