Name:______KEY___________Date:_________ Identify the Independent (IV) and Dependent (DV) Variable of Each Scenario. Justin wants to determine the effect of fertilizer on the growth of grass.

After 3 days he notices his nails on his left hand have grown but he continued to bite his right hand nails. Independent Variable = Bitter tasting nail polish on left hand Dependent Variable = Length of fingernails Control = Right hand with no polish If you are satisfied with this worksheet, please leave positive feedback! Thanks,

IV: DV: Hypothesis: 3. In what grade level do students grow the quickest? IV: DV: Hypothesis: 4. Is riding the bus or riding a bike a quicker way to get to school? IV: DV: Hypothesis: life? IV: DV: Hypothesis: 10. Does grass grow faster under the shade of a tree or in the direct sunlight? IV: DV: Hypothesis: Hypothesis and Variables Worksheet ...

Directions: For the following problems, the factors from the experiment are listed. Label whether each factor is a constant (CST), a control (CTL), an independent variable (IV), or a dependent variable (DV). Example 1 Mr. Kron decides to market and sell a candy bar called the “Baby Kron” at the Spartan Mart.

IV = independent variable DV = dependent variable LT: I can define independent variable (IV), dependent variable (DV), and constant and identify each in an experiment. ____ Identify the types of variables in each written statement. READ CAREFULLY! A study was done to find if fuel types affect the engine’s performance in a car.

A dependent variable is the thing that will change that you intend to measure as a quantitative assessment of the effect. In the following examples identify the independent and dependent variables and then also list several potential confounding variables that the experimenters would have to consider.

Use each description and/or data table to help you identify or describe: 1) any independent variable(s), 2) the best dependent variable, 3) at least 3 variables that should be controlled or held constant, and 4) any control group(s) in the experiment. Make sure your answers are specific. Keep in mind that not all experiments have a control group.

Independent and Dependent Variables: ANSWERS Time on Social MediaLess books read

Practice identifying independent and dependent variables in science experiments. Includes definitions and examples for middle school students.

There can be several controlled variables. If an experiment is to be useful, only one variable at a time can be manipulated intentionally. All other variables must be controlled throughout all parts of the experiment. If more than one variable is altered (changed), the results of an experiment cannot be interpreted with any validity.

For each of the following problem statements, identify the IV, DV, and constants. Then write a hypothesis. Remember the following format: If...(IV goes here), Then...(DV goes here), Because...

Test yourself (extension): Complete the Identify the IV and DV worksheet. Come up with your own hypothesis and clearly state the operationalised IV and DV. Create a video or audio clip of yourself presenting on the role of IV's and DV's in a hypothesis, and the need to operationalise.

In each of the examples, identify the independent variable and dependent variable as well as which participants make up the experimental group and which make up the control group.

For each of the problem statements listed below, identify the independent (IV) and dependent (DV) variable, and determine whether each variable is qualitative or quantitative. Answers follow the problem statements.

Practice: Remember -the key to a good research question is that it can be tested. If the question is based on opinions or personal preferences, then it is not testable.

3. James wants to know the effect of studying an extra 10 minutes each day on his Biology grade.

Then they were given the problem solving test. IV: Hours slept DV: Test scores A recent report found that blueberries enhanced the maze running performance of mice. What was the independent variable and dependent variable of this experiment? IV: Number of blueberries given DV: Time taken to finish maze.
