Independent & Dependent Variables
I have found my students have a great deal of difficulty with the concept of independent and dependent variables. Newer textbooks will now call these variables “manipulated and responding” but that still doesn’t seem to make it easier for students to identify which is which. No matter how many examples I give them, how many labs, how many graphs, my students will get these questions wrong, particularly on multiple choice tests where there are choices meant to distract the student. This worksheet was designed as a way to get students to quickly read and identify the variables in a scenario. Each scenario is only a couple sentence long, such as ” One grape is placed in tap water and another grape is placed in salt water. The change in their mass is measured after a day. ” In the chart, students would identify the independent variable as the type of water and the dependent variable as the mass of the grapes. The worksheet is made very simple, to be practice just about those variables and not other aspects of the scientific method. For differentiation, I also have a Bee version (low level) of the worksheet that gives multiple choice options. This version may also be useful for test preparation with other groups. Grade Level: 8-10 Download PDF Google Doc Key (TpT) What is the independent variable answer key?Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
How did you identify the independent variable and dependent variable?An easy way to think of independent and dependent variables is, when you're conducting an experiment, the independent variable is what you change, and the dependent variable is what changes because of that. You can also think of the independent variable as the cause and the dependent variable as the effect.
What is the independent variable worksheet?An independent variable is the one thing you intend to vary in an experiment. A dependent variable is the thing that will change that you intend to measure as a quantitative assessment of the effect. 3.
What are some examples of independent dependent and controlled variables?Example: a car going down different surfaces. Independent variable: the surface of the slope rug, bubble wrap and wood. Dependent variable: the time it takes for the car to go down the slope. Controlled variable: the height of the slope, the car, the unit of time e.g. minutes and the length of the slope.
