 Show Name________________________________Date_________ Independent and Dependent Variables Scenarios (Manipulated) (Responding) www.biologycorner.com 1. A cow is given a growth hormone and then compared to another cow that was not given a growth hormone. Both cows were weighed at 2 years. 2. Mosquito repellent is sprayed on one arm and the other arm is not sprayed. The number of mosquito bites is counted after 2 hours. 3. 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. 4. Two different cars are traveling at 60 mph. At a certain point, both cars slam on the brakes. The distance it takes for each car to stop is then measured. 5. Pillbugs are placed in a container where they have a choice of a wet or a dry environment. Researchers record how much time was spent on each side. 6. A stapler is used to staple 100 papers, it jams 5 times during the trial. A different brand of stapler performs the same test; it jams 22 times. 7. Cockroaches are exposed to a pesticide. After 3 hours, 95% of the insects are dead. if the arm was sprayed with repellent or not time it took for the car to stop Amount of dead cockroaches What are some examples of independent and dependent variables?The type of soda – diet or regular – is the independent variable. The level of blood sugar that you measure is the dependent variable – it changes depending on the type of soda.
What are some examples of dependent and independent variables in the real world?In a study to determine whether how long a student sleeps affects test scores, the independent variable is the length of time spent sleeping while the dependent variable is the test score. You want to know which brand of fertilizer is best for your plants. The brand of fertilizer is the independent variable.
What are some examples of independent and dependent variables and control?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.
How do you identify independent and dependent variables?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.
