Question

Scenario Independent Variable Dependent Variable 1. One cow is fed a growth hormone and another cow is not. After a year, both cows are weighed. 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. Bob studies for a test and Jackie does not study. After the test, they compare their scores. 4. Two cars are on a track and accelerate to 60 km/h. At a certain point, both cars slam on the brakes. The distance it takes for each car to stop is then measured. 5. A group of people take a diet pill. After 3 months, they measure the amount of weight they lost. 6. Ants are placed in a tray that is shaped like a T, at the end of the T, the ants can either go to a darkened area or a light area. Students count how many ants end up on the dark side and how many end up on the light side. 7. One company states that it makes the best staplers. To prove it, they use the stapler to staple a thousand papers and compare it to a competitor. The competitor’s stapler jammed 3 times whereas their stapler only jammed once. 8. A doctor designs baby formula to help babies gain weight. To show his formula works, he compares the weights of babies that have been using the formula to the weights of babies not on the formula. 9. Cockroaches are exposed to the chemical dioxin. After 3 hours, 45/100 cockroaches are dead. 10. New houses are spayed on the outside with an insulating paint. After a year, researchers determine how much energy each house used.

Answer 1

1. Independent is the hormone, dependent is the weight.

2. Independent is the repellent, dependent is the mosquito bites.

3. Independent is studying, dependent is the score.

4. Independent is slamming the breaks, dependent is the distance.

5. Independent is the pill, dependent is the weight.

6. Independent is putting them in the tray, dependent is the side the go to.

7. Independent is the stapler, dependent is the times it got jammed.

8. Independent is the formula, dependent is the weight.

9. Independent is the chemical, dependent is the amount of dead cockroaches.

10. Independent is the paint, dependent is the energy used.

Hope this helps!!! :)

Answer 2

Answer:

1. The independent variable is the growth hormone, and the dependent variable is the weight.

2. The independent variable is the mosquito repellent, and the dependent variable is the number of mosquito bites.

3. The independent variable is if they studied, and the dependent variable is their scores.

4. The independent variable is the car, and the dependent variable is the distance it takes cars to stop.

5. The independent variable is the pill taken by the people, and the dependent variable is  the amount of weight they lost.

6. The independent variable is the darkened area or a light area, and the dependent variable is the amount of ants.

7. The independent variable is the stapler, and the dependent variable is the amount of times that staplers jammed.

8. The independent variable is the formula, and the dependent variable is the weight.

9. The independent variable is the chemical dioxin, and the dependent variable is amount of dead cockroaches.

10. The independent variable is the insulating paint, and the dependent variable is the amount of energy that each house used after a year.

Explanation:

In an experiment, there are at least two variables, the independent and the dependent. The independent variable is the one that is controlled while the dependent variable is the one that is measured. If the independent variable affects the dependent variable, then the dependent variables will depend on the independent variables.
