You can only change ONE at a time. That's what makes it controlled. It's the only sure way to know what actually changed the experiment.

How come you can't use 2 manipulated variables in an experiment?

there is only one manipulated varable in an experiment otherwise it would not be a controlled experiment

What would be the manipulated responding and controlled variables in this experiment?

The experiment consisted of copper pennies, 5 small beakers, and dropper bottles of: dish soap, water, ethanol, and baby oil. We had to drop these liquids onto pennies and see which could hold the most. So, what would be the manipulated, responding, and controlled variables in this experiment?

What is an experiment in which only one factor is allowed to vary?

A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.

Is water a variable?

It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.

Why using 2 manipulated variables in an experiment would not be wise explain?

Well, when something changes, you would not know which variable caused the change in the experiment.

What would happen if the variables in an experiment we're not in identified?

If it was not identified then you would not know what to change or what stays the same.

Well, when something changes, you would not know which variable caused the change in the experiment.

Why do variibles need to be controlled in science?

Experimental variables need to be controlled because they can cause the experiment to be flawed. Variables can change the experiment, and even if it's not a very big change, it will still make the experiment unreliable. For example, let's say a person is trying to see which laundry detergent is better. They stain four shirts with grass stains, and then apply detergent to each one. The experimental variable in that experiment is the stains; In order for the experiment to be accurate, the person doing the experiment must make sure that they put the same amount of grass stains on each shirt. Otherwise, it would be a very incorrect, inaccurate experiment.

Why is a controlled experiment important to science?

A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.

What is important for both laboratory and field scientists?

Maintaining the Scientific Method and a proper experiment with controlled variables. Probably more concern would be in a less controlled field environment.

What is a controlled varable?

Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.

What are constant and controlled variables?

Constant/controlled variables are variables that remain the same throughout an experiment. For example, if you wanted to see whether light affected how well plants grow, you would feed them equal amounts of water, so that the only variable affecting their growth was light exposure.
