What else can I help you with?
In a controlled experiment a scientist carries out two tests that are identical in every respect except for one factor?
In a controlled experiment, a scientist manipulates one variable while keeping all other conditions constant to isolate the effects of that variable. This allows for a clear comparison between the two tests, helping to determine how the single factor affects the outcome. By ensuring that all other factors remain identical, the scientist can attribute any differences in results directly to the variable being tested. This method enhances the validity and reliability of the experiment's conclusions.
What is an experiment in which all of the variables except for one remain the same?
The general term is 'controlled experiment'.
How many variables are kept constant in a experiment?
All variables except one, the experimental variable, are kept constant in an experiment.
How does a scientist dress?
normally as every one else except with caution.
Characteristics of a science experiment?
In a science experiment, the effect of an independent variable on a dependent variable is tested. The variables can be any measurable quantity. Experiments usually include a control group, a group where the level of the independent variable is "normal". All factors are kept the same for each of the runs, except for the independent variable. These unchanging factors are called "constants". The scientist usually starts with a hypothesis, what they believe is going to happen. For example consider the following experiment: A scientist wants to find the effect that Ammonia will have on the height of plants. So he sets aside several different plots of land, and places different ammounts of ammonia on each plot (measured in mass). Except for the amount of Ammonia, the conditions of each plot are exactly the same. They are given the same amount of water, sunlight, heat, type of plant, ect. The scientist records the height of each of the plants regularly, maybe every week. At the end of the experiment, all of the data is compiled, and a graph is usually made. Most rigorous experiments will include several runs to see if the results can be duplicated. The hypothesis is modified to fit the results of the experiment.

What is a role of a control group?
In conducting a scientific experiment, a scientist should have a control group and an experiment/treatment group. The scientist proposes a null hypothesis (null because it is intended to be disproven). The scientist then treats the two groups identically except the treatment group receives the treatment and the control group does not. Because the two groups were treated identically except for the treatment, any subsequent differences in the groups is (tentatively) attributed to the treatment. Thus,the control group is the group NOT receiving the treatment. For example, the scientist could propose that "fish will not die if they stop receiving food" (as a null hypothesis). The scientist then places two fish tanks full of similar fish into the same room, so that temperature, air pressure and light are equal. Then the scientist feeds one tank the recommended amount of fish food, while not feeding the other tank at all. After one week of this treatment, the scientist observes the tank receiving food (the control group) contains live fish while the group receiving the treatment (starvation) only contains dead fish. The scientist would then disprove the null hypothesis and conclude (tentatively) that fish do need food to continue living.
What is a mistake made by a scientist during a experiment?
A mistake made by a scientist during an experiment could be not controlling all variables except the one being tested, which can lead to inaccurate results. Another mistake could be not properly calibrating equipment, leading to measurement errors. Additionally, overlooking safety protocols could result in accidents or injuries.

What is the variable the scientist controls?
That depends on what you're trying to find out. Its the manipulated variable that the scientist(you) use to compare to "normal" results. Say you're doing an experiment. You have to grow two plants, but you decide you want to find out what happens to the plant if you give it soda instead of regular water. You would get two plants and you would grow them in the same exact way except that in that experiment, you would give one soda instead of water. The variable is the one thing you changed.
To ensure that an experiment is testing only one variable scientists often run a?
controlled experiment where all variables are kept constant except for the one being tested.
