A+ Only one variable is changed at a time.
The conclusion of a controlled experiment must be based on the results obtained from the experiment itself. It should directly address the research question or hypothesis posed at the beginning of the experiment. The conclusion should also highlight any patterns, trends, or relationships observed in the data collected during the experiment.
The factor that changes in a controlled experiment is called the independent variable.
The controlled parts of a controlled experiment are the variables that are kept constant or unchanged throughout the course of the experiment. These include factors such as temperature, time, lighting, and any other conditions that could potentially affect the outcome of the experiment. Controlling these variables helps to ensure that any changes observed in the experiment are a result of the manipulated variable being tested.
A controlled experiment might be impossible if there are too many variables that cannot be controlled or if it is unethical or impractical to manipulate certain variables. Additionally, external factors outside of the researchers' control can also make it difficult to ensure a controlled environment for the experiment.
A factor being measured in a controlled experiment is a variable that is deliberately changed or manipulated by the experimenter to see how it affects the outcome of the experiment. Factors are typically independent variables that are controlled to observe their impact on the dependent variable being measured.
controlled experiment
TRUE!!!
TRUE!!!
Not all hypotheses can be proven, no matter how well controlled.
experiment
true
A controlled experiment is better than a none controlled experiment because you can control one of them and the other you can't. Science is a really fun subject.
False
False
False
An investigation in science that is controlled is an experiment. The group within the experiment that is controlled is the control group.
a controlled group is like an idea but an experiment that is controlled cannot be changed.
