Doing so can enable you to pinpoint which independent variable had what effect on the dependent variable. If more that one variable is altered, there is no way of knowing which of them actually contributed to the change without doing further experimentation.
If the experiments were worth doing, then they are worth being reported.
They all have to exact measurements for everything to make it fair
In a scientific investigation, ideally, only one independent variable should be tested at a time to accurately determine its effect on the dependent variable. This approach helps ensure that any observed changes can be directly attributed to the manipulation of that single variable, minimizing potential confounding factors. However, researchers may also consider testing a limited number of controlled variables to maintain consistency and reliability in their experiments. Overall, clarity and focus on the research question are key in determining the number of variables to test.
In a good experiment, typically only one variable should be changed at a time, known as the independent variable, while all other variables should be kept constant. This approach helps isolate the effects of the independent variable on the dependent variable, allowing for clear conclusions to be drawn. If multiple variables are changed simultaneously, it becomes difficult to determine which variable is responsible for any observed effects. Thus, maintaining control over extraneous variables is crucial for valid results.
There are 3 different variable. The independent variable is what you will be changing in the experiment and there should only be one. The dependent variable is what you will be measuring or observing. The controlled variable is what you will be keeping the same and there can be more than one. There is no limit on how many controlled variables you can have.
Independent variable
If the experiments were worth doing, then they are worth being reported.
An experiment should consist of an independent variable, which is the variable that is manipulated or changed by the researcher, and a dependent variable, which is the variable that is measured or observed to determine the effect of the independent variable.
A statement of relationship in science is typically written to explain the correlation or association between two variables. It should clearly outline how changes in one variable affect the other variable. This statement should be supported by evidence from experiments or observations conducted during scientific research.
False
The independent variable, which is the factor being changed or manipulated by the researcher, should not be changed during the course of the experiment to maintain consistency and validity of the results.
The variable that is being changed in the experiment is called the independent variable. The variable being tested is called the dependent variable. The constant is the one thing in the experiment that stays the same
You should include answer to your problem, 1 variable, and a control group.

There is no RIGHT format. Just ask the question that you are trying to answer in your experiment. For example, Why is the sky blue? This works just fine. or, What are the effects of soda (independent variable) on plants (dependent variable).
In a scientific investigation, ideally, only one independent variable should be tested at a time to accurately determine its effect on the dependent variable. This approach helps ensure that any observed changes can be directly attributed to the manipulation of that single variable, minimizing potential confounding factors.

Overall, clarity and focus on the research question are key in determining the number of variables to test.
Changing only one variable in an experiment allows researchers to clearly determine the effect that variable has on the outcome. If multiple variables are changed, it becomes difficult to identify which variable is responsible for the observed results. This helps to ensure that the results are reliable and can be accurately interpreted.
