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
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.
Experiments typically involve:1) Experimental group: the group of subjects exposed to the variable being tested.2) Control group: should be as identical as possible to the experimental group, but is deliberately not exposed to the experimental variable - this provides a baseline measure from which the effect of the variable can be determined.
If all the evidence taken into consideration can be explained by the scientific model proposed and the model successfully predicts outcomes of experiments yet to be performed, it is a "good scientific theory" It still can be incorrect. If it is proven incorrect it should be abandoned.
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.
You should include answer to your problem, 1 variable, and a control group.
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

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).
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.
