indipendante variable, dependant variable, and a control group
An experiment must have a control to show what would happen if no factors were changed.
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
You have equipment , metod and conclusion.
you must repeat and redo the experiment
An experiment is something like if we don't know if, for example, the result of salt solution. Then we must do it for real to find out the answer. An experiment is not only in the science lab. We can do an experiment everywhere, such as: Our homes, the park,... So that's what a science experiment means. People who haven't done an experiment yet must try some 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 experiment must be redone and checked for potential errors; does the conclusion of the experiment continuously disprove the hypothesis, the latter must be changed to fit.
Why must controls (such as plants given water only) be used in the fertilizer experiment
replicable, meaning that they can be reproduced by others following the same procedure. The results should also be objective and unbiased, allowing for accurate interpretation and analysis. Additionally, the experiment should be conducted with proper controls and variables to ensure validity.
