so important to a controlled experiment
The experiment may benefit from having more dependent variables to increase accuracy, or a series of controlled variables.
design a controlled experiment to test a hypothesis.?
Consider the following:: your friend's car doesn't startThe process of Observation, Hypothesis, Controlled Experiment and Conclusion would involve the following:
In this experiment you need three experimental groups, each for every irrigation method (flood, spray or drip) and in this case you don't need a control group at all. In this experiment the irrigation method is the independent variable and the resulting growth rate of the radishes is the dependent variable. Treat each group of plants the same (light, water quantity, nutrition, cultivation, etc.) besides your independent variable - the different irrigation method.In an comparative experiment you can test, of course, the effect of a few independent variables but not in the same experimental group where also only one independent variable is allowed as in the case of a controlled experiment.

It is also recommended to mention additional experiments needed in order to investigate your topic further, and also your experiment limitations if you identify such (conditions or factors that you cannot satisfactory control in an experiment).

Talk to your student or contact parents directly if it seems that the parents are doing more of the work than the student is. That scenario might result in a great final product, but it will be clear to the judges at the competition that the student does not understand the project in the depth they would have had they conducted the experiment themselves.

What Is a Controlled Experiment? - ThoughtCo
In an controlled experiment you can test only one independent variable. That means that you can only change one condition in your experiment. If there's more than one independent variable in an experiment it becomes flawed. If you want to test another independent variable, you'll have to conduct another experiment. For example, if in our experiment, in the experimental group, besides the fertilizer also the amount of light is not the same as in the control group then it's impossible to deduce which condition affects the radish plants growth - the fertilizer or maybe the light intensity.

Say you want to test the effect of a certain fertilizer on radish plants growth. For this you need to create two groups of radishes: the control group and the experimental group. The two groups are treated the same (irrigation, light, etc.) besides only one factor, the fertilizer in question which is applied only to the radishes belonging to the experimental group.
