What would a control be for a experiment to see whether fertilizer helps a plant grow?
answer: compare a plant not given fertilizer to a plant given fertilizer..
What could you do to affect the concentration of a nutrient solution?
you could put in less water and more fertilizer solution.
Why must controls such as plants given water only be used in the fertilizer experiment described in the study guided?
to elliminate soures of error

What does it meant that nitrogen burns a plant?
Nitrogen plant burns are caused when to much fertilizer (or fertilizer with a high concentration of Nitrogen) is added to a plant. If the concentration of Nitrogen (or Nitrogen compounds such as ammonia) is to high it causes the soil to become highly acidic in the area where it was applied, the high acidity damages (or kills) the roots of the plant retarding or preventing the uptake of water or nutrients by the plant.
If one plant receives extra water and the other receives extra fertilizer is these experiment controlled or not?
Not. A controlled experiment is one where there is a control - in this case what is needed is a plant which receives no extra fertilizer or water.
What is a controlled experirment?
A controlled experiment is an experiment in which all factors are controlled except for the one variable you will be altering. If you were performing a controlled experiment on the effects of fertilizer on plant growth, for example, you have to control plant variety, exposure to sunlight, soil type and water ration. The only thing you would change is the fertilizer used on each plant.
What is a test experiment that is cntrolled?
It is a controlled experiment. Take for example if you wanted to see how well a fertilizer helps in making a plant grow. All variables must be controlled except for one - the amount of fertilizer added. So you must have a control. Just stick the same plant in some potting soil with no fertilizer and add the same amount of light, water, temperature, etc as the experimental plant except add fertilizer to the one you are testing. The one that has no fertilizer is the control. You must have one of these to compare the one that you added the fertilizer to so you can see if the fertilizer made any difference. Hope this helps.
What is the control variable in the experiment does adding fertilizer to plants allow them to grow faster?
controlled variable would be light water and health of the plants
What are the scientific variables and what do they mean?
In an experiment, the independent variable is the variable that is manipulated, for example plant fertilizer. The dependent variable is what is observed and measured as a result of the independent variable, for example plant height. Controlled variables are factors that are kept constant for the entire experiment, such as temperature and moisture, so that the observed results are due only to the independent variable. So in an experiment measuring the effect of fertilizer on plant growth, the independent variable would be the fertilizer, the independent variable would be the height measured at specific intervals, and the controlled variable of temperature and moisture would be kept the same for both groups.

What is a controlled expirement?
an experiment that can be controlled i did not know this That is not a good answer! A controlled experiment is: If you set up an experiment: Example: You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day. If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!
What is a controlable variable?
A variable which can be controlled by some other variables or some other parameters is known as controlled variable. A controlled variable is something that can be changed by the experimenter. It is also known as the independent variable. It is something that gives a measure by which to gauge everything else by. For example, if you were testing the effectiveness of a plant fertilizer the "control" would be a plant that is given no fertilizer at all. A controlled variable is the variable that stays the same through out the experiment meaning no changes to it.
What do you do with fertilizer if the concentration is too high?
Dilution is what to do with fertilizer if the concentration is too high.Specifically, too high concentrations of fertilizer lead to excess growth, nutrient toxicity and soil runoff. Plant roots can take fertilizer and soil nutrients only in dissolved form. Adjust a too high concentration back to the desired level with water. Diluting adds fertilizer in a way that can be taken in by roots and soil at the same time that it contributes to soil moisture levels.
Why must controls (such as plants given water only) be used in the fertilizer experiment?
to have something to compare with the growth of fertilized plants.
