To test my hypothesis, I would conduct a controlled experiment where I manipulate one independent variable while keeping all other conditions constant. For example, if my hypothesis involves the effect of light intensity on plant growth, I would set up three identical groups of plants with varying light levels (low, medium, high). Each group would receive the same amount of water, soil type, and temperature. By measuring the growth of the plants over a set period, I can determine the impact of light intensity on their growth.
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
Controlled experiment. The thing you change is called the independent variable and the constants are the dependent variables. By only changing the independent variable, any results can be attributed to this.
-conditions or events that could affect the dependent variable (outcome of an experiment) but do not, because they are held constant for for both the experimental and control group.
The experiment consisted of copper pennies, 5 small beakers, and dropper bottles of: dish soap, water, ethanol, and baby oil. We had to drop these liquids onto pennies and see which could hold the most. So, what would be the manipulated, responding, and controlled variables in this experiment?
With controlled experiments it is taken into consideration what possible variables there could be and it is taken into account when conducting the experiment. This would mean that controlled experiments would produce more valid data.
No, it could be one, but that does not necessarily classify it as controlled. A controlled experiment is an experiment that has only ONE independent variable, and other variables are kept the same.
The point of a controlled experiment is to assess the effect of one variable in a life process. This could also be for a chemical process.
The controlled parts of a controlled experiment are the variables that are kept constant or unchanged throughout the course of the experiment. These include factors such as temperature, time, lighting, and any other conditions that could potentially affect the outcome of the experiment. Controlling these variables helps to ensure that any changes observed in the experiment are a result of the manipulated variable being tested.
you might not get the experiment correct (:

An experiment is called a controlled study because it involves manipulating variables under controlled conditions to isolate the effects of those variables on the outcome or results. By controlling other factors that could influence the results, researchers can more accurately determine the impact of the variables they are studying.

The independent variable.
Some controlled variables when using a lemon for an experiment could be its size, ripeness, temperature, and the method of extraction of the lemon juice. These variables should be kept constant throughout the experiment to ensure that any changes observed are due to the manipulated independent variable and not these controlled variables.

Scientists try to identify as many relevant variables as possible in order to account for potential confounding factors that could affect the outcome of the study. By identifying and controlling for these variables, researchers can increase the validity and reliability of their results, even when a controlled experiment is not possible.
