The ratio of hydrogen ions in the acid watering the pH 4 Plant and the pH 3 Plants were the same was the ratio between the controlled plant (B) and the pH 5 Plant, but the different in health and growth of the pH 4 Plant and the pH 3 Plants were drastically different, as reflected in Table 2. The results were that beans watered with pH 3 shrunk and began to die, pH 4 beans were growing at a slow rate, beans watered with pH 5 grew at a fairly normal pace and pH 6 grew the fastest. The controlled variables of this experiment include:

Controlled Variables Growing plants from seed requires a number of variables to be controlled. Wow, I'm sorry, but the answers given to this question are, at best, inadequate. … A controlled variable is one which the researcher holds constant (controls) during an experiment. The dependent variable is the variable that you are measuring in order to determine whether or not it is affected by a change in the independent variable. When you control for a variable, you are including it in your considerations.

independent = variable that YOU manipulate dependent = variable that changes as a result of the independent varialbe controlled = what aspects you keep constant ex: experiment in which you try how the amount you water a plant affects plant growth indp = amount of water A controlled variable remains constant and does not change throughout an experiment, while the term “uncontrolled” applies to studies where scientists can’t be certain that their test subjects are receiving the treatment in question.

These activities occur throughout the period of plant growth. In the plant experiment, the growth of the plant is the dependent variable. Overall, the more acidic the environment, the harder it is for plants to survive. The independent variable is the presence or absence of the fertilizer, while the dependent variable is the height of the plant or rate of growth. Increase in size is rapid during the embryonic period, … When doing a science experiment, some variables need to remain constant. For example, say you are trying to determine whether a particular fertilizer has an effect on plant growth. It is going to change depending on how you change the independent variable (soil) or amount of light.

An uncontrolled variable, or mediator variable, is the variable in an experiment that has the potential to negatively impact the relationship between the independent and dependent variables. Let’s say you want to know whether or not a house plant would grow better when given slightly acidic water or slightly basic water. This can cause false correlations, improper analysis of results and incorrect rejections of a null hypothesis.

Introduction. In animals. Say I want to find out a general probability of getting Lyme disease. It is the presumed cause of the changes in the plant’s rate of growth, and a change in the plant’s growth rate won’t impact the chemical makeup of the water. Although the rate of cell division differs in different regions, the capacity for cell division is widely distributed in the developing embryo.

It is also known as a constant variable or simply as a "control." Get Your Custom Essay on Effect of pH Levels on the Growth of Bean Plants Just from $13,9/Page Get custom paper. The control variable is not part of an experiment itself—it is neither the independent nor dependent variable—but it is important because it can have an effect on the results. What are independent, dependent, and controlled variables? Control Variables. By keeping a variable constant, you ensure your results remain accurate. The growth of animals is more restricted in time than is that of plants, but cell division is more generally distributed throughout the body of the organism. These are your control variables. In an "if-then" experiment, the response to a change refers to the dependent variable. Evidence gathered during uncontrolled studies can thus be inconclusive. If you don't control the amount of light (e.g., you perform part of the experiment in the summer and part during the winter), you may skew your results.
