What else can I help you with?
In an experiment to determine the effect of different brands of fertilizer on the rate of plant growth what are the independent and dependent variables?
The independent variable in this experiment is the different brands of fertilizer being tested. The dependent variable is the rate of plant growth, which will be measured and influenced by the independent variable.
What is the part of an experiment that you keep the same?
The part of an experiment that you keep the same is called the "control variable." This variable is used as a baseline for comparison to measure the effect of changing other variables. Keeping the control variable constant helps to ensure that any changes observed in the experiment are a result of the manipulated variable and not other factors.
In a experiment what group contains a variable?
The experimental group contains the variable being studied. This group receives the treatment or manipulation of the variable to observe its effects.
What is the constant variable for the moldy bread experiment?
The constant variable for a moldy bread experiment could be the type of bread used, the temperature at which the bread is stored, or the humidity levels in the environment. These variables are kept constant to ensure that any observed differences in mold growth can be attributed to the independent variable being tested.
What is a controlled factor in an experiment?
A controlled factor in an experiment is a variable that is kept constant or unchanged throughout the experiment. By controlling these factors, researchers can isolate the effect of the independent variable on the dependent variable. This helps ensure that any changes observed are due to the manipulated variable and not other factors.
What a variable that does not change in an experiment is called a constant?
Constant variable
What is an independemt variable?
An independent variable is the variable in the experiment that affects the other variable. For example, in an experiment that tests the affect of the amount of fertilizer on plant growth, the amount of fertilizer is the independent variable and the plant growth is the dependent variable. This is because the plant growth DEPENDS on the amount of fertilizer.
Examples of constant variable?
A constant variable is one that does not change during an experiment. If your experiment includes a dozen cupcakes and that number does not change throughout your experiment, the dozen cupcakes is a constant variable.
What variable is held constant in an experiment?
In an experiment, the variable that is held constant is called the control variable. This variable is not changed or manipulated during the experiment in order to isolate the effect of the independent variable on the dependent variable.
What is the variable that is the same in an experiment?
A variable in an experiment that stays the same is a constant.
What do you call the variable in an experiment that do not change?
Control Variable
What is the constant of the variable?
The definition of constant variable is a variable whose value cannot be changed once it has been assigned a value for an experiment. It is the variable held steady, or constant, for a specific experiment.
What is the variable that stays the same?
A variable in an experiment that stays the same is a constant.
What is a variable that kept constant in an experiment?
A variable that is kept constant in an experiment is called a controlled variable. This variable is deliberately kept the same throughout the experiment to ensure that any changes in the dependent variable are due to the changes in the independent variable.
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 the variable and constant?
The variable in the experiment that is always the same
What is the variable called that is not changed in an experiment?
constant variable
