What is the manipulated variable in a tomato plant?
In a tomato plant experiment, the manipulated variable is the factor that the researcher intentionally changes, such as the amount of sunlight, water, or fertilizer given to the plant. This variable is controlled by the experimenter to observe its effects on the plant's growth and development.
Which of the following best describes a manipulated variable?
Fifteen turtles are fed iceberg lettuce and vitamins, while another fifteen turtles are fed only iceberg lettuce
In an experiment the hypothesis is If the wavelength of the light shining on a plant is shortened the rate of photosynthesis is slowed down. If this experiment is performed the independent variable .?
The independent variable in this experiment is the wavelength of the light. This is because it is being manipulated or changed by the researcher to observe its effects on the rate of photosynthesis in the plant.
What were the controlled variables manipulated variables responding variables?
In an experiment, controlled variables are the factors that are kept constant to ensure that any changes in the experiment are due to the manipulated variable. The manipulated variable is the one that is intentionally changed or controlled by the researcher to observe its effect. The responding variable, also known as the dependent variable, is the outcome being measured or observed in response to changes in the manipulated variable. For example, in a plant growth study, the amount of sunlight could be the manipulated variable, while the height of the plants would be the responding variable, and soil type and water amount would be controlled variables.
Use independent variable in a sentence?
The independent variable in an experiment is the one that is manipulated in order to test a hypothesis. There will also be a control used in order to make sure that the variable is doing what it is supposed to.
What are the independent and Dependant variable in a science experiment?
In a science experiment, the independent variable is the factor that is deliberately changed or manipulated by the researcher to observe its effects. The dependent variable, on the other hand, is the outcome or response that is measured and is expected to change in response to the manipulation of the independent variable. For example, in an experiment testing the effect of sunlight on plant growth, the amount of sunlight (independent variable) is varied, while the plant growth (dependent variable) is measured.
What are examples of a responding variable in a lab investigation?
It's what changes when you alter the manipulated variable. Examples: In an experiment testing how tall anplant grows in different amounts of sunlight - the manipulated variable is the sunlight, the responding variable is the height of the plant. In an experiment testing how much carbon dioxide produced when different amounts of baking soda react to vinegar - the manip. variable is the baking soda amount, the resp. variable is the carbon dioxide. In an experiment testing how different vitamins affect a person - the manip. variable is the vitamin, the resp. variable is the effect on the person.
What is an independent variable in a scientific experiment?
An independent variable in a scientific experiment is the factor that is deliberately changed or manipulated by the researcher to observe its effect on the dependent variable. It is the condition or treatment that is varied to test its impact, allowing scientists to establish cause-and-effect relationships. For example, in an experiment testing the effect of different amounts of sunlight on plant growth, the amount of sunlight is 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 a independent vairable?
The object you are testing in a hypothesisThe Independant or manipulated variable is what 'I' or you are changing....if you are measuring the effect of fertilizer on plant height, the Independant variable is the presence/absence of fertilizer.
What is the difference between indepedent and dependent variables?
In a science experiment, the independent variable is the one you change. For example: if you are doing an experiment on the impact of different types of soil on plant growth, the different types of soil would be your independent variable. The dependent variable is the outcome, or whatever the independent variable directly impacts. In this case, the dependent variable is the height of each plant.
What is the independent value?
The independent variable is the factor that is manipulated or changed in an experiment to observe its effects on a dependent variable. It is considered the cause in a cause-and-effect relationship. In an experiment, researchers deliberately alter the independent variable to test its impact on the outcome. For example, in a study examining the effect of fertilizer on plant growth, the amount of fertilizer used would be the independent variable.
