You need to describe the experiment; how else can anyone know what is being manipulated?

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
If there is a plant one have light and the other have no light so is it a control experiment?
Yes cause there is only one variable that is being manipulated
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 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 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.
What is the independent and Dependent variable in will fish tank water and tap water differ when used for tomato plant growth?
the independent of the tomato plant is the leaf and the dependent variable is the root
Another name for manipulated varible?
An independent variable. This is because you can manipulate the variable so it is said to be independent of the other variables. This is different from the dependent variable which is the variable you are measuring the change in. For example in an experiment to see how the amount of water given to a plant affects it's height, the amount of water is the independent variable, because it is the variable you can change, while the height of the plant is the dependent variable because we want to see how the change in the amount of water affects it.
What is the difference between a manipulated variable and measured variable?
The manipulated variable is the variable which researches change, while the measured variable is the variable that changes as a result of the manipulated variable. Consider this simplified question: Do flowers grow better with more water? Researchers plant flowers and put 10mL in one pot, 20mL in another, and 30mL in another. This is the manipulated variable. Researchers measure how tall the flowers are. The height of the flowers is the measured variable, because it changes as a result of the amount of water added.
In an experiment what is a variable?
it is anything you can experiment on in you project The variable in the experiment allow you to test alternate possible situations and solutions to confirm the validity if the experiment or to disprove it.
What is the dependent variable in a science experiment?
The dependent variable is the effect of an independent variable. For example, if a science experiment is done with plant growth under a certain amount of light, the height of the plant is the dependent variable because it depends on the amount of light.
Why is it so important to control variables in an experiment?
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
