What else can I help you with?
List some variables that can change in an experiment and discuss the importance of a control group?
list some variables that can change in an experiment?
What are the variables used in the experiment on germination?
water and light
In gr8 science fair if it says show the other variables controlled what does that mean?
When you prepare a science experiment you have different variables (or conditions) that you must either control (manage) or measure.Examples of variables that can be controlled include:TemperaturePressureConcentrationQuantityThey are called variables because they can be varied while you repeat an experiment. I.e. you can measure how much sugar dissolves in a liter of water. By varying the temperature you can test how this affects the amount of sugar that is dissolved.
What variables used in experiment the mongo seeds?
sunlight,water,soil and space.. temperature
How do you figure out the variables in a science project?
The variable that you change is the independent variable(which you change). This could be the amount of light, fertilizer or salt that you give to a plant to observe how it affects its growth. What you measure is the dependent variable(the variables that change due to the change in independent variable) eg mass of the plant each day or week, number of leaves or height. All other variables are called the control variables(variables that are constant throughout the experiment). These make the experiment a "fair test". In the above experiment if you were to vary the amount of salt in the soil then each plant must be given the same amount of light, fertilizer, water etc.

What is manipulated variables in experiment about boiling point of water?
Manipulated variables are variables that a scientist deliberately adds in to tweak the outcome of his or her experiment. For instance, a scientist may choose to add certain compounds into a pot of water to see if it may affect the boiling point.

Why is water used as the control sample?
Water is often used as a control sample because it is a neutral substance that does not interfere with the experiment. By comparing the results from the experimental samples to the control sample of water, researchers can more accurately determine the effects of the variables being tested. Additionally, water is readily available, inexpensive, and easily controlled for consistency.

How can you calculate the volume of H2O needed for a specific experiment?
To calculate the volume of water (H2O) needed for a specific experiment, you can use the formula: Volume Mass / Density. First, determine the mass of water required for the experiment. Then, find the density of water, which is approximately 1 gram per milliliter. Divide the mass by the density to calculate the volume of water needed.
In biology what does control mean?
In biology, a control is a standard used for comparison in an experiment to ensure that any changes observed are due to the factor being tested and not other variables. Controls help to minimize the impact of confounding variables and confirm the validity of experimental results by providing a baseline for comparison.

Can control in an experiment be changed?
no the control is that which is used to test your hypothesis. if mentos would blow up if you use caffeine and you used water, coke, and milk the water would be the control without it you cant do an experiment.
Is water a variable?
It can be, it depends on your experiment. Independent variables are the variables in an experiment that will not change. If you want to do an experiment that tests how something reacts with water, then starting with a clean controlled water sample for each test would be necessary and an independent variable. Conversely, if you were testing the cleanliness of multiple water sources, then the ideology of clean water would be your dependent variable, which would change upon each testing. WIth your given information I cannot say whether or not you would want water to be either a dependent or an independent variable for your experiment.
Can there be more than one independent variables in a experiment?
In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.
