In an experiment involving sugar water, the controlled variable would be the amount of sugar used in the solution. By keeping the amount of sugar constant while altering other factors, researchers can isolate the effect of sugar concentration on the outcome of the experiment.
The dependent variable in this experiment would be the time it takes for the sugar to completely dissolve in hot water.
The variable that depends on the controlled variable is typically the dependent variable. This variable is measured or observed to see how it responds to changes in the controlled variable during an experiment or study.
The controlled variable for making glowing water could be the concentration of the glowing compound (such as a fluorescent dye or chemical) added to the water. By keeping the concentration consistent, you can ensure that any differences in glow intensity are due to the manipulated variable (such as the amount of light exposure or type of light source used) and not the concentration of the glowing compound itself.
In a controlled experiment, the independent variable is the variable that is deliberately changed or manipulated by the researcher to observe its effect on the dependent variable. The dependent variable is the variable that is observed and measured in response to changes in the independent variable. The independent variable is controlled by the researcher, while the dependent variable is the outcome that is measured.
If you're trying to set up an experiment, the manipulated variables would be salt and sugar, and varying ratios of salt to water or sugar to water. Say you wanted to find out how fast water froze if it had sugar in it, and wanted to compare it to how quickly it froze with salt. Your controls would be the amount of water, the type of container, and the temperature of the freezer. You could pour 18 plastic cups of water, 6 plain water (the control), 6 with salt and 6 with sugar. You could also vary the amount of sugar or salt in the water (say, .5% to 2.5%, with an increase of .5% in each cup).
A controlled variable is the part of an experiment has to remain constant throughout the entire time. Example: Heating a cup of water to dissolve sugar. The temperature would change time to time, but the CONTROLLED variable would have to be the type of sugar and consistency of stirring.
The controlled variable is the type of soybean, and the changed variable is the type of water that the soybean is absorbing.
Concentration of sugar in the water
what does controlling the variable mean?
The variable for both sugar and salt is temperature: more sugar or salt will dissolve in water at a higher temperature. The amount of water is also a factor, since more water will be able to dissolve more sugar or salt.
controlled variable is something that is controlled by the independent variable
The independent variable in an controlled experiment is what you are changing (for example, amount of water or sunlight a plant gets). The dependent variable changes because of the independent variable. Its the outcome of the independent variable.
The dependent variable in this experiment would be the time it takes for the sugar to completely dissolve in hot water.
The controlled variable is the penny. The independent variable is the water. The dependent variable is the amount of water able to fit on the penny.
The variable that depends on the controlled variable is typically the dependent variable. This variable is measured or observed to see how it responds to changes in the controlled variable during an experiment or study.
Time, temperature, amount, etc. For example, how much water will flow into the container in 1 hour uses time as a relvant controlled variable.
