if your doing an experiment about if sugar or salt will caused fermentation within the yeast.and you have Cup 1 with 2 cup of warm water ;2tsp of yeast and 2tsp of salt. Than cup 2 contains warm 2 cups of water:2tsp of salt and 2tsp of yeast Finally cup 3( this is the control group)you have 2 cups of warm water and 2tsp of yeast.What will be your independent variable and dependent variable
Cup 1 and 2 are the same.
An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A dependent variable is the response or measure of results.
In this experiment, the independent variable is the substance being tested - either sugar or salt. You are comparing the effects of sugar and salt on fermentation in yeast.
The dependent variable, on the other hand, is the outcome or result of the experiment that is being measured. In this case, the dependent variable is the fermentation rate. You will observe and measure the amount of gas or bubbles produced by the yeast, which indicates the fermentation process.
To determine the effects of sugar and salt, you will need to compare the fermentation rates in each cup: Cup 1 (sugar), Cup 2 (salt), and Cup 3 (the control group). By comparing the results from the different cups, you can determine if sugar or salt influences the fermentation process differently.
