One time when ms ryland went to the grocery store shee bought all the type of microwave popcorn that the store had with these types of pop corn she conducted an experiment
scientific question does the amount of butter on the kernels affect the amount that pop
give the independent variable and dependent variable and constants

Independent variable is what is being changed in the experiment. In this case, the independent variable is the microWave popcorn. Dependent variable is what is being measured. In this case, we are measuring the amount of butter. Constant is what stays the same in the experiment. The constant is same amount of butter, same amount of popcorn , same temperature and so on and so forth.
