A7th grade science class placed three large grade a eggs into beakers and recorded the mass. they then filled one beaker with vinegar, one with corn syrup, and one with distilled water. after 5 days, they recorded the new masses of the eggs. this can be seen in the chart below. what are the independent variable, dependent variable, and constants?

Independent- The vinegar,corn syrup, distilled water
Dependent- The mass of the egg
Constant- the egg and the beaker 

The gas would begin to expand, and eventually the can would burst or explode.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .
