Two students decide to test what factors influence water absorption by an egg. they create three different water solutions. one is pure,
100% distilled water, a second is 50% water and 50% corn syrup, and the third is 100% corn syrup. the mass of each egg is measured
before they are put into a single solution for 24 hours. the mass of the eggs is then measured, and the data recorded below:
type of solution
distilled water
50/50 mixture
100% corn syrup
starting mass
65.1 g
62.09
66.7 g
ending mass
77.8 g
52.2g
48.9 g
change in mass
12.7 g
-9.8 g
-17.8 g
this group also recorded a dependent variable, which is represented by
a. the change in the mass of the eggs.
b. the starting mass plus the ending mass of the eggs.
c. the amount of time they were in the solution.
d. the type of solution the egg is placed in.
