Agroup of students is investigating how the addition of salt impacts the floatation of an egg in water. four identical cups were taken for the experiment. the data of the experiment are shown below: experimental record cup amount of water (ml) amount of salt (g) level of egg above water 1 450 0 sinks to bottom 2 450 68 2 cm 3 450 136 3 cm 4 450 272 4 cm what was the dependent variable in this experiment? density of water in the cup level of egg above water amount of water in the cup amount of salt added

The answer is the level of egg above water.

Explanation:

The dependent variable is the variable that depends on something else to change.

The independent variable is the variable that changes. It also makes the dependent variable change.

The controlled variable is the variable that stays the same throughout the experiment.

For example, the independent variable in this experiment is the amount of salt that is added. The dependent variable is how the egg floats, or, in other words, the level of egg above water. The controlled variable is the amount of water in each cup.

Level of egg above water.
