Abstract

The purpose of this project is to test the different concentrations of salt in still water and observe mosquito’s growth. First the experimenter filled up the beakers with fresh water and then proceeded to put different concentrations of salt into the beakers. After that the experimenter placed about 30 mosquito larvae into the beakers with different amounts of salt concentrations. The Hypothesis was is if exposed to high concentrations of salt then it will negatively affect mosquito growth. The independent variable (IV) was the concentrations of salt and the dependent variable (DV) was the number of mosquitos growing without drawbacks. The results were that all the mosquitos from the water with zero salt survived while the mosquitos in the water with 0.5 teaspoons of salt all but 2 survived. With 1 teaspoon all but 6 survived and with 1.5 teaspoons all but 5 survived. In the water with 3 teaspoons of salt had only 16 survive while 14 died. The conclusion of this was that the data supported my hypothesis of when more salt was added the rate of mortality would increase as well. These results do support the hypothesis.
