The purpose of this study was to see if there is a link between global climate change and an increase in mosquito populations and mosquito borne disease. Students came up with two research questions: 1) How does climate change affect mosquito populations? and, 2) How do changes in precipitation affect mosquito populations? The three hypotheses tested were: populations of mosquito larvae increase as rainfall amounts increase, the heavier the rainfall, the more likely mosquito larvae will be found in sitting water within a few days, and one effect of climate change is heavier precipitation events, which leads to increased mosquito populations because of more sitting water. Students collected water samples and looked for mosquito larvae around our school's campus as well as recorded rainfall amounts at our school's weather station. Students also collected atmospheric data using the one-day integrated weather data sheet and followed GLOBE protocols. The data collected showed that mosquito larvae increased as rainfall increased. The data also showed that the heavier the rainfall, the more likely mosquito larvae will be found in sitting water within a few days. Historical data seemed to show that mosquito larvae increased when there was a heavy precipitation event following a dry period. For the most part, students' hypotheses were supported by the data. Further research needs to be conducted in order to see if global climate change has an effect on mosquito populations and an increase in mosquito borne diseases.
