Workshop 1A: Concentrations of Pesticides on Aquatic Life (Daphnia Magna)
Session Number
Workshop 1A
Location
Room B109
Start Date

End Date

Abstract
Population growth, and the subsequent increase in pollution has led to the numerous environmental regulations, especially in the area of pesticide usage. Students will learn the effect pesticides have on heart rate, and the mortality of the Daphnia. In this workshop, I will introduce students to Daphnia Magna, a form of aquatic life. Students will then test various concentrations of ammonium sulfate, the main ingredient in pesticides, on the Daphnia. Students will then observe how the ammonium sulfate affects the heart rates of the Daphnia. The Daphnia heart is visible using a compound microscope, which students will learn how to operate. Additionally, the students will learn how to prepare their own ammonium sulfate solutions for use with the Daphnia. The toxicity level of the ammonium sulfate solutions will be tested on the Daphnia. After 1 hour, students will observe the mortality rate of the Daphnia in each concentration of ammonium sulfate to determine the toxicity level. Students will then discuss, and share data about the effects of the ammonium sulfate concentrations on the Daphnia heart rate, and the toxicity level.
