How can pesticides affect nontarget plant life?
Leaching and runoff can cause pesticides to move away from their target location. When pesticides mix with rain or irrigation water, they can seep into the soil and travel to another area where they can affect the plant, animals, and environment. In this experiment, you will examine the effects of pesticides on new growth. You will plant a lettuce seed and nurture it with water that has insecticide in it. Planting three sets of seeds, you will add two varying amounts of insecticide to the water and compare them to lettuce grown in unaltered water. Before you begin, make an educated guess about the outcome of this experiment based on your knowledge of leaching, runoff, and pesticides.
