In a similar experiment to the one described in number 2, classes will look at the effects of fertilizer on the growth of duckweed.
Classes are interested in what impacts pollution has on streams and local water bodies.
Students theorized that fertilizer from local agricultural lands would have an impact on the vegetation of streams, ponds and lakes near the agricultural land. To test this hypothesis, students will add differing nutrient loads to experimental continers of duckweed, and monitor the increase in duckweed over time in these containers. The idea for this experiment is very similar to the one described in number 2. Additionally, students will explore the pros and cons of fertilizer, and draw conclusions regarding the effects of increased vegetation in aquatic systems.
