Experiment 1: Effects of Water Pollution on Plant Diversity
Water pollution can have severely negative effects on biodiversity and ecosystems, particularly on plant populations. In many cases, these pollutants are introduced to the environment through everyday human activity. In this experiment, you will contaminate several water samples, as well as purify a water sample. You will then evaluate the effects of water pollution and purification on the biodiversity of wildflowers.

Answer =
5. Develop a hypothesis regarding how using contaminated or purified water might affect plant biodiversity. Which pot do you believe will contain the greatest biodiversity (greatest number of species)? Why?
Hypothesis =

7. Alum contains aluminum. Research the effects of aluminum on plants by finding a scholarly source online. Does your research provide any insight into your results? Discuss your findings as they relate to the results of your experiment.
Answer =
8. Imagine that each pot was a sample you found in a group of wildflowers. Based on the diversity of flowers in each pot, would you consider the ecosystem to be healthy? Why or why not?
Answer =
9. How does biodiversity contribute to the overall health of an ecosystem? Provide specific examples and utilize at least one scholarly resource to back your answer.
Answer =
10. Rank the following three scenarios in terms of having the most to least biodiversity and provide your rationale for these rankings.
· A vacant lot behind a car repair facility.
· A designated national wilderness area.
· A grassy strip along the highway.
