1. Lillian noticed that the flowers on the east side of her home were larger and had more blooms than the flowers in the backyard. She wondered how the amount of sunlight affected their growth. She believed that if she moved her flower garden to the side of her home, the flowers grown there would be healthier and more bountiful, thereby increasing the chances that her garden would be chosen to be included in the Garden Club's walking tour this year. Lillian spent an entire weekend digging up and re-planting her flowers. According to the steps of the scientific method, what did Lillian fail to do? a.) Formulate a question b.) Test the hypothesis c.) Reach a conclusion d.) Arrive at a hypothesis

2. Which element is abiotic? a.) Bacteria b.) Seaweed c.) Oysters d.) Sand

3. Which of the following statements about Aldo Leopold and his contributions to environmental awareness is true? a.) His book discussed the negative impacts of overpopulation, including food shortages, diseases, wars and irreversible environmental damage. b.) He believed humans were ethically obligated to protect the environment as a whole because humans and nature rely on one another. c.) He was a human-centered environmentalist who believed we should protect the environment because it has many uses for man. d.) His book On Human Nature bridged the gap between biological and social sciences.

4. Which statement reflects an environmentalist stance? a.) Corals demonstrate the partnership of symbiosis in which both plants and animals benefit. b.) Overfishing and land-based pollution have damaged 20% of the ocean's coral reefs. c.) Approximately 30 million people around the world are dependent on reefs, and they have a duty to protect them. d.) Reefs are important nesting grounds for a variety of aquatic life.

12. Which of the following statements about continental drift is true? a.) Because of continental drift, the majority of most continents' landmass remains underwater, which has severely limited biodiversity. b.) About one hundred million years ago, all of the continents were one giant landmass called Pangaea. c.) After the continents were separated, continental drift slowed, until today it is almost nonexistent. d.) All of the continents were once one big super-continent, but their separation created more coastline, which was beneficial for biodiversity.

16. Which statement below about the major impacts of overpopulation is NOT true? a.) Unchecked population growth will cause migration to cities and the destruction of infrastructures such as dams and bridges. b.) Population growth will increase air and water pollution, while also contributing to the loss of ecosystems. c.) Increase in population will hasten the depletion of non-renewable natural resources and the loss of species. d.) Overpopulation will lead to further deforestation, and the loss of trees will lead to less oxygen in the atmosphere.
