Match each example task in Column 2 with a step of the scientific method in Column 1. List out each match in order according to the scientific method steps, and explain the reasoning for your choice.
Column 1: Scientific Method Steps 1) Observe. 2) Ask a question. 3) Create a hypothesis. 4) Conduct an experiment. 5) Collect data. 6) Interpret results. 7) Report results. | Column 2: Examples of Tasks | 8) | a) A scientist, based on his observation of the pond, believes that if a pond is exposed to the waste of an industrial plant, then the growth of algae will be accelerated. | 9) | b) In her laboratory, a scientist pours a vial of waste water, collected from the industrial plant, and adds it to a dish containing pond water. A second dish (the control dish), containing the same pond water, does not receive the waste water sample. | 10) | c) A scientist wonders if the waste water emitted from an industrial plant is accelerating the growth of algae in a pond. | 11) | d) After 5 days, the scientist measures the amount of algae present in each dish. | 12) | e) The scientist submits his findings to a scientific journal. | 13) | f) After the data is collected, the scientist discovers that the dish containing both the pond water and waste water had more than twice the amount of algae than the control dish. | 14) | g) A scientist observes that a pond adjacent to an industrial plant has heavier algae growth than ponds farther away. |

The information has a distinct pattern associated with it. When the dissolved oxygen increases so does the number of fish observed. However, when the dissolved oxygen reaches 14 ppm the number of fish decreases to 10. So, 6ppm and 14ppm, 8ppm and 16ppm, and finally 10ppm and 18ppm, have a similar number of fish observed.…

We will need enough water from the marsh to fill all four tanks needed in the Elodea experiment as well as the beakers/tupperware containers in the Daphnia portion of the experiment. This is also true for the duckweed needed from Nahant Marsh: we will need to collect enough for both tests to our hypothesis which will be enough to treat two tanks with Elodea and half of the containers for Daphnia. Once all of these materials are collected we will create our tanks to observe the Elodea. All of the tanks will have 10 Elodea plants (for the sake of replication) in 1 inch of tank rocks and filled with the water from Nahant Marsh. The independent variable in this test will be whether or not the water in each tank will be treated by duckweed and whether or not the tank will have extra nutrients (1 inch of topsoil) added. The setup of the tanks is shown in Table 1 below. Each tank will be observed for 4 weeks. Then to replicate and observe more data we will go through the process again after cleaning the tanks and disposing of the materials from the previous data…
