As part of a class project, you go to the duck pond by the Miller administration building and dangle a magnet on a string into the water. A week later, when you come back and retrieve the magnet, you discover that it has a lot of bacteria on it. You want to know why. You suspect that the bacteria make granules of iron in their cytoplasm and when they swim too close they get stuck to the magnet. You take the magnet back to the lab and scrape off the bacteria into a test tube. You lyse (break open) the bacteria and measure the amount of iron in the test tube. The lysed bacteria have 100 parts per million (ppm) of iron. You also measure the amount of iron in an equal volume of pond water. The pond water only has 1 ppm of iron. You conclude that the bacteria contain more iron than the surrounding pond water and this is why they stick to the magnet. What part of the experiment was the control?
