A teacher collected some beetles from a rotting log and placed them in a container of dry oatmeal in her classroom. She kept the box covered with a light cloth so that the beetles could not escape. She also asked one of her students to add potato and apple pieces once a week to provide food and moisture for the beetles. After several weeks, the student reported that there were some strange-looking, wormlike organisms in the container.
1. Formulate a hypothesis that might explain the presence of the “worms” in the container.
2. How could you test your hypothesis?
3. Identify the variables in your proposed experiment. Identify the control in your proposed experiment.
