Students receive firsthand experience using the mark/recapture method of counting a population, a technique often used by ecologists and wildlife biologists. First, students capture individuals in their simulated population and “tag” them. Then the organisms are released back into the population. After multiple trials of marking and releasing, students mathematically predict the size of the population. Lastly, students count the actual population and determine the reliability of the mark/recapture technique.
