Students in 6th grade science classes have been working to answer the question “What can cause populations to change?” To help them answer this question, students explored the predator/prey relationship between the invasive sea lamprey and the trout population found in the Great Lakes region. Students spent time learning about the lamprey and the trout, examined historical population trends, and made predictions about the decline in the native fish populations. To conclude our case study, students dissected a sea lamprey and a perch. Students were looking for clues to support their claim that sea lampreys are a major predator in our Great Lakes. Students were definitely surprised to see egg filled sea lampreys and the long intestines of a perch. Be sure to ask your 6th grade about their dissection!
