Eager ecology learners read about characteristics of the Lake Erie water snake and the round goby fish. They find that the goby is an invasive species, introduced to Lake Erie in 1990, and has since had an impact on the water snake population. Pupils examine and graph water snake diet data and relate it to the introduction of the goby by answering 10 questions. This lesson provides experience with real-life data and a common occurrence in many of our waterways.
