This resource focuses on engaging students in the study of local ecosystems, particularly by tracking wildlife populations and identifying changes over time. Students will learn to recognize and analyze evidence of population changes, such as increased or decreased wildlife, and formulate hypotheses about the influencing factors. Key vocabulary terms such as 'population,' 'evidence,' 'trend,' 'increase,' and 'decrease' are introduced to enhance understanding. The document includes a visual analysis routine called 'See-Think-Wonder,' prompting students to observe and question their local environment. A case study on the fox squirrels of Oakwood Park provides real-life context, illustrating population dynamics through the introduction of resources and predators over several years. Students are encouraged to reflect on how access to resources affects population numbers, developing their critical thinking and scientific reasoning skills.
