Students will analyze population graphs, collect data to generate their own population graph, and experience limiting factors and their impact on carrying capacity in a small deer population. Students will be able to identify, explain, and evaluate the impact that different limiting factors have on the population of organisms including food, water, shelter, predation, human interference, changes in birth and death rate, changes in immigration and emigration, disease, and reproduction.

|Lesson Components||Time||Inquiry Skills||Tech. Used||Engage Level||Brief Description|
|Engage||10 min||1.3, 4.2, 4.4, 7.5||Student personal electronic devices (BYOT)||2||Students will analyze 2 different deer population graphs and make hypotheses about what accounts for the differences in the populations. Students will conduct background research on what deer need to survive in the ecosystem.|
|Explore||20 min||3.1||none||3||Students will randomly draw cards to explore how different limiting factors cause changes to their population of deer.|
|Explain||20 min||4.2, 4.4, 5.8, 7.3||none||2||Students will graph their data and respond to follow up questions about their deer population changes.|
|Expand||20 min||4.4, 5.8, 7.3||none||2||Students will choose a different animal and identify the limiting factors in their ecosystem, graphically model the population of their animal and explain the cause of changes in their population.|
|Evaluate||10 min||7.3||none||1||Students will complete a summative assessment on population dynamics.|
|Level of Student Engagement|
|1||Low||Listen to lecture, observe the teacher, individual reading, teacher demonstration, teacher-centered instruction|
|2||Medium||Raise questions, lecture with discussion, record data, make predictions, technology interaction with assistance|
|3||High||Hands-on activity or inquiry; critique others, draw conclusions, make connections, problem-solve, student-centered|
