Population Dynamics Unit Portfolio Presentation Jennifer Tate Unit Summary The earth is home to many different life forms, including plants, animals, humans, and other organisms. Populations of various species co-exist within an ecosystem, often having to compete for limited resources of food, water space, and shelter. The human population has grown at a constantly increasing rate over the last two centuries. This growth has resulted in changes in landscapes, oceans, and atmosphere that interfere with life-sustaining natural systems. These systems when out of balance endanger the survival of many plant and animal populations. Curriculum-Framing Questions • Essential Question How do interactions among species affect the world? • Unit Questions Why is the interaction of an organism essential for its survival? What affect does increased population have? How does habitat destruction affect biodiversity? How does human activity affect the environment? • Content Questions What abiotic factors affect the growth and survival of its survival? What is pollution? What steps can humans take to reduce their impact on the environment? Why has the human population increased? What is natural selection and how does it work? What is adaptation? Vision of What I Hope to Accomplish This project will help my students develop 21st century skills by: ☻Acting on creative ideas to make tangible and useful contribution to the domain in which the innovation occurs. ☻Understanding the interconnections among systems. ☻Demonstrating ability to work effectively with diverse teams. Gauging Student Needs Assessment Purpose of the Assessment To gather information about what students already know and what they wonder about population growth. What I want to learn from my students? I want to find out what they already know about the unit questions and interactions among populations of humans, plants, and animals. How I have tried to promote higher-order thinking? I ask students to find relationships and draw conclusions about population dynamics. How does the assessment information help me and my students plan for upcoming activities in the unit? I can identify misconceptions and plan my lessons around those misconceptions. What feedback or additional ideas I’d like? I would like help on my assessment. I think I need to elicit more higherorder thinking, but I’m not sure how. My Goals for the Course • Find ways to get my students more interested in learning science • Learn about different kinds of technology my students and I can use • Share ideas with other teachers Goals for My Students • To learn how scientists collect and think about data • To become more independent learners
