  3. Agenda: • Introductions • Tec-help info • Web Seminar Tool Training with Examples • Web Seminar Presentation • Evaluation • Chat with the presenters

  4. Let’s do a poll question! Is this your first Web Seminar? http://institute.nsta.org

  8. Let’s do a poll question! Who is in the audience? http://institute.nsta.org

  9. Top line, from right-to-left: 1. Top, right-corner, small square: minimize/maximize tool palette 2. Highlighter 3. Stamps 4. Clear and shaded geometrical figures

  10. Where is everybody?Use a stamp to pinpoint your location in the world

  11. Where is everybody?Use a stamp to pinpoint your location in the USA

  12. Top line, from right-to-left, (cont.): 5. Arrow head and tail (on/off) 6. Diagonal line (continuous or dotted): (arrowhead and tail work together with line) 7. Levels of shading from max to min. 8. Paintbrush 9. Clear button 10. Undo

  13. Watershed Dynamics:Modeling Bill Carlsen Penn State University Nancy Trautmann Cornell University

  14. Authentic Inquiry Learning science “as science is practiced” • Real questions with unknown answers • Important problems (often local) • Socially constructed through collaboration, argumentation, and critical evaluation by peers

  15. Example of a Dynamic System Image source: http://www.bbc.co.uk/schools/gcsebitesize/img/bilynxandhare.gif

  16. Modeling • Physical models - fish tank population growth • Conceptual models - parthenogenetic guppy birth • Mathematical models - coin-flipping simulation

  17. Poll 1 Have you used any of the following types of modeling software with your students?

  18. National Science Ed Standards Unifying Concepts and Processes STANDARD: As a result of activities in grades K-12, all students should develop understanding and abilities aligned with the following concepts and processes: • Systems, order, and organization • Evidence, models, and explanation • Constancy, change, and measurement • Evolution and equilibrium

  19. Problem 1 Model how land use practices affect stream flow in watersheds. What variables should be included in a mathematical model of such a system?

  22. Homegrown Analysis Your students can do land use analysis… Project GLOBE protocols: http://www.globe.gov/fsl/html/templ.cgi?measpage Or get data from elsewhere… Environmental Literacy Council land use links: http://www.enviroliteracy.org/subcategory.php/26.html Local agencies (e.g., planning, conservation, Cooperative Extension)

  23. STELLA Streamflow ModelTrial 1:0,100,0,0(100% Forest)

  24. Rainfall graphical input

  25. Student’s streamflow prediction

  26. Results: 0,100,0,0

  27. Trial 2: 50% Forest

  28. Your prediction?

  29. Trial 2 Output

  30. Poll 2 Do you think that a simulation like the streamflow model would be useful in any of your classes?

  31. Problem 2 Urban students may not live in their watershed, much see it. How to introduce the watershed concept?

  32. Approach Idea: Begin with a physical model (in this case, a physical model of a conceptual model!)

  33. Building the Model

  34. Problem 3 How do you keep a lake from filling up with green muck?

  35. You’re the Watershed Manager Your job: Control eutrophication How? • Agricultural practices • Amount of land that is farmed • Human population growth • Wastewater treatment

  36. Poll 3 You're a Watershed Manager. Your job is to control eutrophication in a lake, and a local fisherman is willing to help monitor your progress from his boat, which he takes fishing every Saturday. Which of the following would be the simplest RELEVANT variable to monitor?

  37. Possible Outcomes to Monitor • Algal density (cells / ml) • Secchi depth (turbidity) • Dissolved oxygen (D.O.) at the bottom of the lake

  38. Management Interface

  39. Results
