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
Example of a Dynamic System

Modeling
• Physical models- fish tank population growth
• Conceptual models- parthenogenetic guppy birth
• Mathematical models- coin-flipping simulation
Poll 1
Have you used any of the following types of modeling software with your students?
National Science Ed Standards
Unifying Concepts and ProcessesSTANDARD: 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
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?

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…

Trial 1:0,100,0,0

Rainfall graphical input
Student’s streamflow prediction
Results: 0,100,0,0
Trial 2: 50% Forest
Your prediction?
Trial 2 Output
Poll 2
Do you think that a simulation like the streamflow model would be useful in any of your classes?
Problem 2
Urban students may not live in their watershed, much see it.
How to introduce the watershed concept?
Approach
Idea:
Begin with a physical model (in this case, a physical model of a conceptual model!)
Building the Model
Problem 3
How do you keep a lake from filling up with green muck?
You’re the Watershed Manager
Your job: Control eutrophication
How?– Agricultural practices
– Amount of land that is farmed
– Human population growth
– Wastewater treatment
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?
Possible Outcomes to Monitor
• Algal density (cells / ml)
• Secchi depth (turbidity)
• Dissolved oxygen (D.O.) at the bottom of the lake
