**Standard**
Assess human population and its impact on local ecosystems and global environments (NC SCOS Biology, 5.03)

** Prior Web 2.0 Knowledge **

 * Use of Wiki
 * Use of spreadsheet program

**Length of lesson**

 * Two 90 minute classes

Learning Outcomes

 * The learner will be able to determine the health of one river system based upon three different locations in North Carolina based upon PH, conductivity, water temperature, and levels of dissolved oxygen through analysis of Internet data.
 * The learner will research human interactions that could impact the health of each river system using Web 2.0 tools.
 * The learner will research methods that can be taken to improve each river system using web research strategies and analysis.
 * The learner will create a Web 2.0-based audio visual presentation that will focus on one river system. The presentation will include information on the health of the river, human impact on the river, and methods of improving the overall health of the river.


 * Students will work in groups of 4. Tables/desks should be arranged in collaborative circles or squares. Initially, students will need to be facing the "front" of the room for a video presentation.

=DAY 1=

__ Introduction __
Length: 37 Minutes
 * {collaborative group work, writing to learn, questioning, literacy groups, classroom talk} **
 * 1) Video on Cuyahoga River (embedded in Wiki). This video can also be download to your local machine using [|http://keepvid.com/]as a .mp4 video file.
 * []
 * 1) Divide your class into group of 4 students. Each group will be investigating a different
 * 2) Wiki Discussion (Use the Tab labeled "Discussion")
 * The Cuyahoga River situation led to the creation of the Environmental Protection Agency (EPA). In your group find a different environmental disaster that has occurred in the United States.
 * 1) What happened?
 * 2) When did it occur?
 * 3) What were the environmental consequences?
 * 4) What has been done to fix this disaster? What has been done to keep this from occurring again?
 * HOMEWORK 1: Read at least one other group’s post. Find at least two other facts to add to their synopsis. Has the government done enough to fix this disaster and prevent it from happening again? Support your thoughts. Post your answers to question 1 and 2 in the discussion tab of the group's page. We will discuss these in class tomorrow.

**__ Lesson __**
Length: 50 Minutes “Today we are going to learn about how humans are impacting the environment in North Carolina by gauging the health of two different water systems. You will begin by working with your partner on one system and answering the questions about that system. Tomorrow, you will discuss your system with your entire table, explaining why or why not you believe this water system is healthy. You have 50 minutes to answer your questions.”
 * Partner Activity ** {collaborative group work, writing to learn, questioning, classroom talk} **
 * Group A (slightly more complex due to averaging values)
 * Click on “[|Neuse River Information]”
 * Instructions
 * You are viewing data about the Neuse River at three locations in North Carolina. First, click on the hyperlink below to open the data sets.
 * Your data sets have two values for every category because the USGS took readings at both the top and bottom of the river. For each category and each year, average the two values (sampling depth, water temperature, pH, and dissolved oxygen). Next, convert your water temperature average into degrees Fahrenheit. The formula is Fo = (9/5)•Co + 32
 * Open Google Spreadsheets. Create a table similar to the USGS table for each location on the river, except use the averages you found.
 * Helpful insights from EPA ([])
 * Temperature should be less than 25o C, or 77o F
 * pH should be between 6.5 and 8.0
 * Conductivity should be between 1500 and 5000 ms/cm
 * Dissolved oxygen must be above 5 mg/l. Good water is about 8 mg/l.
 * Answer the questions on the wiki
 * Group B
 * Click “[|Roanoke River Information]”
 * Instructions
 * You are viewing data about the Roanoke River at three locations in North Carolina. First, click on the hyperlink below to open the data sets.
 * Your data sets have two values for every category because the USGS took readings at both the top and bottom of the river. For each category and each year, average the two values (sampling depth, water temperature, pH, and dissolved oxygen). Next, convert your water temperature average into degrees Fahrenheit. The formula is Fo = (9/5)•Co + 32

__ Introduction __
** {questioning, classroom talk} ** Length: 30 minutes "I have read through the environmental disasters posted yesterday and have been very impressed with your posts and responses. I would like to talk a little bit more on each of these disasters." Using probing questions, such as:
 * The questions provided asked you what has been done to prevent this from occurring again. However, they did not address how we allowed such disasters to occur. Many occurred during our progression in becoming an industrialized nation. Are such disasters to be expected as other countries become industrialized? Is it the consequence of becoming an advanced nation?
 * One question asked whether you thought the government has done enough to prevent this disaster from occurring again? There seemed to be differing views. What made you come to these conclusions?

__Lesson__
Length: 50 minutes "We are now going to go back to the river ecosystems that you each investigated with your partner. First I would like you to discuss what you discovered with your group for 10 minutes. We will then discuss each system as a class, so make sure you understand each river system's results so that you can participate." "That was some great discussion! I am now going to give you 20 minutes to begin working on your weekly project. Directions are on the 'Weekly Project' page. Let's look at them now so that we can make sure you understand what you are to do. The rubric is provided at the bottom of the page."
 * Group Discussion (10 minutes) ** {collaborative group work, questioning, classroom talk} **
 * Share your findings with the other group at the table. Use the explain how the health of the river has changed over time and what its current health is.
 * Class Discussion (20 minutes) ** {questioning, scaffolding, classroom talk} **
 * Have class discussion about one river system and the health of that river based upon the students prior group discussion
 * Weekly Project (20 minutes to begin) ** {collaborative group work, writing to learn, questioning, literacy groups, scaffolding, classroom talk} **
 * Choose one of the two rivers to complete your project.
 * Go to Google Maps and plot the general locations of the three checkpoints given in the daily activity. Put the map in Terrain View. This will help provide you with a general region that impacts that specific river.
 * Research four ways humans are impacting that specific river. Make sure to reference each way discussed.
 * Based upon how humans are impacting the river, research three methods that can be used to help improve the river. Make sure to reference each method discussed.
 * Create a 5-7 minute audio visual presentation that includes the four bullets above. Be creative. Make sure to load it on the presentation page so that everyone can see your presentation.
 * Watch all five videos. Comment on at least one video about something you found interesting or something that you learned.
