Where does our water come from?
CW - 9/24 Watershed introduction - examine the map of Pennsylvania and sketch out the watersheds. How many are there? What is our watershed? What are some natural and anthropogenic causes of change to watersheds? - Watershed maps - About watersheds - Natural agents of change - Man-made agents of change

Water Pollution
What is point and non-point pollution? Who causes them? How do you clean them? Which is easier to fix? - Protecting Water

Water Treatment
Cleaning water for use by home and business consumers CW - 10/5 - Reclaimed water and steps in water treatment - Wastewater treatment - Reclaimed water - Treatment process

How do you clean the water?
Lab - 10/6-10/12 Using the Sweetwater treatment process as a model, and the given materials, how clean can you get the water? -Write the procedure -Perform the cleaning process you designed, adjusting as necessary -How clean is your water?

Group 1 - Claudia, Ben, Eva, Andre Group 2 - Colin, Casey, Sam, Kourtney Group 3 - Matt, Alec, Josh, Ron Group 4 - Chris, Megan, Kelsey, Avery Group 5 - Caleb, Cooper, Paige, Cameryn Group 6 - Connor, Priscilla, Deryk, Amber, Kylin
 * Lab Reports here - Due Tuesday at 8:00 am **.

On your group page, copy and paste this, then complete: The lab report is a group grade, based on the completeness of your procedure and the answers to these questions. However, everyone in the group needs to participate! If there is no record in the page history of any work by a group member, that group member will not receive credit! This lab is worth 20 points (as much as a quiz grade!) so do your best work. **
 * 1) Write all of your names at the top
 * 2) Write up the list of materials you used
 * 3) Write up the actual steps you performed to clean the water.
 * 4) Write up your observations. Be very specific as to what the water looked and smelled like after each step!
 * 5) Answer these questions:
 * 6) What were you not able to remove?
 * 7) How might you be able to remove it from the sample?
 * 8) How was your treatment process like that of the Sweetwater plant?
 * 9) How was your treatment process different?

River and Stream Health
How do we know how "clean" or "healthy" a river is as an ecosystem? Look at the organisms that live there! Lab 10/14-16 Macro-invertebrates as "Indicators" (Intro/Notes on Macro-Invertebrates and practice identifying!) Materials:
 * Water samples (from the Tacony Creek, aka Station Creek) with rocks
 * Dissecting microscope
 * Hand-lens
 * Eye-droppers
 * Tweezers/forceps
 * brushes
 * petri dishes

Procedure: To complete the lab report on the following pages, please copy/paste and answer these questions:
 * 1) Before you touch anything, stand very still and look at the water sample in your bin.
 * 2) Use the eye-dropper to suck up moving creatures and place them in a petri dish
 * 3) Examine using the hand lens and the microscope and use your "Identification Guide" to name each organism.
 * 4) Continue by identifying everything you see, brushing the rocks off and watching for movement.
 * 5) Count everything!!!
 * 6) Fill in the chart below and calculate the "Save Our Streams Multimetric Index" to decide the health of the local branch of the Tacony Creek!
 * Lab reports due Monday at midnight! **
 * 1) Your Names at the top (first names only, please!)
 * 2) What was the "Multimetric Index" for your water sample?
 * 3) Is the stream acceptable or unacceptable?
 * 4) What did you observe that made the stream acceptable or unacceptable?
 * 5) What do you think might be some point or non-point sources of pollution in the creek?
