5.29.14 Earth and EnvironmentPd. 1, 2, 7/8, and 9 Ch. 14 • Objective:SWBAT locate and describe local watershed Warm-up: Warm-up: Fill in the blanks dams aquifers resevoirs surface river watersheds Runoff that isn’t absorbed goes in to __water. It becomes part of the __ systems that are drained from larger areas called ____. Water that gets absorbed into the ground will go into ____. Rivers that have ___ on them lead to manmade ____ which help supply us with water.
Agenda: • Warm-up • Web search – watershed fun! • Watershed Assessment and Restoration Plan • Exit Slip HW = Boots Tom!! Famous at Envirothon!
Website #1: by clicking on each section, zoom in as close as possible and record the 8-digit # that includes our Loyalhanna Creek Website #2: Answer the following 1. What association does our town have? 2. Who is our local watershed specialist? 3. Use map to name 3 major watersheds in our county… not your own! Go back to top and click on “central” under Conservation Project Descriptions by Area in Westmoreland County 1. Describe in 2-3 sentences the project in Latrobe 2. Describe the GreenForge project #4 Website #3:Loyalhanna Watershed Association Go to “environmental education” under the Programs and Projects tab. 1. What 4 services do they provide to our local community in the form of education and outreach?

Capstone Water quality testing Bat boxes ORDER: Colorimeters (3) More chem pillows Squirt bottles for testing shovels
Water Quality Testing • Visual assessments • Biological assessments • Aquatic macroinvertebrate sampling • Electro-shock fishing • Chemical assessments • Nitrates = • Aluminum • Iron • Turbidity = Both indicate
Chemical assessments (water chemistry) • Colorimeter – measures the absorbance of particular wavelengths of light through a solution • Absorbance = Concentration • $700 • Precise and sensitive • Protocol is VERY important 3 teams of 4, 5, and 5 1. Practice protocol for testing samples 2. Check the accuracy of all 3 colorimeters
