Ready-Set-Tech: New York City Water Quality Assessment Project
New York City Water Quality Assessment Project


This project is designed to support an integrated science curriculum. Students learn about the chemistry of water and how its molecular structure supports life through its biochemical, physical, and environmental roles. Students investigate the quality of water as it interacts with the environment, determining how these components affect ecosystems. Finally, students analyze case studies of a water body in their area and make recommendations to the community about the current drinking water and water ecosystem.

Students are accountable for their own learning in order to educate their peers, staff, and parents of the school community. A WebQuest with structured research activities helps guide students through their experiments and interpretation of data. Other resources include an audio-streamed NPR segment on the vitality of the Hudson River. With connection to Thirteen-Online, the students published their results online with the goal of community activism in mind.

•  Students become aware of a Hudson River ecological problem linked to urbanization, industrialization and sprawl.

•  Students generate their own questions for investigation throughout their water quality research.

Materials Check List:

•  Access to NPR radio archive online at (“Hudson River Trouble”) http://npr.org/features/feature.php?wfId=1117383

•  Class computers with access to the Internet for the Water Quality Assessment Webquest http://webquest.mschien.com

•  Large pieces of paper for investigative questions, one per class.

Pre Class Activity: None

Aim: What's the big deal about the Hudson River?

Do Now (Individual): The Hudson River is a vital part of New York State and New York City. List at least 10 things that you know about the Hudson. Feel free to share some experiences you had, or would like to have (Circle Line, railroading, camping, etc) on the Hudson River.

THE CLASS WORKSHOP

Class share: Class share their DO NOW responses.

Introduce NPR radio show about the Hudson River. Instruct students to listen carefully for any new and interesting information about the Hudson.

Individual Activity: Free write—What is some new information you've learned about the Hudson River? In what ways do you see yourself connected to the overall issues of urbanization and industrialization?

Pair share/Class share: Pair-share individual responses. Students then class-share their chats about the radio show. Be sure to clearly define the meaning of urbanization, industrialization and sprawl in environmental science.

Introduce the project by presenting the case to the students as water quality scientists working for the EPA. Present past student data on the website, and emphasize the students' job to contribute to the annual School of the Future monitoring of the water quality of the Hudson River. Emphasize that their results will be published online for the public to view.

Pair Activity: Students brainstorm questions about Hudson River water quality they want to investigate.

Class Share: Students share questions for investigation. Questions are then documented on a class poster board for constant reference and research.

Students will be given their research teams. Teams are assigned to a specific water quality component (2-3 person group). Demonstrate the WebQuest that accompanies the research project to help guide their ultimate product.

Team Engagement: Teams breakout onto class computers and browse the WebQuest for 10 minutes. Teams assign a team facilitator, resource person and team leader.

TALK ABOUT FOLLOW UP FOR HOMEWORK

Download the TASK SHEET off the WebQuest and complete question #1-2 under Research Decomposition. Be prepared to meet with your teams tomorrow to present your understanding.

CLASS WRAP-UP

Instructor should utilize this time to answer any technical and logistical questions about the WebQuest.

 


Day Two:


Title: Engaged as Young Scientists – The Water Quality Lab (in-field or laboratory setting)

Instructional Objectives:

•  Students utilize the scientific method to examine their assigned component of river quality.

•  In their research teams, students share and refine their understanding of their assigned water component.

Materials Check List:

•  Water quality testing kits

Pre Class Activity: Previous assignments need to be completed to actively participate in team activities.

Aim: Getting Down and Dirty – What IS the quality of the Hudson River Water?

Do Now: Break out into your teams. Share your homework assignments. Team leaders need to assure that all team members understand the nature of their water component. Team resource person obtains a class transparency to bullet point key information of their specific water component. Team facilitator leads in discussion using the TASK SHEET questions as a guide. (The transparency will serve as a tool for class team share later, as well as a resource when they sketch out the layout of their webpages).

THE CLASS WORKSHOP

Class presentations: Teams present their research findings via overhead. Presentations should be 2 minutes each. ALL students must take notes on WATER QUALITY RESEARCH MATRIX as each team contributes.

Research team challenge : Research teams break out and conduct water quality exams on 3 samples of water from 3 points on the Hudson River. Teams note results in their field journals for record and for later jigsaw activity.


Team meetings : After results are taken, teams sit and examine results. Use RESEARCH DECOMPOSITION QUESTIONS #4 and #5 to guide your meeting.

TALK ABOUT FOLLOW UP FOR HOMEWORK

Individually, complete questions 4 and 5 of RESEARCH DECOMPOSITION on your TASK SHEET thoroughly. Be prepared to use your previous research and your data to support your thoughts. Expect to contribute to your teams tomorrow.

CLASS WRAP UP

Class brainstorm on possible error analysis in their experiments. Teacher should jot down ideas and responses on poster paper so that students can refer to them as they create their team report.


Day Three:


Title: Looking at Connections within Water Quality

Instructional Objectives:

•  Research teams establish their conclusion about their water component.

•  Teams interact with other teams to share results.

•  Students understand that water components and characteristics work interdependently with one another in maintaining river health and stability.
