Essential Question (EQ): Which contaminants impact drinking water quality and how can we remove them from drinking water?

 

Project Description:

 

You are a part of a team of environmental engineers that specialize in water quality. After a recent contamination followed by a “boil water” advisory, local government officials —including city engineers, planners, and waste water treatment experts— have requested that you conduct an investigation and suggest a system for filtering contaminated water. The city would like to suggest a solution for individuals in the community to use in times of prolonged contaminations without continuously boiling water. Your team must identify contaminants and separate and document the amount of each of the various contaminants. You must then demonstrate a method to effectively remove contaminants from water.

Following your investigation, you will deliver a presentation to a panel of local government officials to deliver your results. Additionally, you will build a prototype filter that will treat contaminated water.

 

You will begin by researching academic and technical texts on water contamination and purification, and participating in enabling learning activities intended to assist you in designing, building, and testing a water purification system. Using the information learned, you will write a proposal in which you discuss water contamination and evaluate your system’s ability to help in times of prolonged contamination. Be sure to support your position with evidence from your research.

 

Your team will present your action plan, highlighting your team’s findings and research. The plan should show all present contaminants and their quantities graphically. It should show your results from your experiments, answers from your interview questions, and input from experts, multi-view drawings, and a demonstration of your working prototype. It should also include identified tolerances in the treated water and a plan for prevention of further contamination.

 

 

 

Key Question: How do we conduct initial research related to our filtration investigation?

 

Enabling Learning Activities:

 

Task 1: Annotation is engaging in an active conversation with a text and assists in deepening comprehension. The list of articles below can be understood more clearly by using a tool like annotation. For each of the three articles, individually use the following procedure to annotate your texts:

 

          Circle unfamiliar words.

          Write questions you have in the margins and place an arrows pointing to the sections or sentences in the text that elicited the question.

          Write in the margins connections you make to information you and your team members already possess with arrows pointing to the sections or sentences in the text that relate to these connections.

          Highlight ideas you would like to explore further that seem to relate to your project

Task 2: When you have completed your annotation, move into your teams. Share the results of your annotations with one another and reach a consensus on the questions, connections, and ideas most relevant to your project. Tape clean copies of the articles in the middle of a large sheet of chart paper. Using a marker provided by your teacher, write the agreed-upon annotation on the chart paper. This should be written large enough to be read when the chart paper is displayed.

 

Task 3: Discuss and assign one team member to have primary responsibility for each of the follow

                    Credibility Checklist   WebsiteCredibilityChecklist.docx

                    Vocabulary Log Setup – The Vocabulary Log is set up with three columns on a single page in the Engineering Notebook, one column for the vocabulary word, one column for the formal           definition, and one column for a definition in the team’s language.

Task 4: As a team use the resources from Task 3 to conduct and document research, using the following Dependent Vocabulary to assist in finding relevant sources:

 

Groundwater Filter

Contamination (water) Infiltration

Water Treatment Pollution

Nonpoint Pollution Purification

Activated Charcoal (in filtration) UV Light (in filtration)

 

Task 5: In your project teams, look at your preliminary research questions as you consider the following:

 

          What are our limitations?

          What don’t we know yet?

          What things do we need to solve?

          How will we know when we are successful?

 

Task 6: Use the answers to the above questions to generate a list of criteria and constraints.

 

Task 7: As a team, write a tentative problem statement, using all previous research and the constraint and criteria analysis as guides. Focus on the overall question, “What problem are we trying to solve?”
