ARRT LESSON

 

LESSON TITLE:  Xplorer Water Quality Field Test

 

AGE OR GRADE LEVELS:  11-12 Grades

 

THIS IS LESSON#_2 OF A UNIT TITLED Water Quality of Shantee Creek

 

CENTRAL QUESTION: Can students use probe ware to effectively quantify water quality of our sample site?

 

IDEAL STUDENT ANSWER TO CENTRAL QUESTION:

Yes, with good instructions they will feel they can use the tools correctly.

 

SPECIFIC GOALS FOR THIS LESSON:

  1. Students will become more interested in environmental issues.
  2. Students will value the local water system.
  3. Students will understand problems facing our creek systems.

 

SPECIFIC MEASURABLE OBJECTIVES OF THIS LESSON:

  1. Students will be able to measure water quality using Xplorer probe ware technology.
  2. Students will be able to analyze data collected with probe ware.
  3. Students will be able to understand the parameters of the four water quality tests.

 

SPECIFIC OHIO STATE MODEL COMPETENCIES:

ODE-LS: F-15 Explain how living things interact with biotic & abiotic components.

ODE LS: G-18 Describe ways that human activities can deliberately or inadvertently alter ecosystem.

 

STUDENT PROBLEM AREAS:

  1. Technology does the analysis for you.
  2. Water quality tests are not related to each other.
  3. “Fixing” problems of creek systems is quick & or simple.

 

 MATERIALS NEEDED:

Xplorer probeware kit (sensor, DO, Temp, pH, Conductibity probes)

Rinse bottle (distilled Water)

Optional: Hach snap kits for comparison of data.

 

TEACHING STRATEGY:

            * note: students would have already read & practiced with probeware before this.

  1. Intro/Motivator:Bill Nye Video:”Stream keepers”
  2. Review Probeware instructions & map testing area.
  3. Students will be sent to specific creek area(2 groups upstream & 2 groups downstream)  & will follow probeware procedures to chart 4 water quality parameters: Dissolved Oxygen,pH,temperature & conductivity. (see Hand out “data sheet 7”)(in addition my students will be using Hach Snap kits for other water quality measurements)
  4. Each group will return to download data. Each group will later create a brief PowerPoint presentation of their data (including:graphs,tables & analysis).
  5. Each group will present power point to class & then discuss their findings and the implications for our water system.

 

ASSESMENT STRATEGIES:

Students will be evaluated on the completeness & credibility of their data via the group’s PowerPoint presentation & discussion.
