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:
- Students will become more interested in environmental
issues.
- Students will value the local water system.
- Students will understand problems facing our creek
systems.
SPECIFIC MEASURABLE OBJECTIVES OF THIS LESSON:
- Students will be able to measure water quality using
Xplorer probe ware technology.
- Students will be able to analyze data collected with
probe ware.
- 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:
- Technology does the analysis for you.
- Water quality tests are not related to each other.
- “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.
- Intro/Motivator:Bill Nye Video:”Stream keepers”
- Review Probeware instructions & map testing area.
- 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)
- Each group will return to download data. Each group
will later create a brief PowerPoint presentation of their data
(including:graphs,tables & analysis).
- 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.
