Average inquiry level: Structured
This groundwater lab is designed for online, asynchronous instruction and uses Google slides (or Powerpoint) so student can use the draw features. Within this lab, students will:
- Evaluate and conclude the seasonal and annual trends of the water table from data monitored groundwater wells;
- Predict and assess the permeability and porosity of different substrates and rocks;
- Create a contour map and cross-section of the water table given data from multiple wells and draw the flow direction of water;
- Predict and communicate the changes of the water table that could occur in response to different water-related scenarios;
- Determine solutions for an area experiencing groundwater problems.
This lab is appropriate for introductory geology courses, for majors or non-majors.
Skills and concepts that students must have mastered
Students should already know:
-Basic rock and sediment types
-How to read and extract information from graphs (although, this is practiced in the lab)
-Basics about contour maps
-Basic background information about groundwater and aquifers
-Vocabulary to describe groundwater systems
How the activity is situated in the course
This is a stand-alone lab activity.
Content/concepts goals for this activity
The concepts that are covered in this lab are: trends in water well data, porosity and permeability of sediments and rocks, groundwater flow and contamination, and groundwater as a resource.
Higher order thinking skills goals for this activity
This lab asks students to perform the following higher order thinking skills: analyzing and forming conclusions from well data, designing an experiment, making and revising predictions, contouring from well data, determining groundwater flow direction, applying knowledge to create a solution.
Other skills goals for this activity
Students are asked to synthesize and write conclusions that can be easily understood by the public.
Description and Teaching Materials
This lab is provided in a powerpoint file, which can be imported into Google slides (Exploring Groundwater lab.pptx). The lab has four parts and asks students to visit a few websites or view videos to gather important information. Links are embedded within the presentation, but if information is no longer available, the supplemental pdf (WellData.pdf) contains well data and the Tucson Water report.
The "Exploring Groundwater information sheet" (.docx) provides basic information about the lab, while the "Exploring Groundwater lab instructor notes" (.docx) provides a detailed explanation and tips for implementing the lab.
A key is provided (KEY Exploring Groundwater.pptx) with responses and a suggested grading rubric.
