The Floating Lithosphere - Isostacy
This activity lays the mathematical underpinning for studying isostasy in the earth. Students numerically and then analytically determine the relations governing the depth of compensation in a variety of situations including a block of ice floating in water. They recreate spreadsheets shown in a Powerpoint module with formulas that answer various pieces of the overall question. This module is the first in a set of three exploring isostasy, and was designed for an undergraduate class where studen
Winter Field Lab: Pond Hydrology
This field activity may be implemented during late winter or early spring when things have not quite thawed. From a frozen pond, students collect bathymetric data, measure water temperature and conductivity, locate ground-water inputs, and extract a sediment core. Back in the lab, they make hand and computer-contoured bathymetric maps, temperature and conductivity cross-sections, and run visual-core log, loss-on-ignition, and magnetic susceptibility tests. Then they draw conclusions about water
Winter Field Lab: Snow Hydrology
This field activity may be implemented during late winter or early spring when things have not quite thawed. Students collect their own data from a snowpack, including measuring water equivalent, identifying types of snow metamorphism, finding evidence of precipitation patterns, and judging possible snowpack hazards. Back in the lab, students evaluate their data, draw conclusions, and make a report. This activity is designed for upper-level undergraduate and graduate-level geohydrology courses.
Angle of Repose
In this activity, students explore how different sediment properties influence slope stability. They make piles of sediments with varied grain size, angularity, and water content and measure the maximum slope at which the grains are stable. The results are then used to examine the nature, frequency, timing, and causes of landslide events in Seattle. Learning goals, context for use, teaching tips, materials, assessment tips and related resources are provided.
USGS Techniques of Water-Resources Investigations: Frequency Curves
This 21-page pdf file is Book 4, Chapter A2 of a series of manuals on techniques and procedures for planning and executing specialized work in water-resources investigations. It describes procedures for preparing frequency curves from samples of hydrologic data. It also discusses the theory of frequency curves, compares advantages of graphical and mathematical fitting, suggests methods of describing graphically defined frequency curves analytically, and emphasizes the correct interpretations of
Water Quality Acquisition
In this activity, students visit two sites to practice their field water sample collection and water quality assessment skills. They use a vertical well-water sampler and downhole water quality probes to measure groundwater conductivity, pH, and temperature at different depths in a landfill. Collected water conductivity data is contoured to map the distribution of a contaminant plume. Students then study acid mine drainage by using water quality meters to compare pH and conductivity values up an
Analysis of an Aquifer Test at St. Paul Island, Pribilof Islands, Alaska
This 30-page PDF was prepared by the Alaska Department of Natural Resources and provides detailed information about the water supply available on St. Paul Islands. The site presents the results of an aquifer test and estimates potential yield from current wells. Tables, diagrams and well logs are included.
Drinking Water Treatment 1 - Technology
The course provides the technological background of treatment processes applied for production of drinking water. Treatment processes are demonstrated with laboratory experiments.
Public Hygiene and Epidemiology
A framework of public hygiene and epidemiology is given. Human pathology related to water and sanitation is dealt with, as well as the relation between health and society and environment.
Pumping Stations and Transport Pipelines
Water transport through pipes, pressure losses, (pressure) network design and building, pump selection, pumping stations, power supply, quantitative reliability, operation and maintenance.
Technology Dynamics and Transition Management
This version of the subject Technology Dynamics and Transition Management was taught in co-operation with the Harbin Institute of Technology in China. At the heart of this module lies a model of technology development from a social perspective, which will be applied to water problems in present-day China.
Water management in Urban Areas
Master course on design and planning of the urban water management system. It deals with fluxes and processes in water and soil. Furthermore, aspects of water management policy development are discussed.
Ants Create a Lifeboat in the Amazon Jungle - BBC Wildlife
This video is suitable for older elementary, middle school, and high school students and focuses on a colony of fire ants who create a way to cross water. Amazing! 2:52

Introduction to Minitab
This laboratory introduces students to the basics of the Minitab software. Students make use of a basic example (water consumption and temperature) to introduce students to manipulation of data, calculation of descriptive statistics, and creation of histograms.
Star Library: Which Paper Towel is More Absorbent?
This group activity focuses on conducting an experiment to determine which of two brands of paper towels are more absorbent by measuring the amount of water absorbed. A two-sample t-test can be used to analyze the data, or simple graphics and descriptive statistics can be used as an exploratory analysis. ...
The Kankapot Creek Coast Guard: Public service through water quality monitoring of a stressed stream
The Biology Department at the University of Wisconsin -- Fox Valley is carrying out a long-term project in which students gather water quality data on a nearby impaired stream. These data will eventually be used to help formulate a restoration plan for the stream. This exercise follows the procedures our students use to assess stream habitat quality, chemical and physical parameters, and benthic macroinvertebrate diversity and pollution tolerance. Data collection is completed in the field using
The Use of the Biotic Index as an Indication of Water Quality
This is a field/laboratory exercise involving the collection, identification, and use of aquatic insects to estimate the water quality of lotic stream ecosystems. Aspects of this laboratory are appropriate for an introductory biology course, an extended student project, or a detailed laboratory exercise ...
