How fast do materials weather?
In the activities described on this website, instructors giving a lecture on weathering ask students to calculate weathering rates from tombstone weathering data from urban and rural settings. The Starting Point site includes downloadable teaching materials, information on learning goals and context for the exercise, and links to useful resources and references.
Inside the Salt II Delegation
Edward L. Rowny was the Joint Chiefs of Staff representative to the Strategic Arms Limitation Talks (SALT) from 1972 to 1979. From 1981 to 1984, during U.S. president Ronald Reagan's administration, he was chief negotiator for the Strategic Arms Reduction Talks (START). In this video segment, Rowny explores Soviet and American negotiating tactics and proposals. He also shares his frustration with U.S. concessions, process, and misconceptions of Soviet thinking, all of which ultimately led to his
Mars Exploration and Geology Animations
This collection includes QuickTime, MPEG-1, and GIF animations and interactive images of Martian exploration and geology. These visualizations illustrate Mars' surface geology and historical and current water presence and display information from the Spirit, Opportunity, Pathfinder, and Sojourner rovers and landers. Many of the visualizations have long download times, but are well worth your patience. These resources are suitable for use in lectures, labs, or other teaching activities.
This site features Flash and QuickTime animations related to groundwater. They contrast the permeability of gravel, sand, silt, and clay, as well as the speed of groundwater movement in rivers, lakes, and aquifers. They also outline the hydrologic cycle, discussing infiltration, percolation, and the water table, exhibit groundwater overdraft and the resulting formation of a cone of depression, and show how groundwater entering fractured bedrock can become superheated and pushed to the surface, e

Peace Is Hard Work
In this lesson, students will create their own lists of what they consider to be the characteristics of a successful peacemaker. They will then research two peacemakers - Jody Williams and Desmond Tutu - and consider how each laureate might take action to end a specific conflict that is happening at the present time.
Modeling Your Water Balance
The purpose of this resource is to model a soil's water storage over a year. Students will model the changes in soil water storage over a year.
Conversations with Berkeley Faculty: Nancy Scheper-Hughes (12/14/99)

Tardigrades: Bears of the Moss
This online PowerPoint presentation is dedicated to the phylum Tardigrada. It discusses distinguishing characteristics of Tardigrades (also known as water bears), their relationship to arthropods and nematodes, internal structures, life stages, cryptobiosis, research opportunities, classification, identification, habitat, distribution, ease of study in the lab, and more. Each slide contains illustrations and descriptions of the microscopic animal.
Tardigrada (Water Bears)
This reference page offers a brief description of Tardigrades, also known as water bears. It includes information about their physical appearance, an explanation of their name, likely habitats, internal organs and other distinguishing features, and a few images. A diagram of a common tardigrade, Macrobiotus macronyx, is also provided via an internal link.
Water Quality For Freshwater Organisms
This website features a field activity that demonstrates the effect of water temperature on the solubility of dissolved oxygen and how it relates to the gill beat rate of fish. The activity uses the Winkler method to measure dissolved oxygen.
The purpose of this resource is to measure the nitrate-nitrogen of water. Students will use a nitrate kit to measure the nitrate-nitrogen in the water at their hydrology site. The exact procedure depends on the instructions in the nitrate kit used.
The purpose of this resource is to measure the pH of water. Students use either a pH meter or pH paper to measure the pH. If using the pH meter, the meter needs to be calibrated with buffer solutions that have pH values of 4, 7, and 10.
Water Temperature Protocol
The purpose of this resource is to measure the temperature of a water sample. Students use an alcohol-filled thermometer or meter to measure the temperature of water. The meter requires calibration before use; the accuracy of the thermometer needs to be checked before use.
From Mud Pies to Bricks
The purpose of this resource is to introduce the different particle sizes of soils and the properties which each contributes to the soil character. Students make mud pies by adding water to the various soil components, letting them dry and observing the pie's characteristics. Students sift soil to remove organic materials and pebbles. They then sift the soil with smaller meshed sieves to separate clay and sand. Students make mud pies by adding water to the various soil components, letting them d
Soils as Sponges: How Much Water Does Soil Hold?
The purpose of this resource is to introduce students to gravemetric measurements - calculating the amount of water in a soil sample or other substance by weighting it before and after drying.
Your Regional to Global Connection
The purpose of this resource is to identify specifically how one's own region is connected with others, and to discover the interconnected nature of the Earth's regions as systems. Students brainstorm about the nature of connections between their region and others, across oceans and on different continents. On a black-line map of the world, they trace possible pathways of water and wind currents from their part of the continent to other continents, and identify what the wind and water carry. The
Diagramming the Study Site for Others
The purpose of this resource is to develop the best possible representation of the study site as a system. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.
Seasonal Change on Land and Water
The purpose of this resource is to further students' understanding of the causes of seasonal change using visualizations to compare the effects of incoming solar energy in the two hemispheres. The class reviews global visualizations of incoming sunlight and surface temperature and discusses seasonal change. Students use the visualizations to support inquiry on the differences in seasonal change in the Northern and Southern Hemispheres, culminating in an evidence-based argument about why one hemi
