Materials presented here outline basic concepts related to groundwater, answering questions like "What is groundwater?" and "What is an aquifer?" More detailed topics include groundwater quality, sources of contamination, engineering problems presented by groundwater, and safeguards to the groundwater supply. A bibliography and links to other water-related sites are included. A French translation ... Full description.

This slide show provides basic information on the three major rock types and the rock cycle. Diagrams of the rock cycle explain the processes and changes that connect the three rock types and illustrate how one type can be changed into another. Each of the three types (sedimentary, igneous, metamorphic) are described and illustrated with photographs. Addresses for websites with additional information ... Full description.

This lesson has students observe and quantify their household and vehicle energy consumption; explain the relationship between energy consumption, energy production, and its influences on the greenhouse effect and global climate change; and suggest adaptation and mitigation strategies as to how he or she could reduce household and vehicle energy consumption in order to minimize carbon dioxide emissions. ...

In this activity, students will build a model to simulate parts of the water cycle. They will be able to recognize and explain the essential elements of the water cycle. From this information, they will appreciate that scale models can be an important tool to use in understanding global processes. The student guide provides an overall description of the activity, a list of materials, the procedure, ... Full description.

In this activity, students will investigate the weathering of rocks by chemical processes. They will use effervescent cleansing tablets as a model for rock, and vary surface area, temperature, and acidity to see how rapidly the "rock" dissolves. This investigation will help them understand three of the factors that affect the rate of chemical weathering and develop better understanding of how to design ... Full description.
