This lab activity investigates porosity, permeability and relationship. Students will understand porosity and how gases/liquids can move through permeable materials (permeability). Also, students will repeat a valuable scientific experiment performed on the International Trans-Antarctic Scientific expedition by expedition members and Dr. Mary Albert (of the USA Cold Regions Research and Engineering ...

This site uses Virtual Reality field trips in the Alvin submarine to the East Pacific Rise to explore hydrothermal vents. The education activites focus on 4 activities: Exploration, Observing (actual video from the seafloor), Mapping, and Collecting a Water Sample. Teaching materials for each of the explorations have been provided, each with two levels of assessment (basic and advanced). Full description.

This resource provides information on isostasy and the effects of glaciation on the Earth's lithosphere. The descriptions and scientific illustrations demonstrate how glaciers and the growth of continental ice sheets can put pressure on the Earth's crust, causing local and regional-scale depressions of the lithosphere. As the ice thins or decays, this pressure is released, resulting in an isostatic ... Full description.

The Deep Biosphere Laboratory at Goteborg University consists of about 10 people whose unifying interest is in microbial life in underground and sub-seafloor environments. Visitors to the site can access summaries of research projects, personnel information, and links to publications on the topic of underground and sub-seafloor microbes. Research topics include microbes in deep Swedish and Finnish ... Full description.

The site contains thousands of images and is searchable by category, continent, country, or keyword. A ... Full description.

Using paper patterns, students are able to construct a model that depicts Karst topography, including typical features such as caves, limestone bedrock, sink holes, and springs. The accompanying Teachers Guide provides extensive background information about the dissolutional processes that form caves. Information is also provided about unique animals found in caves and the importance of understanding ... Full description.

This Oregon State University site offers in-depth information on groundwater including: human impacts, protection, contamination, regulations, agencies, community action, and community stewardship. Although some information, such as how the geology of Oregon affects groundwater, is specific to that state much of the information is transferable to other locations. Full description.

These resources include sections on the latest quakes, science project ideas, puzzles and games, online activities, a glossary, and cool earthquake facts. In addition, there is an Ask A Geologist section, and earthquake FAQs. One link leads to a teacher page with grade level topics and educational materials. Full description.

Researchers have identified approximately 140 individual impact craters on Earth. These craters probably represent only about 25 percent of those to be found. Assuming an equal rate of impact around the globe, many more craters remain to be discovered, particularly in remote land regions of our planet and in the oceans. This activity uses satellite images of several craters on the earth to study impact ... Full description.
