- Abstract: CK-12 users should treat this FlexBook as an online textbook for Earth Science courses. This FlexBook underwent a thorough review conducted by practicing teachers, domain experts, copyeditors, and technical editors. It can be used in its current form, "flexed" (customized), and/or printed by the user. CK-12 supports feedback on all of its FlexBooks so that they can be continually improved and updated, while remaining aligned with state standards and curriculum guidelines.
This digital textbook was reviewed for its alignment with California content standards.

- Abstract: The research-based Arctic Climate Modeling Program (ACMP) is funded by NSF ITEST. Curriculum based resources were designed with input from 21 scientists from the University of Alaska Fairbanks Geophysical Institute. Resources include K-12 inquiry-based classroom lessons, a student network for observing arctic weather, digital lectures, and an interactive multimedia learning system (on DVD).

- Abstract: Through discussion and hands-on experimentation, students learn about the geological (ancient) carbon cycle. They investigate the role of dinosaurs in the carbon cycle and the eventual storage of carbon in the form of chalk. Students discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth. Finally, they may extend their knowledge to the concept of global warming and how engineers are working to understand the carbon cycle and reduce harmful CO2 emissions.

- Abstract: This lesson introduces and describes the main types of erosion (i.e., chemical, water, wind, glacier and temperature). Students learn examples of each type of erosion and discuss how erosion changes the surface of the Earth. Students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause. Figure 1 is an excellent illustration of water erosion.

- Abstract: Young students are introduced to the complex systems of the Earth through numerous lessons on the Earth's natural resources, processes, weather, climate and landforms. Key earth science topics include rocks, soils and minerals, water and natural resources, weather patterns and climatic regions, wind, erosion, landforms, and the harvesting of fossil fuels all presented from an engineering point-of-view. (See the Unit Overview section for a list of topics by lesson.) Through many hands-on activities, students build and test sand castles for construction strength, measure snow melt as a potential water source, use colored ice cubes and salt water to learn about ocean currents, make 3-D water catchment basins, make surface tension/surfactant-powered paper boats, build and use wind vanes, build and test model wind turbines, model and observe five types of erosion, model acid rain using chalk and kitchen supplies, build transportation systems across their own 3-D model landscapes, take core samples from a clay model of the Earth's crust, read and create graphs and charts as they learn about international oil production and consumption, act as engineers by specifying the power plants to build for communities, given scenarios with budgets, energy needs and environmental impacts. They learn the steps of the engineering design process as they hypothesize ways engineers might obtain water for communities facing water crises.

- Abstract: University of College London hosts a site of notation and reference material on math skills in the context of geoscience. These exercises provide realistic geologic scenarios and work through examples, with notation on the math used to solve them. Examples include using trigonometry to find the true width of strata, logarithms to understand the Richter scale, and vectors to find plate velocities at a triple junction. Relevant vocabulary is linked to a glossary of mathematical terms. Many of the modules link to a MathHelp page for explanation of techniques used, and then come back to the geologic scenario to finish the problem. This resource is part of the Teaching Quantitative Skills in the Geosciences collection. http://serc.carleton.edu/quantskills/

- Abstract: This hands-on activity explores five different forms of erosion (chemical, water, wind, glacier and temperature). Students rotate through stations and model each type of erosion on rocks, soils and minerals. The students record their observations and discuss the effects of erosion on the Earth's landscape. Students learn about how engineers are involved in the protection of landscapes and structures from erosion. Math problems are included to help students think about the effects of erosion in real-world scenarios.

- Abstract: The aerial video and still photography assembled here allows users to see "before" and "after" imagery of the impacts of coastal storms. Oblique images are available for storms from Hurricane Ivan in 2004 to Hurricane Fran in 1996. Each set of images is accompanied by a brief description, and some LIDAR imagery is available Links to other related sites are also included.

- Abstract: Students learn about landslides, discovering that there are different types of landslides that occur at different speeds from very slow to very quick. All landslides are the result of gravity, friction and the materials involved. Both natural and human-made factors contribute to landslides. Students learn what makes landslides dangerous and what engineers are doing to prevent and avoid landslides.

- Abstract: This interactive feature story is part of Science Bulletins, an innovative online and exhibition program that offers the public a window into the excitement of scientific discovery. Published in April 2004, this AstroBulletin examines the discovery of firm evidence that water once flowed on Mars -- perhaps enough water to harbor life.
