This free electrical engineering/technology textbook provides a series of chapters covering electricity and electronics. The information provided is great for students, makers, and professionals who are looking for an application-centric coverage of this field.

This is a writing assignment on the topic of environmental justice for a philosophy-oriented "Philosophy and the Environment" course. It provides somewhat realist scenarios for students to demonstrate their understanding of several theories and practices emerging from environmental ethical issues including race, class, gender, indigenous peoples, and international law and economics.

Students explore Hooke's law while working in small groups at their lab benches. They collect displacement data for springs with unknown spring constants, k, by adding various masses of known weight. After exploring Hooke's law and answering a series of application questions, students apply their new understanding to explore a tissue of known surface area. Students then use the necessary relationships to depict a cancerous tumor amidst normal tissue by creating a graph in Microsoft Excel.

In this jigsaw-method activity on subduction zone volcanism, students apply lessons learned from four historic eruptions to the volcanic hazards associated with Mt. Rainier in the Pacific Northwest.

A series of 6 Excel-based projects on the mathematics of biodiversity for basic college math classes and developmental math classes. Students learn about the structure of biodiversity, the application of many basic data analysis skills, and the use of Excel for analysis and data presentation.

Este libro está dirigido, principalmente, a Estudiantes y Docentes que quieren aprender a programar como forma de fortalecer sus capacidades cognoscitivas y así obtener un beneficio adicional de su computador para lograr un mejor provecho de sus estudios. Dada la orientación del libro respecto a programar para resolver problemas asociados a las Ciencias e Ingenierías, el requisito mínimo de matemáticas que hemos elegido para presentar el contenido del mismo se cubre, normalmente, en el tercer año del bachillerato. No obstante, el requisito no es obligatorio para leer el libro en su totalidad y adquirir los conocimientos de programación obviando el contenido matemático.

In this activity, students construct their own rocket-powered boat called an "aqua-thruster." These aqua-thrusters will be made from a film canister and will use carbon dioxide gas produced from a chemical reaction between an antacid tablet and water to propel it. Students observe the effect that surface area of this simulated solid rocket fuel has on thrust.

In this video Jonathan visits the New England Aquarium as a volunteer aquarist for a day to learn what it takes to care for thousands of fish in dozens of exhibits, up to the massive 200,000 gallon Giant Ocean Tank (GOT). What he finds is an eye opener‰ŰÓit‰ŰŞs not all fun and games. Maintaining an aquarium is serious work. But it does have its benefits, as Jonathan discovers while diving in the GOT and feeding the sharks. This segment won a New England Emmy Award! Please see the accompanying study guide for educational objectives and discussion points.

This short video from NASA discusses the role that salinity plays in Earth's climate and ocean circulation, focusing on the observations of the Aquarius satellite.

The goal of this experiment is to measure the specific storage Ss of a balloon, which simulates aquifer elasticity. The experiment is designed to give observational meaning to the variable, increment of fluid content, and the influence of the state of stress on the specific storage. Increment of fluid content is the poroelastic variable defined as the amount of water added to storage per unit bulk volume. It is analogous to quantity of heat added to a unit volume of a material. Specific storage can then be expressed rigorously as the ratio of increment of fluid content divided by the change in head with specified external stress or strain conditions on the REV.

This page offers 186 different children's stories written in Arabic. Topics range from scientific matters such as how to build a telescope to literature and folktales, including Indian folktales. Stories must be viewed using Java and users must click on the link to view the resource and its title. Many contain images and other illustrations. The intended age level of the reader varies from story to story.

This Western Mining History database uses Mineral Resources Data System to list known Colorado historical mines by county. Each county site has links to the known mines within its borders. Some are known and named, others are unnamed. Mines should be assumed to be on private property unless other research is conducted. Data provided for each mine site include: Name, State, County, Elevation, Primary Mineral Mined, Latitude and Longitude and a link to Google Maps. Photos are provided where available. Additional information for some Mines are satellite photos, and ownership, business and historical records. Mining History is an historical site that provides information on mining, mining towns, the gold and silver rush, and Photos and maps of the western United States. This is a great database for student historical research or data and statistics classes. Consider becoming a member or making a donation to help further the work of the site.

Living Atlas Indicators of the Planet provide the user with up-to-date data, maps, graphs, charts, animation and other visuals to explore the science of climate and environmental change. 18 indicators from Air Quality to Women in Parliament can be explored.

Archeology: Stop 13 Museum of the West Virtual Tour. Watch this short video to learn about a Museum of the West exhibit or collection to preview your field trip or for a virtual field trip if you are unable to attend in person. The Museum of the West is part of the Museums of Westen Colorado. Join archaeologist, Phil Born, as he explains what an archaeologist does and shows us the BLM archaeology collections at Museum of the West

Students are introduced to Pascal's law, Archimedes' principle and Bernoulli's principle. Fundamental definitions, equations, practice problems and engineering applications are supplied. A PowerPoint® presentation, practice problems and grading rubric are provided.

Spreadsheets across the Curriculum Activity. Student build spreadsheets that allow them to estimate pi using the same iterative process as Archimedes.

Students explore the interface between architecture and engineering. In the associated hands-on activity, students act as both architects and engineers by designing and building a small parking garage.
