What effect does geography have on air quality? Use this model to explore the effect of point-source pollution, geography, and wind on regional air quality.
What causes an area to have poor air quality? Use this model to explore the connections between pollution sources, weather, geography, and air quality. Discover which weather condition causes the development of additional air pollutants. Compare the effects of two different pollution sources, pollution-control devices, and changing weather conditions on the air quality over a city.
Have you ever wondered what defines a gemstone? Or, maybe you have a favorite and want to know how it's formed. No matter what the reason is, this resource was created to help you learn more about gemstones! This resource includes facts about rubies, sapphires, emeralds, tanzanite, opals, and diamonds including where they are formed, how they are formed, colors for each, and more! Then test your new knowledge with a quiz! Student OER: Jessica Brown, Author
Se examina estrategias para optimizar la alimentación de rumiantes mediante el cultivo y manejo de diferentes forrajes en Santo Domingo de los Tsáchilas, Ecuador. En el primer capítulo, se destaca cómo el encalado y la fertilización mejoran el rendimiento del maíz, enfatizando en dosis óptimas de nutrientes. El segundo capítulo aborda la fertilización orgánica del pasto Mombasa bajo sombra de naranja, resaltando la superioridad de la pollinaza en el incremento de rendimiento y calidad del forraje. Los capítulos siguientes se centran en la edad óptima de corte para maximizar la biomasa del pasto Cuba OM-22, el manejo del King Grass como alternativa forrajera para el sector ganadero, y el desarrollo del forraje verde hidropónico de sorgo y maíz a dos densidades de siembra, demostrando que técnicas específicas de manejo y cultivo pueden significativamente influir en la productividad y sostenibilidad de la alimentación rumiante. A través de estos estudios, el libro propone soluciones prácticas y sustentables para mejorar la nutrición de rumiantes en entornos tropicales.
This is a research project for an Environmental Geology class, in which each student selects or is assigned a type of alternative energy to investigate. The project culminates in a 10-15 minute class presentation with accompanying written abstract.

This short film uses graphics to provide an introduction to the physical causes of earthquakes, and to explore how the way we build and manage our cities determines their vulnerability to a seismic strike.
It was created with the UK GCSE and A' Level curricula in mind.
Instructional sequences are more coherent when students investigate compelling natural phenomena (in science) or work on meaningful design problems (in engineering) by engaging in the science and engineering practices. We refer to these phenomena and design problems here as ‘anchors.’Here is a tool to assist in determining if the elements of the anchoring phenomenon are strong or could use some additional thinking. Original works can be found at NextGenStorylines.org

Explore the physics and material science of making stone tools. Educator Nate Salzman walks us through the surprisingly complex science of flintknapping, or the process of turning stone into blades, arrowheads, spear points, axes, jewelry and more. Making tools from stone may be thousands of years old, but required people to think about the properties of the material they were using and the physics of striking the stone to shape it just right.NOTE: These are animations derived from the video "The Science of Knapping" which is linked here and published under its own listing on OER Commons.This resource is part of Jefferson Patterson Park and Museum’s open educational resources project to provide history, ecology, archaeology, and conservation resources related to our 560 acre public park.

The Polar Rock Repository at the Byrd Polar and Climate Research Center offers no-cost Rock Boxes for use by educators in both schools and informal learning environments, such as libraries, scout groups, and Science Olympiad teams. Each box may be borrowed for one month and contains more than 30 representative samples (rocks, minerals, fossils), printed materials for student use (books, descriptions, etc), teacher materials (also available online), and tools to examine the samples. With few exceptions, all of the samples in the boxes were brought back from Antarctica over the past century by U.S. expeditions!
A virtual version of the Rock Box may be viewed here. In addition to 3D models of rock samples, high resolution photographs and descriptions are linked.
O aplicativo GeoSensor é o produto técnico da dissertação de mestrado intitulada: App GeoSensor, Geotecnologias Aplicadas ao Ensino das Ciências Ambientais, apresentada ao Programa de Pós-Graduação em Rede Nacional para Ensino das Ciências Ambientais – Profciamb, núcleo UFPA. O app foi concebido como uma forma de disseminar conhecimentos em Geotecnologias, de maneira didática e acessível, além de fazer paralelo com conhecimentos de disciplinas curriculares, como matemática, física e química, de modo a servir como incentivo ao Ensino de Ciências Ambientais, despertando o interesse dos alunos, utilizando exemplos de aplicações práticas de conceitos vistos em sala de aula, além de possibilitar aos educadores demonstrar as aplicações do conhecimento obtido em sala na vida de todos.
O aplicativo foi desenvolvido tendo como público-alvo discentes e docentes do ensino médio, com possibilidades de aplicação também a partir do ensino fundamental 2, bem como em níveis técnico e superior.
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.

This article and slide show from the New York Times, features several scientists from the University of Alaska, Fairbanks, who study the effects of thawing permafrost in Alaska.
In this laboratory exercise students will have an opportunity to examine the crystal structures, optical properties and health hazards of the common asbestos minerals. The laboratory will reinforce optical microscopic skills that students have learned in mineralogy and show them how mineralogy can be critical to understanding a current public policy issue.
