In this video, NOAA's Deke Arndt, Chief of the Climate Monitoring Branch at the National Climatic Data Center, recaps the temperature and precipitation data for the continental US in summer 2012. It describes how these conditions have led to drought and reduced crop yields.

In this learning activity students learn how to and practice having conversations about climate change with adults or peers. The activity is based on psychological and social science research.

In partnership with the National Science Digital Library and Apple, NCAR and UCAR offer podcasts that provide a brief and accessible overview on climate and climate change. These podcasts, short 5-8 minute videos you can download on your computer or iPod, are a part of the NSDL on iTunes U collection.

This activity is a field investigation where students will observe, discuss, and gather evidence on how environmental changes affect animals that live in that habitat.

A civilian propaganda poster showing boys and girls raising sheep, above them are sheep walking along a roadway that leads to the top of the poster where a battle is underway. Caption continues: Write to-day for full information to your County Agent or Club Leader or State Director of Extension State Agricultural College.

This is a two part journaling activity prior to an existing week long biology field lab. The journaling activities described here have been added to the beginning of the Pond Study Lab to enhance student learning of observation and quality journaling skills.

The purpose of this resource is to observe plant green-down and report greendown data to help validate estimates of the end of the plant growing season. Students monitor the change in color of selected leaves of trees, shrubs or grasses.

This video segment from Nature takes viewers to a road race in Death Valley.

This video segment from NatureScene features the area of the Congaree Swamp where the high ground and the flood plain meet. Learn how a few feet of difference in elevation on a floodplain can yield drastic changes in what youŰ__Ű__ŒŒÇll find living there.

This poster, viewable online, highlights some of the impacts of a global-average temperature rise of 4 degrees C above the pre-industrial age climate.

This animation illustrates how the hardiness zones for plants have changed between 1990 and 2006 based data from 5,000 National Climatic Data Center cooperative stations across the continental United States.

In this field investigation, students will identify and determine the population size of snails in an aquatic environment.

In this ecology investigation, students will build and place rock baskets to collect benthic macroinvertebrates in a local waterway. They will observe and identify their macroinvertebrates and use the data to determine the pollution tolerance index for various areas of a river.

In this media-rich lesson, students learn how global warming is changing the Alaskan environment and examine the consequences of climate change on the region's human and wildlife inhabitants.

Laboratory Manual-SPPU-TYMicrobiology-MB359This laboratory manual is made as teaching and learning resource in microbiology laboratory especially for the third year students studying practicals in Fermentation and Agriculture microbiology. Although meticulously drafted(Ver.1.1) but not perfect, we want to make it near to perfect.

Energy access plays a vital role in reducing undernourishment and improving food security. It boosts agricultural productivity, enhances food quality, reduces losses, and enables transportation. However, addressing factors like political instability and poor policies is crucial alongside increasing energy use.

Some bird species appear to respond to extreme weather changes in their native habitat by moving to more hospitable environments. This article discusses the role of NASA satellites, along with field and citizen scientists, in studying that movement. The article also includes an activity on constructing a bird feeder. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

This movie provides an 18-minute introduction to how NASA is observing our ever-changing planet. On the The Dynamic Earth DVD Web page you can download the video as an iPod or iPhone version, as well as an AppleTV/Full resolution version, and access a glossary and links to related Web sites.

La rápida expansión de la frontera agrícola como consecuencia desmesurada de la deforestación y cambios antropogénicos a nivel mundial, es un tema de preocupación por la comunidad científica internacional. Además, frente a una lucha contra el cambio climático por efecto de la ganadería, una de las principales estrategias para la mitigación de gases de efecto invernadero, lo constituyen alternativas sostenibles si uso de productos con alta huella de carbono, revalorizando, además, los recursos locales. En el caso de la zona norte de Ecuador, a pesar de los limitados atributos respecto a gradiente de fertilidad de los suelos, la cría de ganado ya sea de leche y/o doble propósito representa uno de los eslabones más fuertes dentro de la economía de las familias. Por lo tanto, es menester investigar alternativas de producción que nos permitan conservar los recursos naturales dada la fragilidad de estos ecosistemas megadiversos. Mediante este libro se plasma que el uso de sistemas ganaderos convencionales, degradan los recursos naturales con mermas significativas de la productividad, así como bajo réditos económicos. En consecuencia, la implementación de sistemas silvopastoriles como alternativa tecnológica de fácil instalación, es sin duda el camino para alcanzar sistemas ganaderos más eficientes, amigables con el medio ambiente, diversificando además los ingresos económicos de la población.

In this video segment from NatureScene, observe dragonflies and mayflies near Cedar Creek at Congaree Swamp National Park.
