The Lost Seasons - Features - The Lab - Australian Broadcasting Corporation's Gateway to Science Hundreds of years ago, the seasons in Australia were marked by local events like sharks breeding and wattle flowering. The indigenous people had a good empirical knowledge of their local weather. Today science is finally acknowledging the validity of indigenous weather knowledge. Danny Kingsley reports on the new partnership between ancient wisdom and modern science. Australia is a large continent, with very different weather patterns all over it, yet since European occupation, the 'traditional' view of the weather has been that of the Northern Hemisphere, with four seasons; Spring, Summer, Winter and Autumn. Everywhere else, the weather is localised and different. Of course, those people who have lived in the country for thousands of years take a very different approach to the weather, tied up as it is with food supply, shelter and the land in general.

Switch Zoo - Animal Games dosclics Stellarium Lesson Plans - Seasons: Why It's Essential Grades 9-12 Overview: High school students should have a clear understanding of why the seasons occur and should be able to articulate this concept to others. This lesson reinforces this knowledge by having students review the basics of the seasons and design their own monuments to keep track of and commemorate the seasons. In the process students will review their understanding of the science behind the seasons, learn some theories about Stonehenge, Medicine Wheel, and other monuments, and reflect on their own culture's methods of commemorating the passing of the seasons. Connections to the Curriculum: Geography, earth science, history Connections to the National Geography Standards: Standard 7: "The physical processes that shape the patterns of Earth's surface" Standard 17: "How to apply geography to interpret the past" Time: Two to three hours Materials Required: Computer with Internet access Writing and drawing materials Objectives: Geographic Skills: S u g g e s t e d P r o c e d u r e

Inicio - Tiching Windows to the Universe Grasslands Grasslands go by many names. In the U.S. Midwest, they're known as prairies. In South America, they're called pampas. In fact, most grasslands are located between forests and deserts. There are two different kinds of grasslands: tropical and temperate. Tropical grasslands are warm year round, but usually have a dry and a rainy season. Temperate grasslands, which average between 10 and 30 inches (25 and 75 centimeters) of rain per year, have shorter grasses, sometimes just a few millimeters. The animals that live in temperate grasslands have adapted to the dry, windy conditions. When rainy season arrives, many grasslands become coated with flowers, some of which can survive well into winter with the help of underground storage organs and thick stem bases. No other habitat is as agriculturally useful to humans as grasslands. Fires, both natural and human-caused, are important in maintaining grasslands.
