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.

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. Some people argue that Canberra is one of the only places in the country that can genuinely claim to experience all four seasons.
Summer and Winter The boundary AB between sunlight and shadow--between day and night--is always perpendicular to the Earth-Sun line, as it was in the example shown at the beginning. But because of the tilted axis, as each point on Earth is carried on its daily trip around the rotating Earth, the part of the trip spent in daylight (unshaded part of the drawing) and in the shadow (shaded) are usually not equal. North of the equator, day is longer than night, and when we get close enough to the north pole, there is no night at all. The Sun is then always above the horizon and it just makes a 360-degree circuit around it. That part of Earth enjoys summer .
Seasons on Other Planets Each planet in the solar system has seasons. Earth has four seasons.
Grasslands go by many names. In the U.S. Midwest, they're known as prairies. In South America, they're called pampas. Central Eurasian grasslands are referred to as steppes, while in Africa they're named savannas. What they all have in common is grass as their naturally dominant vegetation.
Your Mission Become a season sleuth. Learn the long and short of the changing of the seasons, then test your knowledge with our cosmic map. Briefing In most regions of the Earth, the cycle of the year can be separated into four distinct seasons: summer, autumn, winter, and spring. Each season brings with it distinct changes in weather, temperatures, and length of daylight.
