EARTH :: METEOROLOGY :: SEASONS OF THE YEAR image seasons of the year Periodic climate changes over the course of a year; they are a function of the Earth’s inclination toward the Sun and its rotation around it. Sun Source of the Earth’s heat. autumnal equinox At the equinoxes, day and night are of equal length; the autumnal (fall) equinox is on September 22 or 23 in the Northern Hemisphere. autumn Season between the autumnal equinox and the winter solstice. winter solstice Shortest day of the year; it falls on December 21 or 22 in the Northern Hemisphere. winter Season between the winter solstice and the vernal equinox. summer Season between the summer solstice and the autumnal equinox. summer solstice Longest day of the year; it falls on June 21 or 22 in the Northern Hemisphere. spring Season between the vernal equinox and the summer solstice. vernal equinox At the equinoxes, day and night are of equal length; the vernal (spring) equinox is on March 20 or 21 in the Northern Hemisphere.
Argumenterande texter Rymden fortsätter På dagens lektion kring rymden så har vi, istället för faktatexter som vi gjort tidigare, jobbat med argumenterande texter. I rymd-temat handlade det den här gången om ÅRSTIDER. Målen för dagen var: Men även då språkligt att eleverna: Vi läste, tittade på bilder och pratade om de olika årstiderna. Utifrån sina kunskaper kring årtiderna fick de sedan skriva på en lapp vilken årstid just jag tycker är den bästa. De fick hjälp av en mall eftersom de bara är andra gången som vi skriver den här texttypen: Målet är såklart att inte behöva använda mallen precis som det står i matrisen, se sista raden på bilden: Sedan fick de skriva sina texter på ett papper där de också skulle måla en bildtext till. Härliga texter blev resultatet!!
Western-backed resolution on Syria doomed? Published time: January 27, 2012 11:25 Edited time: January 28, 2012 08:39 The UN Security Council is due to consider a new resolution on Syria, which demands that the country’s authorities step down. Russia however has stated that the draft offered by the West and the Arab League has no chance of being passed as it is. "The UN Security Council will meet in closed consultations this Friday 3:00 pm in New York to discuss steps to take on the situation in Syria," France's UN mission Twitter page informed. The draft resolution was reportedly proposed by France and supported by the United States, the UK, Portugal, Germany and the Arab countries. According to the Itar-Tass news agency, the new draft will demand that the Syrian regime stop all violence in Syria, withdraw armed forces from inhabited areas and allow peaceful rallies. ‘Fresh draft resolution unacceptable for Russia’ – top official “There are not even such elementary things as a reference to adherence to the UN Charter,” he said.
Could great walls prevent tornadoes forming in the American Midwest? The Great Wall of China was primarily built to keep out nomadic tribes, but a new study suggests constructing great walls in the American Midwest could keep out a different kind of threat – tornadoes. It might sound far-fetched, but a study conducted by Dr. Rongjia Tao from the Department of Physics at Philadelphia's Temple University suggests there is in fact some scientific merit to it. Strategically placed, 1,000 ft (300 m) high great walls could negate the forming of the destructive wind storms in Tornado Alley, and by extension, the destruction they leave in their wake. A piece of land stretching from north to south nestled between the Appalachian and Rocky Mountain ranges, Tornado Alley is home to more than its fair share of violent weather events. According to Tao, the majority of the 811 tornadoes in the US in 2013 occurred in Tornado Alley, a result of its location in the so-called "zone of mixing." So is Tao's idea feasible, or is it mostly just hot air?
Foliegubbar De här foliegubbarna var riktigt roliga att göra. Med relativt enkla medel kan man få till figurer som kan vara utgångspunkt till diskussioner i många olika riktningar. När man gör gubbarna är det lätt att tankarna går till Giacomettis verk. Själva "skulpterandet" - att skapa och få fram olika uttryck kan vara ett annat. Att studera skuggor kan vara ett mål i sig. Gubbarna gör man i helt vanlig aluminiumfolie. Armarna sätts fast genom att en remsa av folie surras ett varv runt kroppen: När man sedan har stommen är det bara att bygga på med folie och forma gubben på det sätt man vill. Sedan är det dags för skuggan. Ett annat alternativ (som jag gjort på gubben med blått papper) är att låta skuggan falla på ett svart papper.

Drugs flushed into the environment could be cause of wildlife decline | Environment Potent pharmaceuticals flushed into the environment via human and animal sewage could be a hidden cause of the global wildlife crisis, according to new research. The scientists warn that worldwide use of the drugs, which are designed to be biologically active at low concentrations, is rising rapidly but that too little is currently known about their effect on the natural world. Studies of the effect of pharmaceutical contamination on wildlife are rare but new work published on Monday reveals that an anti-depressant reduces feeding in starlings and that a contraceptive drug slashes fish populations in lakes. She said: “Given that populations of many species living in human-altered landscapes are declining for reasons that cannot be fully explained, we believe that it is time to explore emerging challenges,” such as pharmaceutical pollution. Research published in September revealed half of the planet’s wild animals had been wiped out in the last 40 years.
Four Seasons Tree Craft With Template - Easy Peasy and Fun We have a wonderful four seasons tree craft template to share with you, this one can fold nicely into a 4 seasons book or you can assemble it together to stand on it’s own. Print our template, there are more versions, and have the kids get creative with their seasons. *this post contains affiliate links* We thought a nice little four seasons tree craft would be a nice addition to exploring and learning about the seasons of the year. This can be a fun four seasons craft for kindergarten, as well as for preschoolers although assistance from parent or teachers will be needed. There are many ways the kids can decorate this project, and there certainly is no need to limit yourself to markers, crayons or pens!

In Kabul, Afghan police sympathize with protesters angry over Koran burning “Afghans and the world’s Muslims should rise against the foreigners. We have no patience left,” said one police officer in central Kabul, who has worked at the same checkpoint since he joined the force seven months ago. He looked at his colleague, who stood next to him, nodding. “We both will attack the foreign military people.” Police officers interviewed at four posts in the Afghan capital voiced the anti-American sentiments on Thursday, the same day that two U.S. troops in eastern Afghanistan were fatally shot by a man wearing an Afghan army uniform. The killings were the latest apparent incident of fratricide aimed at Americans within a nominally united U.S. In the wake of the Koran burning that came to light Tuesday at the largest U.S. military base in Afghanistan, some uniformed Afghan officers have worked tirelessly to keep the peace through three days of demonstrations and riots. U.S. apologies dismissed With tensions still high, however, the U.S. Anger within Bagram base
Overview | National Climate Assessment Climate change, once considered an issue for a distant future, has moved firmly into the present. Corn producers in Iowa, oyster growers in Washington State, and maple syrup producers in Vermont are all observing climate-related changes that are outside of recent experience. So, too, are coastal planners in Florida, water managers in the arid Southwest, city dwellers from Phoenix to New York, and Native Peoples on tribal lands from Louisiana to Alaska. This National Climate Assessment concludes that the evidence of human-induced climate change continues to strengthen and that impacts are increasing across the country. Americans are noticing changes all around them. ©Ted Wood Photography Other changes are even more dramatic. Scientists who study climate change confirm that these observations are consistent with significant changes in Earth’s climatic trends. ©Bill Miles/Mint Images/Corbis Over recent decades, climate science has advanced significantly. ©iStockPhoto.com/shotbydave
