Is your school good for the environment?
Being green wasn't easy for Kermit the Frog(a famous cartoon character)—but it is for a growing number of schools around the country.A "green" school is an environmentally friendly building that uses less energy by depending on earth's natural resources for heat,light,and power.Green schools have clean air,a lot of natural light,and renewable power sources.
New studies show that green schools are not only good for the environment,but good for you too!Kids in classrooms with a lot of daylight scored 25 percent higher on reading and math tests than students who studied in rooms with less natural light.Students in schools with more natural light took three to four fewer sick days than students exposed to artificial classroom lighting.The further study found that those students had less dental decay(龋齿)because they were exposed to more of the vitamin D produced by the sun.
The Willow School in N.J. is a school that was built as a green building in 2002.Parts of the building are made wholly from recycled materials.To help trap heat,for example,building workers filled the walls with material from old blue jeans instead of the traditional insulation(绝缘物)made of chemicals.Every classroom has skylights to allow most sunlight,and solar panels(太阳能电池板)line the south end of the building.It uses about 70 percent less energy than a non-green school.This helps the school cut down on high energy costs.
Kate Burke Walsh,head of the Willow School,says,"Sunlight has an impact—you're happier."The clean,natural surroundings help both students and teachers "handle stress and stay relaxed and focused…it's a very calming atmosphere."
Gypsies According to the linguistic and genetic researches, ancestors of the Gypsies left the land of India in the amount that did not go beyond 1,000 people. Today there are about 10 million Gypsies in the world. Some scientists believe that Gypsies were Egyptians. | |
Sumerians Sumerians must be the mysterious people in the ancient world. We know nothing about their origin and nothing about the origin of their language. The Sumerians were rather advanced—they became the first in the Near East to use a wheel, to create an irrigation system and their unique writing. And besides, they were impressively good at maths and astronomy. | |
Maya Some scientists believe that they are connected to legendary atlantes (男像柱), others suppose their ancestors were Egyptians. It's thought that the Maya created an efficient agricultural system and had deep astronomy knowledge. Their calendar was used by other people of Central America. Maya applied the hieroglyphic writing (象形文字) system. Now it seems that the Maya came from nowhere and disappeared nowhere. |
