Britain was so alarmed by UFO sightings 20 years ago that they breifed ministers
These shocking truths were released on Monday by the National Archives as part of seven files that were recorded from 1989 to 1993. "Such stories are not normally drawn to the attention of ministers," an official noted in a memo included in the file. "On this occasion, however, the MoD has been provided with six photographic negatives of an alleged UFO by the Scottish Daily Record and has been asked for comments almost certainly for inclusion in a forthcoming story." Among the other files released were details of an anonymous female dog walker who said she met an alien who claimed extraterrestrial life was behind crop circles. The woman, who telephoned the Royal Air Force to relay her experience, said the incident happened on November 20, 1989, while she was walking her dog on a sports field. She said she was approached by a man who spoke with a "Scandanavian-type accent" dressed in a brown garment that resembled a flying suit who told her that the purpose of the alien visit was friendly. Britain's ministry of defence was handed negatives of photographs - showing a large diamond-shaped object hanging in mid-air for around 10 minutes before ascending upwards at high speed - taken on August 4, 1990, by two members of the public.

What did the Romans contribute to society?
After the fall of the Roman empire, it took a thousand years for Europe to start flourishing again. F0r 1000 years, there were almost no art and literature in Europe and Europe entered what was called the Middle Ages, or Dark Ages. The Roman empire provided a form of stability and protection for Europe. This meant that during the Roman empire, Europe understood what was the position of everyone and had stability. Everyone understood what their job was and what was expected of them. They knew that they had to give a certain amount of their crops to the Romans and that they had a set of laws that they had to follow or be punished. The Romans also provided protection for Europe. The romans also ensured that none of the barbaric tribes attacked any of the towns and cities that were under their control. The barbaric tribes knew that they would be massacred if they dared attack the cities. After the fall of the roman empire all of this changed. Towns and cities were no longer protected by the soldiers and were continuously pillaged by rogue knights and mercenaries. Europe also did not have any of form of stability and it was a free for all. It was impossible to travel through trading routes without being attacked by bandits. People could kill each other for no reason and get away with it. It took 400 years for Europe to finally get a form of stability back and stop people from being continuously robbed.

Nitrogen Passport Activity
Today we did a Nitrogen Passport Activity in science class. We had to go around to different stations and then start to try and see what cycle we would take. Well not everyone went in the same order because everyone started at different stations and rolled the dice with different numbers. This means that each person follows a different cycle and a different path. The station I started at was animals waste. When looking at the results of this experiment I can tell that cycles repeat itself. The cycle I went through repeated itself halfway, which shows that I took the same path again. This explains why cycles are called cycles. Like the wheels on a bicycle, a cycle always repeats itself as long as there is no interference from other sources. I noticed however that the stations surface water and ocean were usually crowded. This means that most of the nitrogen passes through either the ocean or the surface water or both. This could be due to the fact that rain usually has nitrogen particles trapped inside of it. The nitrogen particles were most of the time transported by water or liquids. Since the ocean and surface water are the biggest sources of water and liquid around, I assume that most of the nitrogen ends up there. I think that the point of the activity was to understand the different ways nitrogen can be transported from one place to another. The nitrogen can be transported by many ways but mainly through water as that is the most abundant source on the planet with 70% of the planet being covered by water. Water also has its own cycle which means that the nitrogen can be transported over long distances in rain clouds.
