On Friday, which was when the event took place, i wasn't there. Since i didn't know what happened, i asked some other people. Other students said that they used their  pin-hole camera and went to a dark room with red lamps since the photos they were going to take would get ruined by regular light. They then cut photo paper and put it into the back of the camera. After, they would seal up the cameras and then turn on the main lights. They went outside and held the camera for 15 seconds on the object they chose for the picture. Then they went back inside, turned of the main lights, took out the paper and put it where the other ones were stored, which was a bag. 

 Plasmas are a lot like gases, but the atoms are different because they are made up of free electrons and ions of the element. An example of a plasma are  The Northern Lights. More common examples are fluorescent light bulbs or neon signs. Both have gas inside them, and when turned on, the electricity runs through and charges up the gas which creates a glow. The type of gas effects what type of colour the glow is. Lightning is one of the nicest types if plasma. The bolts of lighting are hotter than the suns surface. Lightning all starts with the water cycle.  Lighting is still a wonder that scientists are still trying to figure out but the do know that the water cycle is a big part of it. 

In this story, on April 22nd. 2009, Earth passed through comet dust which makes the annual Lyrid meteor shower. This event happened in the morining, and this is when Venus dissapeared from the sky. The reason for this is the Comet Thatcher. Venus dissapears behind thh rim of the moon making it look likes it gone because of the comet and dust.
