Air and Space Museum

     Last week, on Thursday we went on a field trip to the Air and Space Museum. We met at the Smithsonian Metro station and walked toward the museum. The museum was well organized with high security where we as well as our bags were checked properly.

    In the morning time the museum was not crowded so that we could see things clearly. We followed our teacher's instructions and got to know about the museum. We went inside the room about science, pressure, speed, water, air and vacuums. This helped us to know how airplanes are built.

    In the picture on the left , you can see that water does not compress easily so that the speed of the water increases in the narrow space, in contrast the speed of the water flow slows down on the broad part.

 In the picture on the right, the continuous air pressure from the blower flows around the ball and forms low pressure around the ball. Due to the low pressure, the ball starts to fall however the high surrounding pressure shoves it back and that keeps the ball up without falling.

   

     As we were walking around we found one great instructor who was really nice. His name was Mark Goldberg. He took us step by step to make us understand about the creation from small to giant airplane and rockets. His English was clear with audible sound which made it easier to understand.

 The creators were the Wright brothers, who were bike mechanics. Their strong will and dedication led to the invention of the airplane.

   
 I was glad to see all the real airplanes, from the invention until today. I had lot of fun when I got inside the airplane and saw how they were built in the past.
