Helium Weather Balloons A weather balloon is a scientific instrument used by meteorologists to measure the activity of the world’s weather. Weather balloons are sent into the air every day‚ all over the world; they are sent up at the same time‚ and they are used to measure a variety of atmospheric pressures‚ temperatures‚ and wind rates. The data collected by weather balloons is saved and transmitted by the radiosonde. Sensors in the radiosonde record data and use a radio transmitter to send

Hot Air Balloon Report Hot air balloons fill up slowly and then rise in the sky. Two important principles of physics: the ideal gas law and Archimedes’ principle are the reasons hot air balloons fly. The mathematical relationship between the volume pressure and the temperature of a gas is called the ideal gas law. When a gas is heated‚ as in a hot air balloon‚ then its volume will increase. However‚ there is a heater located in the balloon’s basket that heats the air inside the balloon and blows

clothes mummy wore. She would be like mummy when she was older. “Sweetie‚ do you want a balloon?” She looked at where her mummy was pointing. An old wrinkly man stood there‚ holding a bunch of balloons of all shapes and sizes and colours. He looked like a garden gnome. She smiled and nodded. Her mummy smiled back‚ her teeth all yellow.

enjambment of “love’s… hate” shows how easily love can change into hatred. The red balloon bursting shows her heart break. Red has traditionally been associated with courage and love in Western culture‚ but in China‚ red is the colour of happiness and good fortune.

The setting is 1950’s Paris‚ France. The main character is a young boy - perhaps seven. And the object of everyone’s desires is the red balloon. Somehow it seems sentient. Somehow it seems friendly. Directed by Albert Lamorisse‚ "The Red Balloon" is a strangely heartwarming short film about how an innocent desire can quickly spiral into a dangerous‚ and often destructive‚ form of envy. Because‚ as the saying goes‚ "if I can’t have it‚ no one can." In one of the early scenes‚ the audience sees the

The song I chose to do my project on is the song 99 Red Balloons‚ by the artist Gabriel Kerner‚ also known as Nena.

This song is representing the fact that the United States and the Soviet Union were caught up in the Cold War and it caused
