LI: To find out how many fins you would need on a rocket to help it fly effeciently.
This week we had Tech at Tamaki College. We were learning about Rocket Science with Ms Sharma and Mr Dunn. We started off by identifying the main features and attributes of how a rocket can fly. With Mr Dunn we learnt that weight and mass are two different things, if we were to go to mars our mass would stay the same but the weight would change. This is due to the amount of force in space and the planets.
The reason we use rockets are to send cargo through space and stop bombs from other countries attacking a certain area. Due to gravity when the rocket flies off into space, it slightly turns horizontally to reduce fuel used. On a rocket their is a 'nose' to help the rocket cut through the pressure of the air when flying.
We made straw rockets. We made our rockets out of plastic straw and paper as fins then used another straw to make the rocket fly. To help our rocket fly we had to make a lot of changes and variations to find our best flying rocket. The variable we changed was the fins. The winners were; Lukah - 6m and 40cm; Heavenly - 5m 90cm; Fau - 5m 80cm.
