Pressure studies

7N had a chance to utilise all they have learned about pressure today. 

They set up water rockets and used air pressure to power them. 

They investigated how the angle of trajectory and the amount of water in the rocket changed the flight length. 

A lot of energy went into pumping the rocket. 

It was great fun launching the rockets but it could well be that it was not a completely fair test because of the gusty wind today.
