5, 4, 3, 2, 1... We have blast off!

Year 6 had a fantastic time setting off their water rockets today in science - many thanks to those parental contirbutions of plastic bottles!

Although getting soaked, they had a thrilling time pumping the air into the bottle rockets and watching them whizz away.

Each set of children worked with a different volume of water in their bottle so as to establish which volume of water would project the rocket the furthest length.

We are still crunching the number, however, in these early stages we realised that the rockets with the lesser water travelled the furthest. This is because those with more water are heavier and so found it a struggle to take off. Also, these bottles have less space for air inside; the air being pumped into the bottle causes a build up of pressure, when there is no space left for air, the bottles are projected forward with the release of pressure in the bottle.
