Get the grand kids looking for posties route and his discarded rubber bands, losts of them to build a crossbow launcher and a swept wing sabre fighter projectile, just a thought.

Some of these kid's homework projects are a nightmare for parents.  :}

 Mere laziness on the teachers part is my opinion >>:-( ! All modern teaching industry theory dressed up as 'encouraging creativity' which is hardly creative if the the project is so ringed around with constraints based on health and safety fears that all the creations are so similar and probably feeble.

Despite what some people think, these projects are a nightmare for teachers.
Ask any ex-teacher. There are hundreds of them. Not because the job attracts lazy feckless people, but because the hours and rigours of the job are crazy.

Booster glider.... Since it isn't a true rocket, a couple of swept
wings might keep it gliding for distance.  :-))

Ahh, a sensible answer at last.

I do believe that Nordlys put this request on for help from others, and not to raise a debate about the pros and cons and technicalities of what a "rocket" is and isn't,nor what the school has called such a project and all of those flippant answers has probably confused him and his grand son more than helped them.

There is a wealth of initiative and brain power on this site that could come up with sensible answers to a problem, and I would have thought that such a request to help a young man would have been of great interest to you all.

       Yes it is of interest, but asking adults on this forum they can well ask what are the objectives and constraints? If the objective is as far as possible then tigertiger's post #3 raises a most valid point, and #14 may well favour the 'heavier' child , and in this particular project how BIG can the elastic band be, or how many?
            It may well be an interesting activity for a child, especially in today's world of mostly 'digital' entertainment, but if the child cannot design his own solution to the problem posed- but not necessarily construct it( which could well pose risks)-- and then have it analysed as to its merits and impracticalities along with the other pupil's efforts, then how much will he/she actually learn? To do this sort of thing properly surely the children would each need to have a teacher  selected/matched pile of materials to design and construct their ''rocket'' to prove their ideas and construction?
