Rockets!

We've been working away on a wee project over the last couple of weeks - we've been building rockets!  There was a lot of talk leading up to the Big Day:
- did it matter if you had three or four fins?
- what if your fins were 'bung'?
- would it be a disadvantage to have a longer rocket?  shorter?
- would the air pressure be less in a longer rocket?
- how big should the cone be?  
- what if your cone was 'bung'?
- would the angle of release make a difference to how far your rocket would fly?

We had a lot of questions that needed answering!  Everyone decorated their rockets in an ultra cool way, and proudly named their rockets.  Then it was finally time to find out who was the ultimate rocket builder - congratulations to Ashlee H (first), George (second) and Elysia (third).  The rockets that these students made flew well over 30m - AWESOME!
