As part of their scientific investigations last week, Ms. Mullen`s Sixth Class made parachutes. Using material, string and some unsuspecting toy teddies, the boys predicted the effects of a range of variables on the motion of their parachutes.
Would longer strings improve flight?
What effect would a change of fabric have on the parachute?
Would the size of the parachute sail make difference?
Like all good scientists, they carefully measured each variable before predicting what the outcome might be.
Then, it was time for a test flight. Our double height stairwell proved an ideal testing ground. Assembling around the stairwell, the unsuspecting teddies were attached to their parachutes and released for the test flight.
And the results? The scientists concluded that the parachutes fared better if made from a heavier material. The best parachute shape was rectangular rather than square or circular. Eight strings were better than six. Medium length strings were best and finally, the bigger the chute the better.
Best of all, no teddy suffered during this experiment, apart from mild trauma on take off!
And the class will create the ultimate parachute this week, using all the evidence from their investigation.
