On Friday, April eighth we had our penultimate subject journey of the educational faculty yr, whereby we went to go to the fourth graders on the Tucker Elementary Faculty in Milton. Thanks Professor Eno Ebong for sponsoring this subject journey, and PhD college students Chinedu and Nicholas from her lab for serving to out (and Hadeel and Tasha from our workplace as nicely!).
Working within the library of the college, we ran the day’s exercise for two teams of youngsters, for a complete of 75 fourth graders. I led the primary group of actions with volunteers while Hadeel stepped up and led the second group.
The actions consisted of Paper Towers and Reverse Egg Drop – an exercise we haven’t achieved in awhile. For Paper Towers, college students had some very cool towers – notably college students on this group centered on aesthetically pleasing towers – i.e. fairly towers (see the loopy formed tower backside left). Many towers had spires of assorted sizes and shapes, to each enhance their most top but in addition to look good.
Through the reverse egg drop exercise – through which college students designed gadgets to catch falling eggs (fairly than the basic egg drop through which college students construct a protecting shell across the egg and drop that) – college students got here up largely with one type of design – a sq. or rectangular field flat on the bottom with cushioning inside. These work decently nicely with low drop heights, however wrestle with greater drop heights (as there is no such thing as a actual crumple / influence zone – the egg pushes by way of the cushioning then nonetheless hits the stable ground). I feel including some extra instance footage into my presentation in addition to speaking about crumple zones may assist – actually explaining the physics of what is going to occur to their egg. Both means – we realized a precious lesson in engineering – issues don’t at all times work the primary time – you attempt, attempt, attempt till you (your design) succeeds.
