It may look simple to the eye, as most beautiful things do, but the functioning of a bird's wings is quite complex indeed. Here, using everyday materials like straws and skewers, we make a lovely model to demonstrate the movements of a bird's wings which allow it to move upwards (and propel forwards) when the wings flap downwards. However, when the wings flap upwards, a bird doesn't need the reverse to happen! And this model shows exactly how ingenious evolution has been in designing the flying gait of birds and other airborne creatures! ______________________________________________________________________________________________ Find other interested videos here -    • Grade 6 (NCERT)   ______________________________________________________________________________________________ Buy our products - https://www.thinktac.com/available-co...
