Why is Spatial Ability Important yp y p y Spatial ability has been shown to be a critical skill in many different fields: { Art/design –when we imagine composition/layouts { Music – when we “hear” in our mind ngineering hen we create drawings { Engineering – when we create drawings { Chemistry – understanding chemical compositions iology – isualizing structures { Biology visualizing structures { Science – envisioning processes eology – ineral compositions { Geology mineral compositions { Medicine – understanding anatomical systems { And the list goes on…
