kids how old? i'd be careful using this area as a basis for a thesis. by saying you want to exemplify the basic characteristics of what should instill architectural interest in young people, you're opening yourself up to attacks on what you consider architecture to be. what fundamental elements comprise excellence in the exploration of architectural form, context, elemental arrangement. personally i'd provide spaces where different contrasting elements could be explored to create differring and contrasting visual, oral, and emotional states.
for example provide a room where the sources of natural light can be manipulated by use of easy to adjust shading, panels of colour, the subtle nuances created by diffusion. another space could have wholly adjustable wall planes where the ideas of a floor plan can be expressed and explained in real time. another space could be purely for material. i'd imagine a pitch black room where you are invited to explore the texture and grain of timbers, stones, concrete, rough and smooth, glass, cold steel and warm cloth. any of these could be combined, along with whatever you come up with, to provide a series of exploratory devices to enlighten young people and invite them to come to their own conclusions on what creates the spaces they desire.
examine your own work to divine your own priorities as to what creates good architecture. then use simple and practical tools to enlighten the people you are designing your school for.
