Here is a lesson I recently taught to a bright KS3 group at the end of ratio and proportion. It begins revising sequences before introducing Fibonacci and then the golden ratio. Demos of this in nature, construction and finally the human body. The main task involves students taking measurements of faces (I include my own but have spared you that) and then finding how close the measurements are the golden ratio and therefore ranking the celebrities in order of attractiveness. SMSC - Can beauty be reduced to a ratio?
