ABSTRACT
A plane mirror is the name given to any flat mirror. When light hits a mirror, it bounces off the surface of the mirror with very little scattering (this is because the surface is so smooth). This means if one distinct ray hits a mirror then one distinct ray will be reflected off the mirror. This chapter describes the procedure for investigating how light reflects off a mirror. This real-world science experiment is structured as a problem-solving activity thus helping KS3 science teachers to engage students effectively in the secondary school classroom. First, background science knowledge for this experiment is provided, along with the learning objectives, list of materials needed for the experiment, safety and technical notes, and a list of engaging activities to be performed by students. Data collection ideas are subsequently provided, together with useful questions to ask the students and also suggestions for homework.
