ABSTRACT
A pinhole camera is an example of a camera obscura, which means ‘dark chamber’. These camera obscuras were originally dark rooms where light entered through a small hole in one wall, projecting the image outside the room onto the opposite wall in the room. This chapter describes the procedure for designing and making a pinhole camera. 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.
