ABSTRACT
This chapter describes the procedure for investigating the pH of different metal and non-metal oxides. 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, such as test tubes, test tube rack, measuring cylinder, universal indicator, pH colour chart, nitric (V) acid, phosphoric (V) acid, potassium hydroxide, sulfuric (VI) acid, sodium hydroxide, limewater and eye protection; 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.
