Resumen de Carbon for Water Treatment: A Chemistry Experiment That Is Accessible for Vision Impaired People
Ruth Patchett, Robyn Watson, Joe Davies, Zoe Schnepp
Chemistry experiments are challenging for people with vision impairment (VI) as results often rely on visual observations such as a color change. This puts pupils with VI at a disadvantage both in their scientific learning and in their development of broader life skills. In this paper, we describe a simple and low-cost experiment on the adsorption of fragrances by activated carbon. The experiment can be used in a class by sighted pupils and pupils with VI, enabling all pupils to fully engage with the lesson. A trial of the experiment with VI pupils in mainstream schools demonstrates the accessibility of the experiment and effectiveness for teaching the concepts of adsorption, surface area, and water treatment challenges.
