Electromagnetic radiation and the human body: a teaching sequence for high school in a STSE approach

Abstract

In this proposal, suggestions for approaches to working with electromagnetic radiation, its species and applications, with high school students are listed, especially with regard to its relationship with the human body. An interdisciplinary discussion takes place, involving subjects such as Physics, Chemistry, Biology and History, in a Science, Technology, Society and Environment approach, which promotes reflective and critical thinking in its apprentices, making them capable of inserting scientific knowledge into their realities, in order to seek the common good. Different types of electromagnetic radiation and their uses in contexts such as the Second World War and today are mentioned. Through this didactic sequence, based on Meaningful Learning, by David Ausubel, the aim is that Basic Education students can have access to content that has been restricted to higher levels, specifically regarding Modern and Contemporary Physics. As this is a proposal yet to be implemented, it is expected that data will be collected through Pre-Test and Post-Test questionnaires, the results of which will demonstrate its feasibility in effectively engaging students and promoting understanding of the benefits and implications of these radiations.
