Abstract

The beach environment is located between the terrestrial and marine environments, being a transition ecosystem between them, which is why it presents several characteristics that are caused by various influences, which makes this environment an interesting place to carry out various activities. field studies and classes to better understand it. Based on these facts, the present study aims to develop a practical teaching guide to evaluate the morphodynamic and abiotic characteristics of beaches, in order to deepen students' knowledge on the topic. For this purpose, Iporanga beach located in the municipality of Guarujá, SP, was chosen, where a field class was held on March 2, 2015 and the following methodologies were applied to the sand strip, topography assessment, granulometric analysis, organic matter content, temperature and for the marine environment, the height of the waves, the depth of the photic layer, the color of the water, temperature and salinity were verified, in order to classify the type of beach to which the study site belonged. After the analysis, the beach was classified as protected, presenting waves with an average size of 75cm of the diving type, with a photic zone of 2.16 m, salinity 35, average temperature of 30°C, presenting very fine sediment, with organic matter content. varying between 7.38 and 0.3%. After the practical application of the established methods and the results obtained through the field guide, it proved to be highly effective for carrying out practical classes in beach environments, demonstrating easy execution and arousing great interest among students.
