Criação de um minilevitador acústico ultrassônico de baixo custo como produto educacional no ensino de Física

Abstract

This monograph aims to create a low cost ultrasonic acoustic mini levitador. This levitator is an educational product in physics in the area of acoustics whose objective to improve the teaching of physics by approaching acoustic phenomena that are not normally analyzed as often in high school as acoustic levitation of small bodies. This product also serves as a didactic tool for high school teachers, especially for public school teachers. A small historical introduction to acoustic levitation, a theoretical explanation of acoustic levitation, the procedures for the assembly of the low cost ultrasonic acoustic mini levitador and a lesson plan with an investigative methodology consisting of a research demonstration were made. The elaborate educational product shows to be fully feasible for application in a high school classroom, mainly in the public school, due to its innovation, ease and low cost.
