Sequência investigativa do pêndulo simples via Arduino e Phyphox aplicada no ensino remoto

Abstract

We use the investigative methodology in remote teaching to work the simple pendulum. We seek to study in a practical way the main factors that influence the period of the simple pendulum by doing this through the investigation. Students were encouraged to build a simple homemade pendulum and, with little influence from the teacher, carry out their investigation. During the investigative sequence, we used three different ways to measure the period, seeking to compare its results and propose discussions regarding experimental errors. Each method seeks to reduce experimental errors by introducing different technologies in the form of measurement. With the results obtained we approach the equation for the period of the simple pendulum. We use the equation to determine the acceleration due to gravity and analyze the errors of each measurement. The investigative sequence and the educational product were adapted for remote teaching, requiring the recording of videos and the formulation of online forms. The application took place in classes from different segments (elementary and high school) in order to compare the results. During the sequence, depending on the proposed activity, we have different levels of investigation. Our results indicate that it is possible to apply an investigative sequence remotely. For distance learning, the activities must be easy for the students to build, otherwise there is a reduction in the investigative level.
