“…Nowadays, an important goal in teaching physics is increase student's attention and motivation. To this purpose, excellent strategies using games and smartphones have been proposed in the literature to teach physics, namely kinematics [1][2][3]. Another way of increasing learners' engagement is to use robots as a teaching tool.…”

In this paper, we aim to show strategies for improving graph interpretation skills at middle and high school students using OZOBOT® BIT, a small and relatively low-cost programmable robot which had been used to teach programming to young children. OZOBOT’s speed can be controlled by drawing lines with colour codes, as well as through a visual block programming system. We show how to take advantage of these features of the robot by recording appropriate motions that students can explore by video analysis, manipulating data, characterizing the motion and associating graphs to predictions of physical models.

“…Although the use of the smartphone camera to analyze and track moving bodies is already widespread [4,5], normally this type of approach involves, at least, the execution of two stages at different times: first the video is recorded, then analyzed on the smartphone itself or on a computer.…”

In this article we show how to use a smartphone’s flash as a strobe lamp, allowing one to analyze simple periodic phenomena such as water dripping from a tap, among others. Finally, we propose a simple setup for the ‘reverse rain’ experiment that became famous in the film ‘Now You See Me 2’. The proposed experiment allows to approach in a fun and engaging way concepts related to periodic phenomena such as frequency, period and duty cycle.

“…Atualmente, as tecnologias digitais estão presentes de forma contundente no cotidiano da sociedade com a informática, o mundo virtual e a realidade aumentada tornando tudo mais automatizado e mais rápido. Em consonância com essa realidade, novas metodologias são desenvolvidas para auxiliar a aprendizagem dos alunos, para que eles possam compreender melhor e de forma mais responsável as tecnologias atuais, além de permitirem que a utilização das chamadas tecnologias de informação e comunicação (TIC) facilite a compreensão dos diversos conteúdos abordados em sala de aula (PARREIRA;CARVALHO, 2019;SANTOS;RODRIGUES, 2017;CARVALHO et al, 2014;DIAS et al, 2018;CRUZ;.…”
