Analysis of Brownian Motion by Elementary School Students

TL;DR

This study engaged elementary students in analyzing Brownian motion through video analysis and dice experiments, effectively stimulating curiosity about microscopic phenomena and physical mechanisms.

Contribution

It introduces an educational workshop that combines video analysis and simple experiments to teach elementary students about Brownian motion.

Findings

Students found the workshop interesting despite difficulty

The workshop successfully stimulated curiosity about microscopic phenomena

Participants gained understanding of physical mechanisms of Brownian motion

Abstract

To stimulate the intellectual curiosity of elementary school students, we conducted a workshop in distance education aimed at exploring the microscopic world inside a cell. In this workshop, elementary school students motivated to learn more on the subject of science analyzed movies of the Brownian motion of micrometer-sized particles suspended in water, using an open-source software, Tracker. These students then performed two-dimensional(2D)-random walk experiments using a dice game sheet to examine the physical mechanism of Brownian motion. After the workshop, we conducted a questionnaire-based survey. Many participants answered that the contents were difficult but interesting, suggesting that our workshop was very efficient to stimulate the curiosity of motivated students.
