  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.
