For the unit “weather and its change”, studied in second grade of junior high school, we developed teaching materials with AR technology, changing isobars that are displayed on the weather map in order to facilitate an understanding of the regularity of the blowing of the wind. It has a function that can display superimposed isobars listed on the weather chart paper and display them three-dimensionally from the numerical value of the pressure of each isobar. This function is intended to enable students to understand the regularity of the strength of the wind, in which lesser intervals of isobars rapidly lead to a pressure change, and the regularity of the wind direction, where the wind is blowing from greater pressure isobars to less pressured ones. As a result of teaching practice with the teaching materials, the proportion of students increased in terms of acquisition of scientific concepts and understanding of regularity. From these findings, it became clear that AR teaching materials are valid to understand how the wind blows in relation to isobars.
