Experiential Plant Learning Program Using the Five Senses

Introduction

Overview of Experiential Learning Using the Five Senses

Most plant learning experiences focus on visual observation and appreciation. However, among the 270,000 known species of land plants, there are many that can be enjoyed intuitively through all five senses: plants with interesting textures such as soft, rough, or hard surfaces (touch); strongly scented herbs and flowers with pleasant or unpleasant odors (smell); edible plants (taste); and plants used in musical instruments (hearing). Experiential learning using such plant materials not only allows students to enjoy and become familiar with plants, but also sharpens their senses and provides hands-on opportunities to understand the diversity of plants and how they support our daily lives. In this class, we conducted an outreach program for students who have difficulty visiting the botanical garden. Potted plants grown at the garden were brought to the school, allowing students to participate in hands-on learning experiences on site.

We selected around 40 potted plants that can be enjoyed through each of the five senses, such as plants that are fun to touch, smell, or visually striking, and prepared them for the program（see About Plants to Enjoy with the Five Senses）. The program was adapted in consultation with teachers to suit each grade level and developmental stage. This included introducing quizzes that link plants to daily life, emphasizing activities that engage the five senses, and adjusting other content as needed.

During the actual class, students moved around the different stations, and they appeared to enjoy the activities. Students’ responses varied by individual and group. Some eagerly handled the materials on their own, while others did so when prompted by a teacher, yet each group showed some engagement at one or more stations.

In post-class surveys for teachers, many commented that the students were able to enjoy learning through activities engaging all five senses, and that the program was highly effective. Responses indicated that participants were able to learn about the uses of plants, suggesting that the objectives of the program were successfully achieved. Similar survey results were obtained from both the elementary and junior high departments, suggesting that, despite differences in developmental stages and growth, students were able to enjoy learning. Additionally, some responses noted that the program allowed lessons that could not be conducted at school. In particular, plants that are difficult to grow outdoors in the surrounding area, such as bananas and other tropical species, which are not usually seen, received especially positive reactions. As for the plants that did not attract much interest, opinions were divided. However, because there were three corners (touch, smell and taste, and practical uses such as musical instruments), even if some plants received little attention, it seems that participants were able to enjoy at least one corner or type of plant.

On the other hand, some participants noted as a point for improvement that they would have liked to spend a little more relaxed time exploring the activities in depth. The class duration and the number of plants for participants to experience will need to be adjusted in the future according to developmental stages and other factors.
