Early Childhood Agricultural Learning Through Tree Walks and Hydroponics: A Soil Science Extension Case Study
Abstract
Early exposure to agriculture and the environment helps children develop a basic awareness of nature, food systems, and sustainability. This study examined how two hands-on activities, (1) tree walk and (2) simple hydroponic planting session, shaped preschool children’s understanding of plants, their environmental roles, and sustainable practices. The programme, conducted in Bintulu, Sarawak, involved 40 children aged 4 to 6 from two local kindergartens. Before and after the activities, simple picture-based surveys was used to assess their recognition of tree species, plant categories, and basic hydroponic concepts. The results showed that children were able to name trees, recognise benefits such as soil health and food provision, and explain that plants in hydroponics grow using nutrient water. Most of the children said they enjoyed the activities and wanted to try similar planting at home. The use of familiar crops made the activities easier for children to understand and recall. These findings show the value of incorporating simple agricultural activities in early education and highlight how soil scientists can contribute through child-friendly outreach programmes.
