Globalization and the irrational use of natural resources have led to an ecological crisis manifested in food shortages, environmental pollution, the extinction of many plant and animal species, climate change and the overpopulation of the Earth. In order to start solving the consequences, it is necessary to be aware of yourself and your way of thinking and to act towards the education of new generations who will respect the relationship between people and nature. It is important to promote environmental activities already in preschool, which provides a basis for the permanent adoption of environmental habits. The kindergarten plays an important role as an institution and the educator as the initiator of activities and the creator of spatial and material conditions. It is necessary to create good environmental programs and structure ecoactivities so that they bring results. The basic condition for ecological learning is play with an emphasis on research. The paper explains a variety of activities that can be carried out as a motivation to create emotions towards nature and adopt ecological habits. Creativity and innovation in thinking are important characteristics of environmental awareness, and they are developed through art activities, so in this paper we propose the activity of 3d modeling as a means of learning about biology and ecology. The material chosen for making the 3d model is clay because of its naturalness, the sensory possibilities it provides and the children's interest in shaping it. The aim of the proposed activity is to create and express emotions towards wood through clay modeling which requires longevity and deep reflection during making. The forerunners of making 3d models are a motivational story with important information about the habitat of trees, a conversation about the importance of trees and a research activity of studying different trees in nature.
