The case of low understanding of science in early childhood is a problem that affects many children in various countries. This can affect their cognitive development, their interest in science, and their ability to participate in a society that is increasingly dependent on science and technology. Knowledge of the introduction of science in early childhood is an important topic in the development of children's education. The use of Eco Enzymes or environmental enzymes in this context may be an interesting method, but it should be implemented with caution in accordance with the guidance of educational experts and scientists. The method used is a literature review or literature review, which is an approach used to investigate or compile information that has been previously published in the form of journal articles, books, research reports and other sources relevant to the research topic. It is important to explain this science learning concept in a simple way that is appropriate for children's understanding and make this learning a positive, educational experience. Through a creative and interactive approach, children can grow up with an awareness of environmental sustainability and the importance of protecting our earth. The learning approach with Eco Enzym in early childhood tends to involve active and practical learning, which can be more effective in introducing science concepts than learning passive. Additionally, further evaluation and further research may be needed to measure the long-term impact of learning science with Eco Enzym in early childhood.
