Today, the development of technology, the increase in urbanization, global warming, etc. Due to these factors, forests and nature have begun to disappear. With our project, we will make students understand the importance and necessity of forests for all living things in our world by using the STEM Approach. They will understand that forests are our source of oxygen, as well as their necessity for other living things. They will understand that forests and nature mean life, that they are our lifeblood. We will enable our students to make their learning processes more meaningful and to gain and develop their 21st century skills by using the STEM education approach so that they can learn by living and experiencing. With the STEM education approach, we aim to make the learning processes of our students more meaningful
