STEAM stands for Science, Technology, Engineering, Art, and Math. Each of STEAM’s five subjects shares a common approach and focus. By integrating STEAM subjects into our everyday teaching activities, we develop our students' 21st-century skills such as problem-solving, product design, creation, critical thinking, teamwork, use of technology, and gain solving skills for problems they encounter in daily life. The project provides an opportunity for both teachers and students to get to know the STEAM subjects and find an opportunity to integrate STEAM into their teaching activities. During the project, there will be different activities, where STEAM subjects and everyday life will meet. We develop 21st-century skills for students aged 4-10 by preparing activities for different ages. It will also contribute to intercultural interaction and cooperation by sharing the studies with students and educators from different cultures or cities using various web 2.0 tools.
