STEAM is an education approach that is intertwined with daily life. We created our project to develop students' 21st century skills such as problem solving, critical thinking, collaboration, product creation and reasoning through the activities we will create. Our project will contribute to children's pedagogical development and academic skills. Based on the lives of astronauts, we will learn about space with our students, starting from a healthy and balanced diet, by using STEAM activities, by doing and by having fun, helping them gain 21st century skills. We also plan to provide digital media literacy with Web2.0 tools and digital games.
