The 1st Science Festival organized by the Department of Science Education was carried out through activities prepared by our third-year pre-service science teachers. Within the scope of the festival, a total of 20 experiments related to the fields of physics, chemistry, and biology were conducted, with the participation of 5th, 6th, 7th, and 8th grade students. While the participants had the opportunity to explore scientific concepts through hands-on experiences, our third-year pre-service teachers from the Department of Science Education were able to improve their professional knowledge and skills by putting their subject-matter knowledge into practice. The event provided an educational, interactive, and enjoyable learning environment that fostered curiosity and interest in science.
