In this research, an activity based on 5E model for STEAM education was implemented. The activity plan was designed by researchers for the "Reflection in the Mirror and Absorption of Light" in the 7th grade science class. The research was implemented in a 7th grade group of 30 students in 2017-2018 academic year. Five STEAM focused activities were completed over 5 weeks (20 hours in total). The students performed the activities by applying the engineering design process with group work. Kaleidoscope, reflective sculpture, solar oven, spectroscope, and vehicle of light show designs were generated in the activities. As a result of the observations and interviews made in the research, positive results have been obtained that students made creative designs as much as possible and liked to work with the activities. The activities shared in the article are concrete examples of STEAM education in classroom for teachers and researchers.
