In the experimental intervention of the research, Web 2.0 tools supported instruction was applied to the experimental group and curriculum-based instruction was applied to the control group. While Canva, WordClouds and VistaCreate tools were used in Web 2.0 tools supported instruction; Science Course book was used in curriculum based instruction. The study group of the research consisted of 5th grade students of two secondary schools in a district located in the southeast of Turkey. A total of 100 students, 50 for the experimental group and 50 for the control group, took part in the study. The data of the study were collected with four data collection tools: Sun, Earth and Moon Concept Test, Sun, Earth and Moon Achievement Test, Constructivist Learning Environments Scale and 21st Century Skills Scale. As a result of the research, it was seen that web 2.0 tools supported teaching was an effective method in eliminating the misconceptions of 5th grade secondary school students about the world and universe, increasing their achievement in the world and universe, increasing their perceptions of constructivist learning environments and 21st century skills. In addition, it was concluded that the achievement of female students in the experimental group in the subject of world and universe was higher than that of male students. According to this result, it can be said that web 2.0 tools supported instruction is more effective than curriculum-based instruction in teaching the world and universe subject to 5th grade students
