The aim of this study is to investigate the effect of using the Z book in the teaching of the "Energy Conversions and Environmental Science" unit of the science course on the academic achievement, attitudes, and motivations of the students who are in the 8th grade. In the research, a quasi-experimental design, with pretest and posttest control groups, was used. The participants of the research, which was carried out in the 2020-2021 academic year, consisted of 60 secondary school students studying in two secondary schools in the Muradiye district of Van. The experimental group is comprised of 32 students, whereas the control group is comprised of 28 students. The unit, which lasted six weeks (24 lesson hours), was taught using Z books for the experimental group, while science textbooks were used for the control group. “Energy Conversions and Environmental Science Achievement Test”, “Science Attitude Scale”, and “Motivation Scale towards Science Learning” were three different of the data collection tools used in the study. The data were analyzed using an unpaired t-test, and it was found that while there was no difference in attitude or motivation between the experimental and control groups, there was a statistically significant difference between them in terms of academic achievement. These findings are thought to be the result of the unit being the final unit, the students' anxiety because of the pandemic period, and the fact that the research was only conducted for one unit.
