The study lasted for 6 weeks in total and a different Web 2.0 tool was applied to the students every week on the “Microsoft Teams” platform. The model of the research is a mixed model in which quantitative and qualitative methods are combined. In this direction, the "Reproduction, Growth and Development Unit Achievement Test in Living Things" was used as a quantitative data collection tool, and the "Reproduction, Growth and Development Unit Worksheet in Living Things" was used as a qualitative data collection tool. SPSS program was used in the analysis of the quantitative data, and content analysis was used in the analysis of the qualitative data. As a result of the study, it has been found that online education applications supported by web 2.0 tools have a positive effect on students' achievement in the unit "Reproduction, Growth and Development in Living Things". In the study, it was found that the students gave more correct code and frequency outputs with a significant difference after the application, and that they correctly associated the unit concepts with each other.
