Layers of the Atmosphere

Environmental problems and especially the problem of environmental pollution is one of the main problems that pose great threats to humans and other living things today and that all countries of the world should take measures. The problem of environmental pollution, which has been discussed for centuries and defined as a global problem in recent years, has become more evident with the increase in economic activities (Özoğlu, 2023). Waste materials affecting the environment are gradually increasing and pose a significant threat to the lives of humans and other living things. Based on this current problem, an educational material on ‘Layers of the Atmosphere’ was prepared for the 10-15 age group by using all kinds of waste materials that have the potential to pollute the environment. With the help of the prepared material, a test comparing verbal and visual expression was applied to the 10-15 age group. Firstly, a verbal explanation was given about the layers of the atmosphere without using any material. After this verbal explanation, a pre-test consisting of 10 questions on the subject was applied to this group of students for 10 minutes. Then, the subject was visually explained to the students using our educational material prepared from waste. The post-test (same questions) was applied to the same students again (within the same time frame) and the results were analysed. When the results were analysed, it was seen that the correct rate in the post-test increased compared to the pre-test, and the number of blank and incorrect questions decreased. When these tests are analysed, it can be said that visual expression is more effective on students than oral expression. It is thought that this project will increase the environmental awareness of the 10-15 age group.
