The aim of the current research is to investigate the effectiveness of a proposed unit on climate change and its relationship to the aquatic environment in developing environmental concepts and trends among agricultural secondary school students; The research used the experimental method, and a unit was prepared on climate change and its relationship to the aquatic environment, and a design test of environmental concepts and measures of trends on climate change and its relationship to the aquatic environment, and to test its effectiveness; It was applied to a group of 41 female students from Kafr Saqr Secondary Agricultural School, where the data was collected through the application of the concepts of climate change and water environment test to measure the growth of environmental concepts; And the scale of environmental trends after a single research group. Statistical analysis was also used to verify the validity of the hypotheses, and the data were presented, and the significance of the differences was tested inferentially using the T-test, which showed a sign of the differences between the mean of the research sample before and after in favor of the post application, where the results showed that there is a statistically significant difference In the scores obtained by the students of the experimental group in testing the environmental concepts related to climate change and its relationship to the aquatic environment before and after teaching the proposed unit in favor of the post application, as well as it turned out that there is a statistically significant difference in the scores obtained by the students of the experimental group in the scale of environmental trends to reduce change Climate and its relationship to the aquatic environment before and after teaching the proposed unit in favor of the post application.
After analyzing the search results; It turns out that the proposed unit is effective in developing environmental concepts and trends among agricultural secondary school students, and the research recommended the necessity of introducing climate change topics into agricultural science curricula, and the need to support agricultural secondary education curricula with environmental concepts and trends of climate change.
