Create an image of a simple handmade school physical model about air quality and climate, made from cardboard, colored paper, cotton, and easy classroom materials. The model should look realistic but easy for students to build. It should be a 3D diorama on a cardboard base and include labeled parts showing: layers of the atmosphere (troposphere, stratosphere, etc.) using stacked paper layers; cotton clouds showing acid rain falling from polluted clouds; a factory and cars releasing pollutants (carbon dioxide, sulfur dioxide, nitrogen oxides); greenhouse effect with sun rays trapped in the atmosphere; ozone layer; trees showing photosynthesis; a small Earth section showing global warming effects like melting glaciers and flooding; a catalytic converter or pollution-control idea; renewable energy like solar panels and wind turbines as solutions. Use arrows and labels for processes like acid rain formation and greenhouse gases. Make it colorful, clear for presentation, and built only with simple materials available at school. Mehr sehen
