“This is a working model of acid rain. Factories release harmful gases like sulfur dioxide and nitrogen oxides into the air. These gases rise into the atmosphere and mix with water vapor in the clouds to form sulfuric and nitric acid.When it rains, this mixture falls to the ground as acid rain.Acid rain damages forests, … Read more
This is a rotating wheel model showing the seed germination cycle.As we rotate the top wheel, we can see the different stages in the life of a plant — from a seed, to germinating seed, then a seedling, followed by a young plant, and finally a mature plant that produces seeds again. This cycle shows … Read more
This is a detailed Nuclear Power Plant Working Model. The process starts in the fusion building (reactor), where nuclear fission generates heat. This heat is transferred via hot water pipes to the turbine building, where steam spins a turbine connected to a generator.Electricity is produced and sent through transmission lines to homes.The excess heat is … Read more
This is a working model of a solar-powered house. It shows how solar energy can be harnessed from the Sun using a solar panel installed on the roof. The panel converts sunlight into electricity, which lights up the house.This model promotes renewable energy, helps reduce electricity bills, and is environmentally friendly.The surrounding green garden adds … Read more
This model shows the contrast between afforestation and deforestation.On this side, afforestation is shown where more trees are planted. It supports biodiversity, maintains the water cycle, reduces pollution, and keeps the Earth cool. On the other side, deforestation is shown. Trees are cut down for construction, farming, or industries, which causes loss of wildlife, air … Read more
