In this category, we add all the diy school project models for secondary school students,(Class 9 / Grade 9).
Where students can do themselves step by step for their school exhibition or fair
This working model shows the effect of global warming and how greenhouse gases like carbon dioxide trap heat in Earth’s atmosphere. When sunlight enters, some of it reflects back, but greenhouse gases trap most of the heat, raising the Earth’s temperature.In this box, you can see how the trapped heat makes the area warmer, simulating … Read more
This is a working model of a volcano, which demonstrates how magma inside the Earth rises and erupts as lava. Inside the volcano, we have a red LED light that simulates the glow of hot lava inside.When the switch is turned on, the LED glows, showing the intense heat and molten rock inside a volcano.Optionally, … Read more
This is a working model showing Air, Water, and Land Pollution. On the left, we see factories and vehicles releasing smoke, causing air pollution.In the middle, the plastic tray represents a lake, which is getting polluted by factory waste using this syringe mechanism. You can also see a truck dumping garbage into the river. This … Read more
“This is a Hydraulic Gate Working Model made using syringes and cardboard.It demonstrates Pascal’s Law – the principle behind hydraulic systems. When I push the first syringe, water pressure moves the second syringe’s plunger, lifting the gate.Such hydraulic gates are used in dams, canals, and flood control systems. Materials Required: Video Steps to Make the … Read more
This is a hydraulic lift working model in a scissor shape, made using syringes and ice cream sticks/cardboard. It demonstrates Pascal’s Law, where pressure applied on a fluid in a closed container is transmitted equally.When we press one syringe, the water moves into the other, pushing it out and lifting the scissor mechanism. This model … Read more
