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 model represents the paper output system of a printer. Real printers use motors to push printed paper out. Here, we’re using a simple hydraulic mechanism. When we press this syringe, the connected syringe inside pushes the printed paper forward. It’s a basic example of how hydraulics can be used in machines to move things … Read more
This is a hydraulic bridge working model. It uses Pascal’s Law of pressure in fluids. When I push the syringes, water transfers pressure to lift the bridge arms just like a real drawbridge opens for ships to pass. It’s an eco-friendly, simple, and efficient technology used in many real-world machines. How to Build the Hydraulic … Read more
Life Cycle of a Plant (Step by Step) To demonstrate the stages of a plant’s life cycle in a rotatable, colorful, and interactive way, helping students and visitors easily understand how plants grow. How to Make (Step-by-step): Step 1: Make the Base Step 2: Create Rotating Circle Step 3: Add the Life Cycle Stages Step … Read more
Introduction The kidney is one of the most important organs in the human body. Every person has two kidneys, located on either side of the backbone just below the ribs. They are small and bean-shaped but play a very big role in keeping us healthy. The main function of the kidneys is to clean the … Read more
Introduction A water dam is a large wall or barrier built across a river to stop and store water. The water collected behind the dam forms a big lake called a reservoir. This stored water is very useful for people, farms, and industries. Dams provide water for drinking, farming (irrigation), and factories. They also help … Read more
An escalator is a moving staircase that carries people up and down between different floors of a building. It is powered by an electric motor and works with a chain of steps that keep moving in a continuous loop. Escalators are very useful in places where many people need to move quickly, such as shopping … Read more
Introduction A water overflow alarm is an electronic device designed to prevent the wastage of water. It alerts people when a water tank becomes full, usually by producing a loud sound or turning on a light. This simple system helps in saving water, electricity, and avoids unnecessary mess caused by overflow. The device works using … Read more
Introduction Water is one of the most important resources for life, but fresh water is limited and many areas face shortages. To solve this problem, two important methods are used: rainwater harvesting and water purification. Rainwater harvesting means collecting rainwater and storing it for future use. The water is usually collected from rooftops or open … Read more
This 3D model demonstrates both Solar and Lunar Eclipses.The Sun, Earth, and Moon are represented by these three colored balls.In a Solar Eclipse, the Moon blocks the Sun’s light and casts a shadow on Earth.In a Lunar Eclipse, the Earth comes between the Sun and Moon, casting a shadow on the Moon.This model helps us … Read more
Geothermal energy uses heat from deep inside the Earth. In some places, hot water and steam come from underground. This steam can run turbines to make electricity. It is clean, renewable, and available all year. Countries like Iceland and the USA use geothermal power a lot. It can also be used to heat houses and … Read more
“This is a combined renewable energy model. On the left, hydroelectric power is generated when water flows and turns the turbine. In the middle, wind energy converts kinetic energy of air into electricity. On the right, solar energy is captured by solar panels to power homes.All these sources are eco-friendly, renewable, and sustainable. Here’s a … Read more
This is a 3D model of an animal cell using a quarter-cut plastic ball to show the inside. Each organelle is placed in its correct position. The nucleus controls the cell, mitochondria generate energy, the ER transports materials, and the Golgi body packages them. The cytoplasm fills the space, and the cell membrane controls what … Read more
This model shows how the Earth rotates on its axis, causing day and night. The Sun remains stationary and glows using an LED. The Earth rotates using a slow motor, and as it turns, different parts face the Sun or move into shadow. This helps us understand the real reason for day and night on … Read more
This project demonstrates how 3D geometric shapes are used in real-life buildings and structures. Every building in this model is based on a different 3D shape like cubes, cuboids, cylinders, cones, spheres, pyramids, and prisms. This helps students understand geometry through real-world applications like homes, towers, domes, lighthouses, etc. How to Build the 3d Shapes … Read more
The human hand is one of the most important parts of our body. It helps us hold, grab, write, and do many daily tasks. The hand can move in different ways because it has joints, which are places where bones meet. A hinge joint is a type of joint that works like a door – … Read more
