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 how food moves through the human digestive system using peristalsis. Each syringe represents muscle movement that pushes food from one organ to another. Starting from the mouth, food travels through the esophagus to the stomach, then into the intestines where digestion and absorption take place. Finally, waste is expelled through the … Read more
Demonstrates how heat from the Earth’s core is used to generate electricity using steam turbines, and how that electricity is transmitted via transmission towers and poles to light a bulb. In this geothermal model, heat from deep inside the Earth heats underground water, producing steam. This steam rises through a pipe and spins a turbine, … Read more
Here’s a creative and practical Thermal Energy Generator (Heat to Electricity) Working Model idea using a TEC (Thermoelectric Cooler) to power a DC motor (for rotation) and a buzzer (for sound). This is ideal for science exhibitions, especially under energy conversion themes. This model demonstrates the conversion of thermal energy directly into electrical energy using … Read more
This 3D model of a hibiscus flower is designed to demonstrate the structure and parts of a complete flower. Made using cardboard, tissue paper, fevicol, and paint, it creatively represents essential parts like petals, sepals, stamen, pistil (stigma, style, ovary), and leaves. The model helps students visually understand the reproductive system of flowering plants. Each … Read more

“Hello everyone!Welcome to my maths working model project video.Today, I’ll be showing a fun and interactive rotating shapes model.This model uses DC motor and switches to display different 2D shapes like square, triangle, circle, and more — each shape appears when I press a switch!” Objective of the Project “The goal of this project is … Read more
“Hello everyone!Welcome to my science project video.Today I’ll be presenting a working model on hydroelectricity — one of the most important renewable energy sources in the world. Let’s see how we can generate electricity using water!” What is Hydroelectricity? “Hydroelectricity means generating electricity using flowing water.This happens in hydropower plants where dams are built across … Read more
“Hello everyone!Welcome to my science project video.Today I will show you a working model on wastewater purification — a very important topic in today’s world, where saving water is more important than ever.” What is Wastewater? “First, what is wastewater?It’s the dirty water that comes from our homes, schools, and industries — from bathrooms, kitchens, … Read more
1. Wind Energy Is a Renewable Source Wind energy is renewable and sustainable — it will never run out as long as the sun shines and the Earth rotates. 2. Wind Is Caused by the Sun Wind forms due to uneven heating of the Earth’s surface by the Sun, which creates pressure differences — wind … Read more
1. Converts Heat to Electricity A thermal power plant generates electricity by burning fuel (like coal, oil, or gas) to produce steam, which drives a turbine connected to a generator. 2. Steam Is the Main Driver Water is heated to a high temperature to turn into high-pressure steam. This steam spins the turbine blades — … Read more

It helps reduce electricity bills, cuts pollution, and supports green energy. Through this project, students can understand the basics of renewable energy, … Read more
This model demonstrates an automated flood prevention solution using simple sensors and motor mechanisms. When rainwater is detected, the system activates a submersible pump to drain water from the basement, thus preventing flooding. This model is especially useful for urban smart homes, low-lying building basements, and monsoon-prone areas. The project combines basic electronics with environmental … Read more
