In this category, we add all the diy school project models for pre-college students (Class 11 / Grade11 ).
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
