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 is a 3D atom model showing its internal structure.The center or nucleus contains protons and neutrons, while electrons revolve around it in orbits. Each component is represented with colored balls and glowing LEDs, controlled using switches.This model demonstrates how atoms are structured and the role of subatomic particles. Video Construction Steps: Step 1: Prepare … 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
Concept Overview: The human heart is one of the most important organs in the body. It is a muscular organ, about the size of a fist, located in the chest slightly towards the left side. The heart works like a pump, sending blood to all parts of the body. The heart has four chambers – … Read more
Introduction The human digestive system is a group of organs that helps the body break down food, absorb nutrients, and remove waste. It starts from the mouth and ends at the anus. In the mouth, food is chewed by teeth and mixed with saliva, which contains enzymes to start breaking down starch. The chewed food … Read more
Geothermal energy is a type of renewable energy that comes from the heat stored inside the Earth. This heat comes from deep underground, from rocks, magma, and hot water reservoirs. Geothermal energy can be used to produce electricity and to heat buildings, greenhouses, and water. The process works by drilling wells into the Earth to … Read more
A Thermal Energy Generator converts heat energy into electrical energy. One simple and popular method uses a Thermoelectric Cooler (TEC) module. TEC is a small device that can generate electricity when there is a temperature difference between its two sides. In this setup, one side of the TEC is kept hot (using a candle, solar … 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
