In this category, we add all the DIY school science project models for secondary school students (Class 10 / Grade 10).
Class 10 school projects are a very important and turning point for the students.
The models are covered in the following subjects
We have listed all exciting science models (both working and still models) that you can implement with the materials available at home based on the latest syllabus
For these listed projects we have provided detailed explanations including step by step video on how to make this model diy at home.
By following the video instructions students can do themselves develop the models step by step for their science exhibition or science fair
Do these DIY projects, students will get good knowledge on these topics.
Concept / Principle: This project works on the principle of photoconductivity — using an LDR (Light Dependent Resistor).The LDR’s resistance decreases when light falls on it and increases in darkness.This change controls a transistor or relay circuit, which automatically turns ON the LED (street light) at night and OFF during the day. Main Concept:LDR senses … Read more
Concept / Principle: This model demonstrates how wind energy is converted into electrical energy using a wind turbine.When air (wind) blows on the blades, it makes them rotate — this rotation drives a DC motor (acting as a generator) that produces electric current to light up an LED bulb. Scientific Principle:Mechanical energy (rotation of turbine) … Read more
Concept / Principle: This model demonstrates the concept of global warming — how increased greenhouse gases (like CO₂, methane, etc.) trap heat in Earth’s atmosphere, raising the planet’s temperature.The rotating Earth represents our planet, and the LED lights + burning wooden sticks (or safe red LEDs) represent the rising heat and pollution from industries and … Read more
Concept / Principle: This project is based on infrared motion detection — it senses changes in infrared radiation (heat) caused by a moving object like a human body.When motion is detected, it activates an LED light and a buzzer, simulating a security or automatic light system. Scientific Principle: Infrared sensors detect IR radiation emitted by … Read more
Concept / Principle: This project demonstrates how solar energy can be converted into electrical energy using solar panels to power small household components like LED lights, fans, or a motor — showing the concept of renewable energy and sustainable living. Scientific Principle:Solar panels contain photovoltaic (PV) cells that convert sunlight (solar radiation) into electricity (DC … Read more
Concept / Principle: The hydraulic crane works on Pascal’s Law, which states: “Pressure applied to a confined fluid is transmitted equally in all directions.” When you push fluid (water) from one syringe, it transfers pressure through a tube to another syringe, causing movement — just like in real cranes that use hydraulic systems to lift … Read more
Concept / Principle: A geostationary satellite is a satellite that orbits the Earth once every 24 hours — the same time the Earth takes to rotate once on its axis.Because both rotate at the same rate in the same direction, the satellite appears stationary above one fixed point on Earth (like over India or the … Read more
This model demonstrates the laws (rules) of exponents in an interactive and visual way.Using a rotating wheel or disc system, each rotation reveals a different law of indices with an example — helping students easily understand how powers behave in multiplication, division, and powers of powers. Laws of Indices / Exponents: 1️⃣ Product Law:am×an=am+na^m \times … Read more
Concept: This interactive maths model helps students understand the surface area and volume of 3D geometric shapes like cube, cuboid, cylinder, cone, sphere, and pyramid.The LED light glows when you press the correct formula button for a given shape, and the buzzer alerts when it’s incorrect — turning a simple model into a fun learning … Read more
Tired of watching your water bill skyrocket while your urban garden thirsts for more? Imagine a garden that practically waters itself, saving you money and the planet. This video reveals a simple DIY system that recycles household water, making your urban garden thrive without the constant tap of high costs. This model shows how wastewater … Read more
Here’s a step-by-step guide to make an Air Pollution and Its Effects Working Model easily at home or for your school science exhibition. This model demonstrates the causes, effects, and preventive measures of air pollution in a creative way. Concept: Air pollution is caused by harmful gases, smoke, and dust entering the atmosphere. It affects … Read more
In this video, we’ll show you how to make a Pollution Working Model that demonstrates six major types of pollution — Air, Water, Sound, Light, Soil, and Land Pollution. This simple and creative DIY science project is perfect for the 2025 school science exhibition and helps spread awareness about protecting our environment. Concepts Covered: How … Read more
In this video, learn how to make a renewable energy working model that demonstrates three clean energy sources — solar power, wind energy, and hydroelectric power. This project helps explain how natural resources like sunlight, wind, and water can generate electricity without harming the environment. Perfect for school science exhibitions, STEM projects, and eco-awareness fairs! … Read more
Aim / Objective To demonstrate how mechanical energy can be converted into electrical energy using a DC motor as a generator, and how that generated electricity can power devices (like LED lights). Materials Required Model Construction / Steps 1️⃣ Prepare the Base 2️⃣ Fix the Motors Tip: You can also use a gear wheel or … Read more
Aim / Objective To demonstrate how plants use sunlight, carbon dioxide, and water to produce food (glucose) and release oxygen, showing this through a rotating half-earth model with a plant setup. Materials Required Model Construction / Steps 1️⃣ Prepare the Base 2️⃣ Make the Rotating Half Earth Cut a thermocol ball or plastic globe into … Read more
