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.
A hydraulic brake uses liquid pressure to transfer force from the brake pedal to the brake drum to stop a vehicle. In this working model, you will show how pressing a “brake pedal” moves hydraulic fluid (water or oil) through a tube to push a “brake shoe” against a “drum” (wheel). Working Principle Demonstrated: Pascal’s … Read more
This model shows how contaminated water causes several dangerous diseases. As the platform rotates, it displays different water borne diseases like Cholera, Typhoid, Hepatitis A, etc. Materials Needed: Step-by-Step Video Instructions: https://www.youtube.com/@howtofunda
n this video, watch a beautiful DIY working model showing the theme “Save Earth – Save Environment” made using simple materials like color paper, cardboard, and LED lights powered by a 9V battery and switch. The Earth is surrounded by people figures made from paper, rotating slowly with the help of a motor. Plants are … Read more
In this video, we demonstrate a simple and effective Earthquake Simulation and Seismograph Working Model for science exhibitions and projects! Watch how a vibrating platform simulates an earthquake and how a basic hanging cup seismograph records the tremors with zig-zag lines on paper. Perfect for school science fairs, physics projects, or earthquake-related demonstrations. Learn how … Read more
This is a working model of an electric bell. When the switch is turned ON, electric current flows through the circuit, powering the DC motor. The motor rotates the nut attached to its shaft, which hits the steel glass to produce a sound. This demonstrates the basic idea of how electric bells use mechanical action … Read more
This is a Tower Crane Working Model that demonstrates both 360° horizontal rotation using a robo motor, and vertical lifting using a slow DC motor. Such cranes are used in real construction to lift and move heavy materials. This model shows how motors, pulleys, and simple circuits help in lifting and rotating heavy loads efficiently. … Read more
This is a working model to show that salt water conducts electricity. Pure water is a poor conductor, but when salt (NaCl) is added, it dissociates into Na⁺ and Cl⁻ ions, which help carry electric current. This is why the LED/buzzer only works when salt is mixed with water. It demonstrates the concept of electrolytes … Read more
This is a Mini Lift Working Model. It uses a DC robo motor to pull a lift box up using woolen thread. The lift works like real elevators, where motors and pulleys lift the platform. The motor is powered by a 9V battery and controlled using a switch. It demonstrates basic principles of mechanical work, … Read more
This is a 3-pulley simple machine working model. It shows how pulleys reduce the amount of effort needed to lift a heavy object. The movable pulley provides a mechanical advantage, and the fixed pulleys change the direction of force. Such systems are used in cranes, wells, and elevators.” Materials Needed How to Make Simple pulley … Read more
This is a Kidney Working Model. The syringe represents the kidney, and the sponge or cotton acts like the nephrons which filter blood. When ‘blood’ (colored water) is pushed through the syringe, the cotton filters it and sends the clean fluid or ‘urine’ into the plastic tray, which represents the bladder. This demonstrates how our … Read more
This is a fire alarm working model using a tubelight starter. The starter contains a bi-metallic strip that responds to heat. When a flame (from a matchstick) is brought near, the heat bends the strip inside the starter, completing the electric circuit. This allows current to flow and activates the buzzer, simulating a fire alarm. … Read more
This is a Water Wheel Working Model. When water is poured over the bottle cap paddles, it rotates the wheel using kinetic energy of flowing water. This concept is used in hydroelectric power plants where water spins turbines to generate electricity. The model demonstrates conversion of water energy into mechanical energy. Materials Needed How to … Read more
This is a gravity-based water dispenser. When the water bottle is placed upside down, gravity pushes water toward the straw pipe. Opening the cap slightly allows air to enter, and water flows out through the straw into the glass. This demonstrates how gravity and air pressure can be used to dispense water without electricity or … Read more
This model shows how a water level indicator works. When the water reaches the level of the two safety pins, it completes the electric circuit, turning on the red LED light and the buzzer. This indicates that the tank is full and water should be stopped. It helps in preventing water overflow and wastage, and … Read more
This is an automatic street light working model without sensors. When a vehicle passes over a hump, it presses the push button below, turning on the LED street light. Once the vehicle leaves the hump, the button is released and the light turns off. This shows how street lights can work automatically using simple pressure … Read more
