List of Physics Projects for Class 12 CBSE Students: As a grade 12 science student, you should have come across several physics projects.

Growing from beginners level to higher-level project, these projects may however vary.


Today, we shall therefore try to look into some of these physics projects for class 12 students.

Are Physics Project for Class 12 Necessary?

You see, when you are a class 12 student, you tend to ponder on a lot of predictable questions in terms of your physics class.


Some of these, therefore, affect your result in the physics project as they determine your stands. These questions may however include;

  • What should I make for a physics project?
  • Is class 12 physics easy?
  • Which topic is best for projects in physics?
  • What is the best physics project for class 12?

These are the core among several other questions probably popping up in your head right now. Although physics projects may seem fun for some people, it, however, is a nightmare for others.

Now, this is because a lot of people aren’t really into the physical field representation of natural laws. Besides, not everyone can build.

So class 12 physics projects, help in a very great way to therefore empower grade 12 students with the needed physical practical’s of all they have learned in their physics class.

List of 20 Physics Projects for Class 12

Since it is not necessary to make hi-tech projects during in 12th class, simple and easy projects are more preferable.

This, however, is because they would be less time-consuming and easier to explain.

Here, therefore, are some of the most popular physics projects for class 12 students.


Electric Car

Making an electric car for your Physics project for class 12th will set you apart from your classmates. It is easy to make and fascinating to see it work which makes it a perfect option for a project.

The electric car works on a simple principle where two gears carry the transmission of force from the motor to a wheel and uses rubber bands that act as a belt.

You will therefore get to explore various concepts of physics like Aerodynamics, Conversion of Energy, Electric Circuit besides design while working on the project. 

Materials Required: A Plastic Board for Car Chassis, 4 Wheels, 4 Tire Rings, Battery Holder, Battery, Motor Mount, Electric Motor, Rubber Bands, Transmission Pulley, Screws, Paper Clips, Straw.


Electric Motor

Electric Motor is one of the most common and basic projects that you can think of.

Though the concepts involved in the motor are complex but making an electric motor is relatively easy.

With just a requirement of a coil of wire, a magnet, and a power source, it is a preferred choice for your Physics Project for Class 12 if you have limited time. 

Materials Required: Insulated Wire, Battery, Small Circular Magnet, Electric Tape, Modelling Clay, 2 Metal Sewing Needles, Knife.


How to Create a Visual Doppler

The following experiment is to check what happens to sound waves by creating a visual model about what happens when a vehicle passes by. 

The explanation for the Doppler effect is that each successive wave crest is from a position closer to the observer than the crest of the previous wave, as the source of the waves is heading towards the observer.

This project creates a visual simulation of what happens to the sound waves to make them sound very different as the vehicle approaches than that when it exits.

Materials Required: Ruler, Scissors, Tape, Toy car, Two pieces of coloured construction paper, Some plain paper, and a marker or a camera.

Buoyancy 101

The following experiment is to check and determine whether a rise in water density would cause a boat hull to sink deeper in the water to an observable degree as its temperature elevates from 5 degrees C to 95 degrees C.

This shows that increasing water temperature allows water molecules to move further out, decreasing upthrust in turn, and causing more water to displace by a floating mass as its buoyancy decreases.

If the water molecules spread outward due to high temperature, a large rise in water temperature can produce a noticeable difference in the water’s surface or even a small floating point.


Materials Required: 10 Identical Styrene Model Boats, 128 grams of steel, and a Digital Thermometer

Heat Transfer in an Incandescent Lamp

How much of the electrical power supply of an incandescent lamp do we lose by thermionic emission from the filament?

If these damages are large, the operational performance of incandescent lamps could substantially increase by their elimination.

The power output can decompose into thermionic emission and thermal-radiation elements using the electricity, filament temperature, and ambient temperature details.


The conduction is sequentially dependent upon the temperature of the filament (Fourier’s Law). But the exposure, however, is proportional to the fourth power of the temperature of the filament (Stefan-Boltzmann Law).

Materials Required: 25-watt evacuated light bulb, programmable power supply, two high-precision digital meters, and a precise digital thermometer.

Insulation Value

The experiment is to equate straw insulation with traditional forms of insulation, which are fibreglass and rigid foam panels, which are in wide use today.

The most critical element in building an energy-effective contribution is adequate insulation.


Insulation will hold the heat inside during cold days. Isolation will trap the sun outdoors on hot days. Insulation materials are structures that avoid the transmission of heat from a house inside and outside.

To insulate walls, floors, and pipes, we may use various materials.

Materials Required: Speakers, Insulation, and Digital Thermometer

Observations of Gas in the Infrared Spectrum

The aim of this project was to research the effect of gas chemical properties on its ability to process and transmit infrared radiation by the gas transmission of infrared light.


The primary aim was to mask a plainly transmissive gas heating element.

The molecular structure of gas that can specifically influence transmissivity in the infrared spectrum is confirmed by the evidence from both forms of the test.

The can of air has high absorption zones, allowing areas of low transmittance that caused some obstructing in the infrared spectrum.

Materials Required: PVC pipe, Spectroradiometer, 8-12 micron infrared camera with digital imagery, Blackbody, and gases.

Marvellous Magnetics

The purpose of this experiment was to decide how diamagnetism could influence levitation using graphite, paper, plastic, aluminium foil, or no substance.

In relation to how many artificial objects today use magnetism or even diamagnetism, this study may even interact with the earth.

The world’s fastest train, for instance, is in Japan and runs on magnetism.


Materials Required: Levitation Pedestal, Graphite, Adjustment Screw, Paper, Aluminum foil, and Plastic in place of the Graphite. 

Long and Short Wavelength Colors

The aim of the project is that the houses were painted in both solid colours (red, blue, green, orange) and mixed colours (red/blue and green/orange). This project, therefore, examines the interior and exterior temperatures of houses and their insulation rates.

Data revealed that the order of internal temperature readings from peak to lowest matched the wavelengths of colour from longest to shortest fairly closely.

Combination colour houses fell between their stable counterparts in general. Exterior temperature data shows that followed by red, red/blue, grey, blue, orange, and control, the green/orange house was the warmest.


The highest insulation rate, followed by green, green/orange, red/blue, red, orange, and control, was obtained from the blue home.

Materials Required: Oil paints, Control house was painted white and Digital and Infrared Thermometers.

Use and Impact of Recycled Materials for Thermal Insulation

Fibreglass, pine shavings, polystyrene, polyurethane, cellulose, perlite, polyethene foil, or bubble wrap where the goal of this experiment is to find which recycling process would be an effective electricity insulator.

This could be an asset in the summer, but even time would be spent on heating the house in the winter. It also took a bit longer than the other materials to cool fibreglass and only averaged around 12 minutes to heat it.


As it warmed easily and also trapped heat to save energy, fibreglass was by far the most powerful insulator.

Materials Required: Particle Board, Digital thermometer, Light Bulb, and Cardboard boxes. 

Hydro Power

The following project is however conducted to learn about the first-hand force of water.

At the foot of dams, hydropower plants are designed to take advantage of higher water pressure at the edge of a dam. The excess water is funnelled into a tube called a penstock into the dam.


The water is then concentrated on a turbine’s blades. The water pressure of the water transforms the engine, and a power generator turns the turbine.

Materials Required: Half gallon paper milk carton, Gallon of Water, Awl or 10p nail, Masking Tape, Ruler, Magic Marker, Pair of Scissors and Pad of Paper and Pencil to make Notes

Salt Water vs Tap Water

This experiment would be about magnets and water. Since water is diamagnetic, we use magnets to transfer water, which means it appears to move further from magnets and electromagnets.

A cookie tray with the magnets equally spread along the inside circumference of it.


Someone who studies water is a hydrologist. The study of the dynamics of electrically conducting fluids is called magnetohydrodynamics (MHD for short). One of them is salt water. 

You could levitate a frog if you had a powerful enough magnet.

Diamagnetic and paramagnetic are also compounds. In addition, this may be the data that I require. To see whether the water is flowing or not, I would have to use rubber duckies or food colouring.

Materials Required: Rubber, Magnets, Angel food pie tin, Food coloring, Timer, and Tape.
