What is included
The listing says what is in the box; listings marked "with report" include a printed investigatory report. Read it before the viva, and take your own readings.
Which topics suit which class
Topics that often suit each class from 10 to 12. Your syllabus and your teacher's list have the final word.
Class 10Current electricity and its magnetic effects.
- Ohm's law2
- Resistors in series and parallel5
- Electric motor1
- Electromagnetic induction4
- Refraction and lenses
Class 11Mechanics and heat, measured rather than only shown.
- Simple pendulum
- Newton's third law1
- Bernoulli's principle
- Thermal expansion
Class 12Electronics and AC circuits, popular as investigatory projects.
Highlighted topics have products listed in this catalogue; the others can be asked for on WhatsApp.
What an investigatory project file usually contains
Class 10 to 12 files follow the investigatory format: the experiment, your readings and what they show.
- Cover page, and a certificate page for your teacher's signature
- Acknowledgement and index
- Aim and introduction
- Theory, with the laws and formulas used
- Apparatus and materials
- Circuit or set-up diagram
- Procedure, step by step
- Observations: your readings in a table, with a graph where it helps
- Calculations and result
- Precautions and sources of error
- Conclusion and bibliography
Boards and schools set their own rules on the order, the length and whether the file is handwritten: follow your teacher's instructions.
Safety notes
Working models are safe to handle when a few simple rules are kept, at home, on the way to school and on the display table.
Magnets and moving parts
Strong magnets pinch fingers and harm phones and cards. Keep fingers clear of spinning fans, gears and belts.
Batteries
Use the battery type the model is made for, never mix old and new cells, and take the battery out once the show is over.
Mains power
School models should run on batteries or a proper adapter. Never wire a model straight to a wall socket; let an adult check any adapter.
Warm parts
Motors, bulbs and resistors can get warm. Switch off between demonstrations and keep paper and cloth away from them.
Younger children
Small parts, magnets and button cells are a choking hazard. Keep them out of reach of little brothers and sisters.
Tools
Cutting, hot glue and soldering are jobs for an adult, or with an adult beside you.
Ready-made, kit or your own build?
All three end with a model on the table. The right one depends on the time left and how much of the building the student will do.
Ready-made model
Best whenWhen the date is close, or the circuit is beyond the class level.
- Arrives assembled, so it can be tested the day it arrives
- Check the listing for the board size, the power source and whether a report is included
- Still read the report and run it several times: judges ask how it works
DIY kit
Best whenWhen there are a few weeks and the learning matters most.
- The student assembles it, which gives a lot to talk about
- Plan time for building, testing and fixing
- Needs basic tools, and an adult for cutting, hot glue or soldering
Spare parts
Best whenWhen you are repairing a model or building your own design.
- Single parts: motors, LEDs, switches, batteries and wires
- List what your circuit needs before you order
- Test each part before you fix it in place
Practical and viva
How to present an investigatory project
Examiners want to see that you did the experiment and understood it. Present it in the same order as the file.
State the aim
What question the project answers, in one sentence.
Explain the theory
The law or principle, the formula, and what each symbol stands for.
Show the set-up
Walk through the circuit or apparatus and the role of each component and its value.
Show your readings
Your observation table and graph, and how you took each reading.
Give the result
What the readings show, the precautions you took and the likely sources of error.
Answer from the circuit
Expect "why this resistor?" or "what if the capacitor is removed?" Know the circuit, not only the file.
Tip: Run the experiment yourself and record your own readings, even with a ready-made set-up.
Questions about Physics
Still have a question?
Chat on WhatsAppWhich class is a physics model right for?
Each listing names its topic. Match it to the chapter you are studying this year; the table of topics by class on this page is a rough guide, and your syllabus and teacher have the final word.
Does the model come with a project report?
Only where the listing says so. Cards in this catalogue carry a "With report" badge when the listing mentions a report, and the listing on the marketplace says what is in the box.
What is the difference between an investigatory project and a working model?
An investigatory project answers a question through an experiment: you take readings, record observations and draw a result, and the report follows that format. A working model demonstrates a device or a law. Practicals in class 11 and 12 usually ask for an investigatory project; exhibitions accept either.
Do I still need to take my own readings?
Yes. Even with a ready-made set-up, run it yourself, record your own observations and be able to explain every component. Examiners ask about the circuit and your readings.
Which physics model is easiest to explain?
One with a single principle you can see working: a series and parallel circuit, an electromagnet, a hydraulic brake on Pascal's law or a simple generator. Choose one from a chapter you have already studied.
How is the model powered?
The marketplace listing describes the power source. Many school working models run on cells or a 9V battery; if the listing does not say a battery is included, buy one, and test the model at home before the day.
Can I get a model on a topic that is not listed?
Message us on WhatsApp with the topic, your class and the date you need it by. We reply with whether it can be made, the price and a dispatch date.
How early should I order?
Early enough to test the model at home and practise before the exhibition. The marketplace shows the delivery date for your PIN code before you pay; for a model made to order, tell us your date on WhatsApp first.
