About Science

General science and environment working models for class 1 to 9: phases of the moon, seasons, day and night, the revolution of the earth, layers of the atmosphere, an earthquake sensing alarm, a solar street light and solar house, and solar and wind energy conversion. They fit EVS, geography and general science chapters, and the energy and environment themes at science exhibitions.

Tips

  • Models with a light or a motor (phases of the moon, a solar house) hold the judges' attention longer than a chart
  • Use the printed report, where the listing includes one, for the explanation card next to the model

Ordering

Buy from the product card on the marketplace, or message us on WhatsApp for a topic that is not listed.

Which topics suit which class

A rough guide to the topics that suit each class. Pick one from a chapter you are studying this year, so the "why this topic?" question answers itself.

Class 1 to 5The earth, the sky and the seasons.

Class 6 to 8Weather, energy and the environment around us.

Class 9Resources and energy conversion.

Highlighted topics have products listed in this catalogue; the others can be asked for on WhatsApp.

What a project file usually contains

A short file beside the model helps the judges and helps you remember what to say. A typical file for class 1 to 9 has these parts.

  • A cover page with the title, your name, class, section and school
  • The aim: what the model shows, in one or two lines
  • Materials used, including the battery or power source
  • A labelled diagram or circuit diagram
  • How it works, step by step, in simple words
  • Where the same idea is used in real life
  • A conclusion: what you found out or learned
  • Sources: the books and websites you used

Your school's format comes first. Where a listing says "with report", use the printed report to write your own explanation, not to read aloud.

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.

  • Water near circuits

    In water cycle, rain alarm and irrigation models, keep the water well away from the battery and the wires.

  • 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
    See the 9 products

  • 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
    DIY kits

  • 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

At the exhibition

How to explain a working model

Judges move from table to table, so a short explanation in a clear order works best. These six steps cover what they usually ask.

  1. Say what it shows

    One sentence with the name of the model and the idea, for example: "This model shows how a hydraulic brake uses Pascal's law."

  2. Name the principle

    State the law or idea behind it in your own words, and the chapter it comes from.

  3. Walk through the parts

    Point to each part in the order the energy, water or signal flows, and say what each one does.

  4. Switch it on

    Run the model and say what is happening and why. Keep a spare battery in your pocket.

  5. Give a real-life use

    Where the same idea is used at home, in a vehicle, in a factory or in nature.

  6. Be ready for questions

    How it could work better, what its limits are, and why you chose each part.

Tip: Practise aloud at home with a timer, then once more with someone asking you questions.

Questions about Science

Still have a question?

Chat on WhatsApp
Which class is a science 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.

How do I explain the model to the judges?

Say what it shows, name the principle, walk through the parts in order, switch it on and narrate, and give one real-life use. The six steps on this page fit into a short, practised explanation.

Which environment topics suit a science exhibition?

Renewable energy, water conservation, waste management and pollution are common exhibition themes. Check this year's theme with your school before choosing.

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.
