How many clear layers does a solar heater plate need? Glazing test
A clear cover over a black plate lets sunlight in and slows heat from escaping. Testing zero, one and two layers shows the benefit and the point where extra layers stop helping.Show detailsHide detailsWhat it shows
A clear cover over a black plate lets sunlight in and slows heat from escaping. Testing zero, one and two layers shows the benefit and the point where extra layers stop helping.
You will need
- Three identical shallow cardboard trays
- Black paper and foil for lining
- Three identical small black cups or tins
- Clear plastic sheets or a transparent file cover, and card strips as spacers
- Three thermometers
- Water and a measuring cup
- Tape and a wooden board
Safety: Handle cut plastic edges carefully. An adult must supervise testing near a roof edge or a hot surface. Do not leave water in a sealed container; let air escape.
Take it further: Place a layer of foil under the black paper and see if the extra insulation helps.

Waste paper, sawdust and crop leaves can be pressed into fuel blocks. Burning equal masses under adult supervision and timing a water boil shows the energy in each fuel.
You will need
- Old newspaper torn into bits
- Sawdust or dry crop leaves
- A bucket of water and a cloth to squeeze
- A tin can with holes as a mould

Microbes break down organic waste without air and release biogas, mostly methane and carbon dioxide. Measuring balloon size over days compares how much gas different feedstocks give.
You will need
- Three 500 ml plastic bottles
- Three balloons
- Fresh cow dung or buffalo dung slurry

A rocket stove has an insulated chimney and a small fuel feed so the fuel burns hot and clean. Comparing the boil time against a three-stone fire shows how a design change saves fuel.
You will need
- One large tin can and one medium can
- Sand or ash for insulation
- A metal grill or three nails for the pot rest
- Dry twigs

Before you start
How to choose a good project
Six things to think about before you decide. A project you understand and finish well beats a big one you rush.
Start with a question
Good projects answer a question you are curious about: why does iron rust, which fabric keeps tea hottest, how does a robot follow a line? A question gives your project a purpose.
Check what is asked
Find out whether your teacher wants a working model, a still model or an investigatory project, the size limits, the topic or theme, the date, and whether ready-made models are allowed.
Match your time and class
Each idea here shows a class band, a difficulty and a rough time. Choose something you can finish properly with time to test it, rather than something huge you have to rush.
Pick science you can explain
Judges and examiners ask how it works. Choose an idea whose science you understand, or can learn from your textbook and the free ebooks, and practise explaining it.
List materials and costs
Write down everything you need before you start. Many models use things from home; motors, LEDs, sensors and boards are easy to buy as spare parts or in a kit.
Make it your own
Change one thing and measure what happens, add a chart of your readings, or show a real-life use. Even a well-known model becomes yours when you add your own observations.
Plan your time
A four-week project timeline
Work backwards from the date of your exhibition or submission. Short of time? Do the same steps faster, but never skip testing.
- 4 weeks before
Choose and get it approved
- Shortlist two or three ideas
- Write your aim or question in one sentence
- Show your teacher and agree the idea
- 3 weeks before
Read and collect materials
- Read the science in your textbook and a free ebook
- Sketch the design with measurements
- Collect or buy the materials and spare parts
- 2 weeks before
Build and test
- Build one part at a time and test each part
- For an investigation, repeat each reading at least three times
- Write every observation in a notebook with the date
- 1 week before
Write the report and chart
- Aim, materials, method, observations, result and conclusion
- A neat table or graph of your readings
- A chart or poster with a labelled diagram
- Last 2 days
Rehearse
- Practise a one-minute explanation out loud
- Prepare answers to the questions below
- Pack spares: cells, wires, tape and glue
On the day
Present it with confidence
You will usually have a minute or two to explain your project, then questions. Practise both out loud at home.
A one-minute explanation
- 01Name and question“My project is a … It answers the question …”
- 02What it showsOne sentence of science, in your own words.
- 03How it worksPoint to each part as you explain it.
- 04What you foundYour readings or result, and what they mean.
- 05Real lifeWhere the same science is used every day.
Questions judges often ask
- What does your project show, in one sentence?
- How does it work? Which law or idea of science is behind it?
- What did you change, and what did you measure?
- What went wrong while you were making it, and how did you fix it?
- Where is this idea used in real life?
- What would you improve if you made it again?
What your project file needs
- Title page with your name, class and school
- Aim or question
- Introduction: the science behind it
- Materials list
- Method, step by step, with a diagram
- Observations in a table
- Result and conclusion

Stay safe
Safety rules for every project
Read these with a parent before you start. Ideas that need extra care carry their own safety note.
Never use mains electricity
Power your models with cells, batteries or a low-voltage adapter. Never connect anything home-made to a wall socket.
Adult help for sharp and hot tools
Cutters, blades, glue guns, soldering irons and drills need an adult beside you. Cut away from your body on a board.
Chemicals with care
Use only safe household materials at home. Acids, stains and other lab chemicals are for the school lab with your teacher. Wear goggles and never taste anything.
Flames only with an adult
Candles and burners only with an adult present and water nearby. Tie back long hair and keep paper away.
Look after batteries
Do not short-circuit a battery, mix old and new cells, or puncture or heat a lithium battery. Remove batteries when the model is stored.
Small parts away from little ones
Magnets, button cells and small parts can be swallowed. Keep them away from younger brothers and sisters, and wash your hands after making.
What is the difference between a working model, a still model and an investigatory project?
A working model moves or works to show a principle, such as a windmill that lights an LED. A still model shows how something is built or arranged, such as the layers of the Earth. An investigatory project asks a question and answers it by experiment: you change one thing, measure the result and draw a conclusion from your readings.
Can I buy a ready-made project?
Check your school’s rules first: some competitions want models made by the student, and some allow ready-made ones. Either way, you must understand how it works and be able to explain it. A good approach is to build from a kit, or to add your own measurements and chart to a ready-made model.
How long does a school project take?
Each idea here shows a rough time for the making. Leave extra time for reading, testing, the report and practice: three to four weeks from choosing to presenting is comfortable for most school projects.
What should go in my project report or file?
A title page, your aim, the science behind it, the materials, the method with a diagram, your observations in a table, the result and conclusion, precautions, and the books and websites you used. The free ebook “Writing a Science Project File” explains each part.
What if my model stops working on the day?
Carry spare cells, wires and tape, and test everything when you arrive. Take a short video or photos of it working at home. If something still fails, explain calmly what should happen and what you would check: judges value understanding as much as a perfect model.
