How resistance changes with the length and thickness of nichrome wire
Show detailsHide detailsWhat it shows
The resistance of a wire is directly proportional to its length and inversely proportional to its area of cross section (R = rho L / A). Doubling the length doubles R, and twisting two equal wires together halves it.
You will need
- About 2 m of nichrome heater wire (from an electrical repair shop, under Rs 40) or thin iron binding wire
- A metre scale and a wooden plank to tape the wire along
- Two AA cells in a holder
- A digital multimeter
- Crocodile clip leads
- A screw gauge from the lab, or the wire gauge printed on the packet
Safety: Nichrome gets warm when current flows; keep the circuit closed only while reading. Cut wire with pliers, not a knife, and an adult must help with the cut ends, which are sharp.
Take it further: Repeat with wires of two different gauges and plot R against 1/A for a fixed length.
PhysicsEasy
Demonstration board comparing series and parallel torch bulbs
Show detailsHide detailsWhat it shows
In a series circuit the same current flows through every bulb and the voltage is shared, so each bulb glows dimly and all go out if one is removed. In parallel each bulb gets the full cell voltage, glows brightly, and the others stay lit when one is removed.
You will need
- Six 2.5 V torch bulbs with holders (about Rs 10 each)
- Two AA cells in a holder (3 V)
- A cardboard or plywood board about 30 cm by 40 cm
- Insulated single-strand wire, 3 m
- Three slide switches or paper-clip switches
- A multimeter to read current and voltage
- Drawing pins and glue
Safety: Cells only, never mains. Bulbs and wires get slightly warm; switch off when not demonstrating. An adult must help with the cutter when stripping wire.
Take it further: Replace one bulb with an LED and a 220 ohm resistor and explain why the LED needs the resistor.
PhysicsMedium
Conductivity of salt water against concentration with two carbon rods
Show detailsHide detailsWhat it shows
Pure water barely conducts, but dissolved salt gives free ions that carry current. The current through a salt solution rises with concentration at first and then levels off as the ions crowd each other.
You will need
- Two carbon rods pulled from dead zinc-carbon cells (an adult must open them) or two graphite pencil leads
- Common salt, a teaspoon and a kitchen weighing scale
- A 250 ml measuring jug and five identical glasses
- Three AA cells in a holder
- A digital multimeter
- Crocodile clip leads and a cardboard strip to hold the rods 3 cm apart
Safety: Cells only. Do not use the solutions afterwards for anything else. Wash hands after handling the carbon rods and wipe up spills, since salt water corrodes metal.
Take it further: Repeat at 10, 25 and 40 degrees Celsius for one concentration to show that conductivity of a solution rises with temperature.
PhysicsEasy
Electromagnet lifting power against number of turns and current
Show detailsHide detailsWhat it shows
The strength of an electromagnet grows with the number of turns of wire and with the current through it. Counting the pins it lifts for 20, 40, 60 and 80 turns gives a clear upward trend.
You will need
- A 10 cm iron nail or bolt
- About 5 m of enamelled copper wire (28 to 30 SWG, from an electrical shop)
- Two AA cells in a holder, plus a third cell for the current test
- A box of steel pins or paper clips
- Sandpaper to strip the wire ends
- A multimeter to measure current (optional)
Safety: The coil warms quickly; connect for only a few seconds per trial and let it cool. Pins are sharp; count them on a tray. Cells only.
Take it further: Compare an iron core, a steel bolt and no core at 80 turns, and explain which stays magnetised after the current stops.
PhysicsEasy
Homopolar motor from a screw, a cell and a neodymium magnet
Show detailsHide detailsWhat it shows
A current flowing through a magnet in a magnetic field feels a sideways force (F = B I L), and here that force makes the magnet and screw spin at hundreds of revolutions per minute. It is the simplest motor that works with no coil and no commutator.
You will need
- One AA cell
- A 5 cm steel screw or nail
- A small disc neodymium magnet, 10 to 15 mm (about Rs 30 from an online shop)
- A 15 cm piece of copper wire with the insulation stripped
- A second magnet and a paper cup for the extension
Safety: The cell is shorted while the motor runs and gets hot; run it only for 10 to 20 seconds at a time. Neodymium magnets snap together hard and pinch, and small ones must be kept away from young children. Cells only.
Take it further: Build a wire homopolar motor where a bent copper loop spins around the cell instead of the magnet.
PhysicsMedium
Shake torch: a magnet moving through a coil lights an LED
Show detailsHide detailsWhat it shows
Moving a magnet through a coil changes the magnetic flux through it and induces an emf (Faraday’s law), which lights an LED with no cell at all. Faster shaking and more turns give a brighter flash.
You will need
- A 15 cm length of PVC or a thick ballpoint pen barrel, 15 to 20 mm wide
- About 40 m of enamelled copper wire, 32 to 36 SWG (about Rs 150)
- A strong neodymium rod or stack of disc magnets that slides freely inside the tube
- Two LEDs (red works best, it needs only about 1.8 V)
- Two bottle caps or rubber stoppers to close the ends
- Tape, sandpaper and a multimeter set to AC volts
Safety: Keep neodymium magnets away from phones, cards and small children. Sand the enamel outdoors or over a bin. No cells are needed, so there is nothing to short.
Take it further: Add a diode bridge and a 1 F supercapacitor so the torch stores charge and stays lit after shaking stops.
PhysicsEasy
Mapping magnetic field lines of bar magnets and a current-carrying wire
Show detailsHide detailsWhat it shows
A small compass points along the magnetic field at each point, so plotting its direction step by step traces the field lines of a magnet. A wire carrying current also deflects the compass, showing that electric current produces a magnetic field (Oersted’s experiment).
You will need
- Two bar magnets
- A small plotting compass (about Rs 30) or five cheap button compasses
- Large sheets of white paper and a pencil
- A 1 m length of thick insulated copper wire
- Two AA cells in a holder and a switch
- Iron filings in a salt shaker for the optional picture
Safety: Cells only, and close the switch only for a few seconds at a time because the wire shorts the cells. Keep iron filings away from eyes and off the magnet surface (wrap the magnet in paper).
Take it further: Map the field of a coil of 20 turns with current flowing and compare it with the bar magnet map.
ChemistryMedium
Comparing water hardness of local samples by soap drop count
Show detailsHide detailsWhat it shows
Hard water contains dissolved calcium and magnesium salts that react with soap to form scum before any lather can form. Counting the drops of a standard soap solution needed to get a lasting lather ranks tap, borewell, RO, rain and bottled water from softest to hardest.
You will need
- A plain bathing soap, 2 g, grated
- Distilled or RO water, 200 ml, for the soap solution
- Five water samples of 10 ml each: tap, borewell or hand pump, RO or bottled, rainwater, and distilled water as a control
- Five identical small bottles with caps or test tubes with stoppers
- A dropper or a 1 ml syringe without needle
- A measuring cylinder or a 10 ml syringe
- A notebook and labels
Safety: Nothing hazardous, but samples from ponds or drains must not be used; an adult must collect borewell water. Wash hands after handling samples.
Take it further: Boil a portion of the hardest sample, cool it and retest; the drop count falls if its hardness was mostly temporary.
ChemistryEasy
Testing milk for added water, starch and detergent
Show detailsHide detailsWhat it shows
Three quick tests catch the commonest milk adulterants: a drop on a tilted plate flows slowly for pure milk but runs fast if watered, iodine turns blue if starch was added to thicken it, and shaking with water gives a thick lather if detergent was mixed in. The project compares packet, dairy and loose milk.
You will need
- Three milk samples of 50 ml each from different sources
- A smooth steel plate or glass slide
- Tincture of iodine diluted ten times (adult prepares)
- A dropper
- Three small bottles with caps
- Cornflour and a drop of liquid detergent to make known adulterated controls
- Labels and a notebook
Safety: An adult must dilute the iodine, which stains and must not be swallowed. Do not drink any sample used in the tests, and especially not the controls.
Take it further: Measure the density of each sample with a lactometer or by weighing 50 ml, since watered milk is less dense.
ChemistryEasy
Is the honey pure? Kitchen tests against sugar syrup
Show detailsHide detailsWhat it shows
Pure honey is a very concentrated sugar solution with little free water, so it behaves differently from honey diluted with sugar syrup: it sinks as a lump in water instead of spreading, is not soaked into blotting paper, and forms a thread between the fingers. Running the tests on branded, local and home-made syrup samples shows what each test can and cannot tell.
You will need
- Three honey samples of 2 spoons each from different sources
- A sugar syrup made by dissolving 7 spoons of sugar in 3 spoons of warm water (adult pours warm water)
- Four glasses of water
- Blotting paper or a tissue
- A spoon and a dropper
- A kitchen balance, optional
- Labels
Safety: An adult must handle warm water for the syrup. Do not taste samples that have been on blotting paper or in glasses.
Take it further: Keep a spoon of each sample open for a week and compare how much each one crystallises; real honey often does.
ChemistryEasy
Rate of reaction and surface area: whole, halved and crushed tablets
Show detailsHide detailsWhat it shows
An effervescent tablet fizzes in water as its citric acid and bicarbonate react. The same tablet crushed to powder finishes in a fraction of the time, because the reaction happens only at the solid surface and powder has far more surface. Timing whole, halved, quartered and powdered tablets gives a clean rate curve.
You will need
- Twelve effervescent tablets (vitamin C or antacid type) or ENO sachets
- Four identical glasses
- Water at room temperature, measured 100 ml per glass
- A stopwatch
- A spoon and a clean sheet of paper for crushing
- A balance if available
- Notebook
Safety: Do not swallow the tablets or the fizzing water during the test. Crush tablets inside folded paper so powder does not fly into eyes.
Take it further: Repeat the powder test in cold, room-temperature and warm water to separate the effect of temperature from surface area.
ChemistryMedium
Rate of reaction and concentration: vinegar strength by mass loss
Show detailsHide detailsWhat it shows
When baking soda reacts with vinegar, the carbon dioxide escapes and the flask gets lighter. Following the mass on a balance every 30 seconds gives a rate curve, and repeating with diluted vinegar shows that the rate falls as the acid concentration falls, while the total gas depends only on how much acid was present.
You will need
- A digital kitchen or lab balance reading 0.1 g
- A small conical flask or bottle
- Vinegar, 200 ml
- Baking soda, 20 g
- Measuring cylinder and water for dilutions
- A loose cotton wool plug for the flask neck
- A stopwatch and graph paper
Safety: Vinegar is a dilute acid; avoid eyes and wash hands. Never cap the flask tightly while it fizzes; the cotton plug lets gas out but stops spray.
Take it further: Keep the concentration fixed and run the reaction at three temperatures to compare the effect of temperature with that of concentration.
ChemistryMedium
Electroplating a steel key with copper from copper sulphate
Show detailsHide detailsWhat it shows
Passing a small current through copper sulphate solution deposits a layer of copper on the object connected to the negative terminal, while the copper anode slowly dissolves to replace the copper ions. A clean steel key or coin comes out with a bright copper coating.
You will need
- Copper sulphate from the school lab, about 25 g dissolved in 250 ml water (teacher prepares)
- A 250 ml beaker or glass jar
- A piece of thick bare copper wire or copper strip as the anode
- A clean steel key or old coin as the object to plate
- A 1.5 V to 4.5 V battery pack with two leads and crocodile clips
- Fine sandpaper, a little detergent and a cloth
- Gloves and safety goggles
Safety: A teacher or adult must prepare the copper sulphate solution and supervise throughout; copper sulphate is harmful if swallowed and irritates skin and eyes, so wear gloves and goggles and wash hands. Use only batteries, never mains, and give the used solution back to the teacher for disposal rather than pouring it down the drain.
Take it further: Plate two keys for 5 and 15 minutes and compare the colour and thickness of the coating.

Which cold drink is most acidic? Baking soda drop count
Show detailsHide detailsWhat it shows
Fizzy drinks and juices contain phosphoric, citric and carbonic acids. Counting the drops of a fixed baking soda solution needed to neutralise a measured volume of each drink, watched with a natural indicator, ranks them by acid content and links the result to tooth enamel damage.
You will need
- Small amounts of a cola, a lemon soda, an orange juice, a packaged mango drink and plain water
- Baking soda solution: 5 g dissolved in 100 ml water
- Red cabbage indicator or a few drops of phenolphthalein from the school lab
- A dropper or 1 ml syringe
- A 10 ml syringe or measuring cylinder
- Five white cups or small beakers
- Notebook
Safety: Do not drink any sample after indicator is added. Phenolphthalein, if used, must be handled by the teacher.
Take it further: Measure the pH of each drink with pH paper and discuss why pH and total acid do not rank the drinks in exactly the same order.
ChemistryMedium
pH of tea and coffee against brewing time and added milk
Show detailsHide detailsWhat it shows
Tea and coffee are mildly acidic, and the acidity depends on how long they brew and whether milk is added. Measuring pH with indicator paper for black tea, green tea and coffee brewed for different times shows how extraction of acids changes with time and how milk partly neutralises them.
You will need
- Black tea leaves, green tea leaves and instant or filter coffee
- Universal indicator paper or pH strips from the school lab or a chemist
- Hot water (adult pours) and a kettle
- Six identical cups and a timer
- Milk, 50 ml
- A white tile and tweezers for the strips
- A notebook for the table
Safety: An adult must pour the hot water and the brews must cool before any strip is dipped. Do not drink brews that have had indicator strips in them.
Take it further: Measure the pH of the same tea brewed in bottled, tap and borewell water to see whether the water itself shifts the result.
ChemistryMedium
Corrosion rate of iron nails against salt concentration
Show detailsHide detailsWhat it shows
Rusting is an electrochemical process that speeds up when the water conducts better. Nails kept in water with 0, 1, 3.5 and 10 percent salt for two weeks, then cleaned and weighed, show that salt accelerates corrosion, which is why vehicles and ships near the sea rust faster, and also that very strong brine slows it again.
You will need
- Eight identical plain iron nails, not galvanised
- Table salt and a balance reading 0.01 g
- Four jars with lids and distilled or boiled cooled water
- A measuring cylinder
- A plastic brush or coarse cloth for cleaning rust
- Sandpaper
- Labels and a notebook
Safety: Nails are sharp; carry them point down. Rust-cleaning should be done over newspaper and hands washed afterwards. No chemicals other than salt and water are used.
Take it further: Repeat with one jar of boiled, cooled water sealed with a layer of oil on top to show that removing oxygen almost stops rusting.

Comparing vinegar brands by drop titration with washing soda
Show detailsHide detailsWhat it shows
The acetic acid content of vinegar can be compared by titrating a measured volume with a standard washing soda solution until an indicator changes colour. Running three brands and a home-made dilution ranks them by strength and, with a simple calculation, gives an approximate percentage of acid to compare with the label.
You will need
- Three vinegar brands and a 1 to 1 dilution of one of them
- Washing soda (sodium carbonate), 10.6 g dissolved in water and made up to 1 litre, or a solution prepared by the teacher
- Phenolphthalein from the school lab, or red cabbage indicator
- A 1 ml syringe or a dropper with counted drops, and a 5 ml syringe
- Small white cups or conical flasks
- A notebook and calculator
Safety: Vinegar and washing soda solution can irritate eyes; wear goggles if available and wash hands. The teacher handles phenolphthalein. Nothing is tasted.
Take it further: Titrate lemon juice and lime juice the same way and compare their citric acid content, remembering that citric acid gives three hydrogen ions per molecule.
BiologyMedium
Foil on a leaf: where does the plant store starch?
Show detailsHide detailsWhat it shows
A leaf partly covered with foil for two days and then tested with iodine turns blue-black only where light reached it. Leaves make starch by photosynthesis, and photosynthesis needs light.
You will need
- A potted plant with broad soft leaves (such as money plant or balsam)
- Aluminium foil and paper clips
- Iodine solution (tincture from a chemist, diluted) and a dropper
- A kettle or hot water from an adult, a bowl and a cup
- Rubbing alcohol (isopropyl) and a white plate
Safety: An adult must handle the hot water and the alcohol. Alcohol is flammable: warm it only in a cup standing in hot water, never on a flame or stove. Iodine stains skin and cloth; wash splashes with water.
Take it further: Test a leaf from a plant with white patches (variegated) to show that only green parts make starch.

Napier's bones multiplication rods made from ice-cream sticks
Show detailsHide detailsWhat it shows
Each rod carries the multiplication table of one digit written in split boxes. Laying rods for 4 and 6 side by side and reading row 7 gives 7 times 46 = 322 by adding along the slanted lines, a 400-year-old calculating tool.
You will need
- 11 flat ice-cream sticks or card strips 2 cm wide
- A fine permanent marker
- A ruler
- A card frame with a numbered column 1 to 9 on the left
- A small box to store the rods
Take it further: Make a second set and use both to multiply numbers with repeated digits, such as 44 times 6.

Five Platonic solids folded from cardboard nets
Show detailsHide detailsWhat it shows
Only five solids can be made with every face the same regular polygon and the same number of faces at every corner: the tetrahedron (4 triangles), cube (6 squares), octahedron (8 triangles), dodecahedron (12 pentagons) and icosahedron (20 triangles). Each is folded from a flat net.
You will need
- Cereal-box cardboard or thick chart paper
- A ruler, compass and protractor
- A blunt knife or an old pen for scoring folds
- Glue or tape
- Paints in five colours
Safety: An adult must help with scoring and cutting.
Take it further: Make the cube and octahedron so one fits inside the other with vertices touching face centres: they are dual solids.

Rice-pouring proof that a cone is one third of a cylinder
Show detailsHide detailsWhat it shows
A paper cone and a paper cylinder with the same base radius and the same height are filled with rice. Exactly three cones of rice fill the cylinder, showing that the volume of a cone is one third of pi r squared h.
You will need
- Chart paper or an old X-ray sheet
- A compass, ruler and protractor
- Tape
- About 1 kg of rice, sand or rajma
- A tray to catch spills
- A measuring cylinder or a kitchen scale to check
Take it further: Make a hemisphere of the same radius from a ball cut in half and show it holds two cone-fulls, giving the sphere formula four thirds pi r cubed.

Unit circle trigonometry board with a swinging radius arm
Show detailsHide detailsWhat it shows
A 10 cm arm pivots at the centre of a circle on a grid. At any angle, the height of its tip above the horizontal is 10 times the sine and the distance along the horizontal is 10 times the cosine, so at 30 degrees the tip is 5 cm up and 8.66 cm across.
You will need
- A 30 cm square board
- Centimetre graph paper glued to the board
- A stiff card or aluminium strip 10 cm long as the arm
- A split pin or a bolt with a nut as the pivot
- A protractor fixed round the centre
- Thread with a bead as a plumb line
Safety: An adult must drill the pivot hole if a bolt is used.
Take it further: Add a vertical tangent line at x = 10 cm and extend the arm to meet it: the height where it meets is 10 times tan of the angle.
MathsEasy
Knotted 3-4-5 rope for making right angles like builders
Show detailsHide detailsWhat it shows
A rope with 13 knots at equal spacing is pulled into a triangle with sides of 3, 4 and 5 spaces. The angle between the 3 and 4 sides is exactly a right angle, because 3 squared plus 4 squared equals 5 squared, a trick used to lay out buildings for thousands of years.
You will need
- About 4 metres of thin rope or thick string
- A measuring tape
- Three pegs or three friends
- A set square to check
- Chalk to mark the ground
Safety: Peg the rope outdoors on soft ground, or hold it with fingers; never pull it tight near anyone's face.
Take it further: Use the rope to check whether the corners of your classroom are true right angles and report the error in centimetres.
MathsEasy
Measure a tree's height from shadows and similar triangles
Show detailsHide detailsWhat it shows
At the same moment the Sun makes the shadow of a tree and the shadow of a metre stick in the same proportion. If a 1 metre stick casts a 1.5 metre shadow and the tree casts a 9 metre shadow, the tree is 9 divided by 1.5, which is 6 metres tall.
You will need
- A metre stick or a straight pole of known length
- A measuring tape at least 10 metres long
- Chalk or pebbles to mark shadow tips
- A notebook and calculator
- A sunny morning or afternoon when shadows are long
Safety: Never look directly at the Sun. Measure shadows of trees from the ground only; do not climb.
Take it further: Measure the Sun's angle from the stick and shadow using tan, and compare with the angle you get from a clinometer.
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

- Write every observation in a notebook with the date
- 1 week before
Write the report and chart
- Aim, materials, method, observations, 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 on the card.
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.
Questions about science projects
Still have a question?
Chat on WhatsAppWhat 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.
