Every idea uses safe, everyday things. Steps marked "with an adult" involve heat, sharp tools or electricity from cells: do them only with an adult. Never use mains electricity or strong chemicals.

Class 8: models that move and microbes you can see working
By class 8, a project is expected to do more than show something: it should measure something. Teachers look for a clear question, a fair test and results in a table or graph. Many class 8 students also make a working model for a school science exhibition. The ideas above open on Class 8, with the projects that fit this year's topics first.
Projects that fit class 8 topics
- The invisible living world: the yeast balloon (yeast feeding on sugar gives off carbon dioxide), curd making at three temperatures, and bread mould in sealed bags.
- Magnetic and heating effects of current: an electromagnet whose strength you measure by counting pins picked up with 20 and 40 turns, and with one or two cells.
- Forces and friction: roll a toy car down a ramp onto the floor, a towel and newspaper, and compare the distances.
- Pressure: water that stays in an upside-down glass, and a hydraulic arm moved by syringes of water.
- Winds and storms: a paper-cup anemometer to compare wind at different places and times of day.
- Health and the body: the bottle-and-balloon lungs model, and heart rate before and after exercise.
- Static electricity: balloons that pick up paper, bend a stream of water and push each other apart.
Planning a working model
- Start from a question. "Does the number of turns change the strength of an electromagnet?" is better than "an electromagnet".
- List materials and test the idea small first. Make a rough version before the final one.
- Build it sturdy. Models get carried to school and handled by visitors. Use thick cardboard, a firm base and glue that has fully dried.
- Measure and record. Take three readings for each condition and use the average.
- Prepare a chart. Aim, labelled diagram, results table and a one-line conclusion are enough.
Safety for class 8
The electromagnet's wire and cell warm up if left connected, so connect them only while testing. Use only small cells; never mains power. For the hydraulic arm, use syringes without needles. Microbe projects need care: warm milk and lukewarm water should be prepared by an adult, nothing from the experiment should be eaten, and mould bags must stay sealed and go into the dustbin closed.
Your project file
Tap "Use in my report" on the project you choose. The report maker fills the introduction, aim, materials, procedure and precautions, and builds the cover, certificate, acknowledgement and index pages around them. After the experiment, type your observations and result, or leave them blank to write by hand on printed lines. The observations page also leaves a box for a photo of your model or a labelled diagram.

Frequently asked questions
What is an easy working model for class 8?
An electromagnet (a nail, copper wire and a cell), a hydraulic arm made with syringes and cardboard, a paper-cup anemometer or a bottle model of the lungs. Each needs a day or less and common materials.
Which class 8 project is about microorganisms?
The yeast balloon shows yeast giving off carbon dioxide, curd making shows how temperature affects helpful bacteria, and the bread mould project shows where fungi grow fastest. Keep the mould bags sealed.
Where do I get syringes for the hydraulic arm?
Ask a chemist for plastic syringes without needles, usually 10 ml. Never use a syringe that has a needle.
Can a class 8 project be used for a science exhibition?
Yes. Working models such as the electromagnet, hydraulic arm and anemometer suit exhibitions. Prepare a chart with the aim, a labelled diagram and the result, and practise explaining it in a minute.
How should I show results in a class 8 project?
Use a table and a graph. For the electromagnet, plot the number of turns against pins picked up; for the anemometer, plot turns per minute at different places or times.
