Top 10 Best Working Model of Science Exhibition for class 8, 9 and 10

Making a working model of a science project which is just a visual demonstration of some scientific principles is boring. So what the most creative and fun factor way? how we can bring new excitement and enthusiasm to a science exhibition’s project? the answer is to make those project that has working parts or aspects that can make the scientific principle in question come alive and be a much more effective tool.

Here is some most popular working model of science projects which have published on the PSC science portal paksc.prg/pk/science

10. Working Model of Science Project Water level Indicator

we can use the Water level indicator to show how water can complete a circuit. It is a good conductor of electricity. It is a very interesting DIY Physics project. Definitely a great idea to show the working of sensors and alarms. If you want to build your own model for a science activity workshop,  kitchen or garden, this is the right project. In this project, students can show the audience about conductors, non-conductors, series circuits, electricity, and application. Make it

9. Working Model of Science Project “Capacitor”

 A capacitor is a device for storing a small electric charge. When two conductive plates separated by a small insulator called a dielectric, they produce an electric field. Aluminum foil is conductive while cling wrap is insulating. Both are flat, thin, and ideal materials for building a do-it-yourself capacitor. In this working model, students can prove concepts of capacitance, working, and applications. Make Capacitor

Cotton candy has special fame at a worldwide level. it is one of the oldest and popularized thing among all. kids love it more than elders. We can make a cotton candy machine at home by using simple household material.

When the sugar heated, it becomes liquid caramel and then burns out if heating continues. if liquid caramel is pushed out from tiny holes to the outside by the centrifugal force when the container continuously rotates, the cotton candy is produced by the recrystallization of it in the form of minutely thin sugar strands. Try To build a cotton candy machine

4. Working Model science project “water rocket”

Making of biogas plant

Our all-time favorite and the most popular project among students is making of the biogas plant. The purpose of this project is to discover different ways to produce Biogas through alternate sources by using our local resources. It can help students to show the basics of Anaerobic digestion and the production of gas by different organic kitchen wastage. The basic task is to design, make, test a simple waste digester and gas collection system. One can check various facts of the anaerobic digestion process. It has been popular as a source of energy for over 200 years. Make your own number one science fair project biogas plant
