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
8. Make your own Biodiesel
Biodiesel بائیو ڈیزل made from a vegetable oil or animal fat-based diesel fuel consisting of long-chain alkyl and esters. Biodiesel is normally made by chemically reacting lipids e.g., vegetable oil, an animal with alcohol produces fatty acid esters. This project is related to renewable energy physics, biology. Make Biodiesel
7. Working model of science project "astronomical telescope"
Telescope دوربین an optical instrument designed to make distant objects seem nearer containing an arrangement of lenses, or of curved mirrors, which rays of light are collected and focused and the resulting image magnified. In this video tutorial, you can make your own simple telescope with simple and cheap materials.
6. Make a solar cell
A solar cell is a device for converting energy from the sun into electricity. The high-efficiency solar cells you can buy at Radio Shack and other stores are made from highly processed silicon and require huge factories, high temperatures, vacuum equipment, and lots of money. Visit Make Solar Cell
5. Working model of science project "cotton candy machine"
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"
To make a water rocket is one of the practical demonstrations of construction and working of rockets. Anyone can make their own water rocket by using simple household material like plastic bottles, electrical tape, polythene bags, etc. It is an interesting project and explains the working and aerodynamics of a rocket that uses pressurized air and water as fuel. See Construction of Water Rocket for Competition
3. Working Model of science project "wind turbine"
Using a few common things, you can make a working wind turbine. it is a very interesting and simple project. If students are keen enough you can even start producing electricity with it. Learn how you can build the windmill
2. Working Model of Heart
This is the 2nd most popular science project on our list which is related to biology. If you're looking for a cool, cheap science fair project, make a working model of the human heart. This project doesn't require a long list of materials. You can make it by using physioball, PVC Pipe cap, balloons, and drip pipe. you can easily complete this project in an hour or so. This working model of heart project is sure to impress your teachers and classmates. Learn how to build
1. 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
Update 7th October 2020: Now Working model of the heart is # 1 project
