How To
To build a barrier gate working model using a robo motor, car toy big wheel, paper straw (as the gate), and a 9V battery, follow these step-by-step instructions. This model demonstrates how barrier gates work, using basic materials and a DC motor to simulate the lifting and lowering of road gates at crossings or parking … Read more
A regenerative energy working model using two DC motors, a 9V battery, a switch, and toy car wheels can demonstrate how mechanical energy is converted into electrical energy and then reused. This model gives a practical demonstration of regenerative energy by recycling some of the energy from a mechanical system into electrical energy! Here’s how … Read more
A hydraulic lift working model using a syringe and cardboard is a fun and simple project to demonstrate the principles of hydraulics. The hydraulic lift model works on Pascal’s Law, which states that pressure applied to a fluid is transmitted equally in all directions. When you push the plunger of one syringe, it creates pressure … Read more
Creating a day and night working model for a science project exhibition that also shows the India and USA time zones is an engaging way to demonstrate how the Earth’s rotation affects daylight across different regions. The model can illustrate how different parts of the Earth experience day and night at the same time, depending … Read more
