science working model
This is a working model of the human respiratory system.The plastic bottle represents the chest cavity.The two balloons inside are our lungs, and the straws act as the trachea and bronchi.The balloon at the bottom represents the diaphragm, which plays a key role in breathing. When we pull the bottom balloon (diaphragm) downward using the … Read more

LEDs (Light Emitting Diodes) are small electronic components that glow when electric current passes through them. To connect three LEDs in parallel using a 9V battery, switch, and resistors, we follow a simple circuit design. Here’s a simple step-by-step guide to connect 3 LEDs in parallel with a 9V battery, switch, and resistors You Will … Read more
Energy is the ability to do work, and it exists in many forms. Light, wind, and sound energy are three common types we use in daily life. Light energy comes from sources like the Sun, bulbs, and lamps. It helps us see, grow plants (through photosynthesis), and even generate electricity using solar panels. Wind energy … Read more
This model demonstrates how wind energy can be converted into electrical energy using a wind turbine connected to a DC motor, which powers an LED bulb to light up a cardboard house. This model shows how wind energy is converted into electrical energy using a wind turbine connected to a DC motor. The electricity powers … Read more
