A propeller boat works by spinning paddles attached to a rotating axle, creating thrust in water. To make one, first, paste ice cream sticks in a boat-like structure and make holes to insert axles. Attach bottle caps with slits as paddles to the axles. Secure a rubber band to the boat’s tip and axleRead more
A propeller boat works by spinning paddles attached to a rotating axle, creating thrust in water. To make one, first, paste ice cream sticks in a boat-like structure and make holes to insert axles. Attach bottle caps with slits as paddles to the axles. Secure a rubber band to the boat’s tip and axle for propulsion. Wind the rubber band, release it, and watch the boat move in water.
The wheel and axle system reduces friction, allowing smoother movement for loads. To make a rubber band car, create a frame using clothes clips. Attach bottle caps as wheels using chopsticks and glue. Secure a rubber band between the back wheels and frame for propulsion. Wind the rubber band and relRead more
The wheel and axle system reduces friction, allowing smoother movement for loads. To make a rubber band car, create a frame using clothes clips. Attach bottle caps as wheels using chopsticks and glue. Secure a rubber band between the back wheels and frame for propulsion. Wind the rubber band and release it to power the car forward. This simple mechanism demonstrates the practical application of the wheel-and-axle principle.
To make an air balloon car, gather materials: a plastic bottle, flexible straw, balloon, bottle caps, chopsticks, tape, and glue. Tape the chopsticks onto the bottle as axles and attach bottle caps as wheels. Insert a flexible straw through a hole in the bottle and secure a balloon to its end usingRead more

Tape the chopsticks onto the bottle as axles and attach bottle caps as wheels. Insert a flexible straw through a hole in the bottle and secure a balloon to its end using a rubber band. Inflate the balloon, place the car on a flat surface, and release the air to propel it forward.
To create a windmill, first, build a cardboard box as the base frame. Pierce holes in the sides to insert a straw as the axle. Attach circular cardboard pieces and paper blades to the axle for rotation. Assemble the parts and ensure free movement of the blades. When exposed to wind, the blades rotatRead more

Attach circular cardboard pieces and paper blades to the axle for rotation. Assemble the parts and ensure free movement of the blades. When exposed to wind, the blades rotate, demonstrating how wind energy can be converted into mechanical energy, simulating a real windmill.
A bicycle consists of several main parts: the frame provides structural support; wheels enable movement; pedals transfer force from the rider's feet; chains connect the pedals to the wheels, creating motion; and brakes slow or stop the bicycle for safety. Additional parts include handlebars for steeRead more
A bicycle consists of several main parts: the frame provides structural support; wheels enable movement; pedals transfer force from the rider’s feet; chains connect the pedals to the wheels, creating motion; and brakes slow or stop the bicycle for safety. Additional parts include handlebars for steering, tyres for traction, and spokes for stability. Together, these components work harmoniously to transform rider effort into motion, ensuring efficiency and safety.
