Vehicles

A fire engine, fire truck, or fire appliance is a vehicle especially designed for putting out fires. Fire trucks usually carry hoses, cutting equipment, ladders, fire extinguishers and other general tools. Some fire trucks have a water supply as well, most have a powerful pump that can draw water from a fire hydrant.

A glider is a type of aircraft that doesn't have engines. Gliders are usually towed up into the air by another plane and can glide a very long way before they reach the ground.
Some gliders, called motor gliders have small engines for takeoff and to keep them in the air longer.

Hang gliding is a sport where people glide through the air hanging from a set of light fabric wings. Hang gliders are usually launched off high, windy places like cliffs.

A helicopter is a type of aircraft that is lifted by one or more rotors on its top. Helicopters have another small rotor on their tail for balance and steering.
Normal airplanes get their lift from air flowing over their wings. Because helicopters get their lift from the rotating blades on their top, they don't need a runway to take off, and can just go straight up from a standing start. They can also turn around on the spot while they are in the air.

Hovercraft are vehicles that are supported by a cushion of air, and move forward by fans or propellers. They have fans that push air underneath them, and the air cushion is held in place by a flexible skirt around the base of the hovercraft. Hovercraft can travel over any relatively flat surface, like water, ice, swamp and dry land.

A jet is the common name given to any airplane that is powered by jet engines rather than propellers. Most modern aircraft are powered by jet engines, so people tend to refer to smaller, faster military aircraft as jets.

A monorail is similar to a train in that it travels along a fixed track. The main difference is a monorail has only one track, not two like regular trains. Some kinds of monorail hover above their track (also called a rail or beam). These are called maglev monorails.
Many monorails travel on raised tracks above a city. Not all monorails are raised like this. The beams a monorail travels on are large and solid and are often cast out of concrete, like the raised platform itself.

A paddle steamer, or paddle wheeler, is a type of boat that is driven forward by a large wheel. Usually the wheel is at the back of the paddle steamer (stern-wheeler), but there can also be a wheel on either side (side-wheeler).
Paddle steamers are usually found on still, calm water like rivers. The paddle wheel can be driven by either a steam engine or a more modern electric or diesel engine.

A pram is a small vehicle you put a baby inside and push them along. Prams usually have a hood on top to keep off the sun and rain.

A rocket is a long, tube-shaped vehicle that forces hot gas out one end when it is launched. Rockets can go extremely fast, and can be used for a variety of purposes.
