A drone is a small aircraft that flies without a pilot inside it. It is controlled remotely by a person on the ground or programmed to fly automatically.

The word drone began to be used for pilotless aircraft in the early 1900s. The name was inspired by male bees, also called drones, which do not gather food and were used as a metaphor for machines that operate without a human inside.

An elevator, or lift, is a big box large enough to fit several people in it that can go up and down inside a building. Elevators are used so people can get to higher floors in a building without having to climb up stairs.

An escalator is a set of moving stairs that is usually found in shopping centers or airports. They move so people don't need to climb up them.

A fan is something you hold in your hand, and you can wave it backwards and forwards to make a breeze of cool air over your face. This type of fan can be folded away so they are easy to store when you are not using them.

Fire hydrants are seen by the roadside in many cities. They connect to the mains water of that city and allow firefighters to tap into large amounts of high pressure water to put out fires. In some cities the fire hydrants are under the ground, with a small lid that needs to be opened before they can be used.
