Barometer

Real World Example

Imagine you're trying to figure out if it’s going to rain by looking at the sky. Just like how clouds in the sky can give you clues about upcoming weather, a barometer provides information about air pressure, which is a key indicator of weather changes. The way clouds signal potential rain is similar to how a barometer measures air pressure changes to predict weather patterns; both are tools that interpret environmental cues to forecast what might happen next.
