How Does Negative Feedback VS. Positive Feedback Explained w/ Examples Work?

Imagine you're trying to stay at just the right temperature, not too hot, not too cold, and someone is helping you keep it that way, either by making things cooler or warmer as needed.

Negative feedback is like a helpful friend who notices when you're getting too warm and turns on the air conditioner to cool you down. Or if you're too cold, they turn on the heater. This keeps everything balanced, just like how your body keeps its temperature steady even when you run around outside.

Positive feedback, on the other hand, is more like a friend who sees you getting warmer and turns up the heat to make it even hotter! It’s like when you're on a swing, if you pump your legs harder each time, you go higher and higher. It makes things go further in the same direction.

Real-life examples

  • A thermostat is an example of negative feedback, it keeps the room at a set temperature.
  • A barking dog that wakes up more dogs is like positive feedback, the noise gets louder and louder! Imagine you're trying to stay at just the right temperature, not too hot, not too cold, and someone is helping you keep it that way, either by making things cooler or warmer as needed.
