Educational content slides
Your body maintains 98.6°F without you thinking about it.
Too cold? Shiver to generate heat.
Too hot? Sweat to cool down.
Your brain constantly checks temperature and adjusts. That's a feedback loop: sense → decide → act → sense again.
Every thermostat, cruise control, and even YouTube's recommendation algorithm works the same way.
Test your understanding with this quiz.
Your shower oscillates between freezing and scalding. What's the actual problem in the feedback loop?
