What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. How does a thermostat know when to turn the heat on?

The Big Idea

A thermostat is like a little brain for your heating. It keeps your home at just the right temperature. How does it know when to switch on?

Sense the Room

Step one: sense the room. A thermostat senses the room's temperature. It turns the heating or cooling on or off.

Two Metals

Step two: two metals. Older thermostats use a coil of two different metals that bends as it warms or cools. The bending tilts a switch.

Smart Sensors

Step three: smart sensors. Newer ones use electronic sensors and can follow a schedule. Setting it a bit lower in winter when you are sleeping or away saves energy.

A Closer Look

Let's take a closer look! The sensor feels the room. The coil bends. The switch turns the heat on or off. A schedule saves energy.

Quick Facts

Quick facts! A smart thermostat can learn when your family is usually home. Older ones use two metals that bend as they warm or cool. Schedules can save energy. Setting it lower when you sleep or are away helps too.

Think Like a Scientist

Now, think like a scientist! Find the thermostat in your home. Ask a grown-up what it is set to. Check what the room thermometer says. Are the two numbers close? Then tell a friend what you found out.
