Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why are smoke detectors better than noses alone?

The Big Idea

Smoke detectors are better than noses alone because your nose does not wake you up well when you are asleep. You might sleep right through an early smoke smell. A smoke detector keeps listening all night and sounds a loud alarm.

Sleeping Nose

Step one: a sleeping nose. When you are asleep, your brain pays much less attention to smells. So a smoky smell may not wake you up in time.

Loud Alarm

Step two: the loud alarm. A smoke detector senses smoke particles in the air all day and all night. When it notices smoke, it makes a very loud sound that can wake you up.

Escape Plan

Step three: act fast. If a smoke alarm goes off, get out of the house, stay out, and let a grown-up call 911. Your family should practice a plan with two ways out.

A Closer Look

Let's take a closer look at staying safe! While you are asleep, your nose is not much help. The detector sounds a loud alarm. You and your family get out quickly. And a grown-up calls 911 from outside.

Quick Facts

Quick facts! Smoke detectors have batteries or are wired into the house. Grown-ups should test them on a schedule, usually every month. Detectors should be on every floor and near sleeping areas. Never hide under a bed or go back inside during a fire.

Think Like a Scientist

Now, think like a scientist! With a grown-up, test your smoke detectors on schedule. Listen to the beep so you know what it sounds like. Then practice your family escape plan!

Outro

Smoke detectors are great backups for your nose. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
