Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why should you never play with a magnifying glass in the sun?

The Big Idea

A magnifying glass can gather sunlight into one small, very bright, very hot spot. That spot can scorch paper, leaves, and skin, and it can even start a fire. That is why a magnifier is never a toy to use in the sun.

Gathering Light

Step one: gathering light. A magnifier bends the sunlight that hits the whole glass. It squeezes all of it into a tiny spot.

Hot Spot

Step two: the hot spot. Sunlight carries heat energy, and the lens piles it up in one place. That spot can scorch paper, leaves, and skin.

Stay Safe

Step three: stay safe. Never point a lens at the Sun, a person, or an animal, and never look at the Sun through any lens. Use a magnifier only indoors, and keep it in a case.

A Closer Look

Let's take a closer look! A magnifier can focus sunlight. Keep lenses away from sunny windowsills. Clear glass balls and water bottles can focus sunlight too. Store lenses in a case, out of the light.

Quick Facts

Quick facts! Sunlight can start a fire when it is focused. Your eyes can be hurt by looking at the Sun, even for a short time. Round glass objects and full water bottles can work like lenses. Always ask a grown-up where to store lenses.

Think Like a Scientist

Now, think like a scientist! Use a magnifier only indoors, to look at things like a leaf or a coin. Always point it away from windows and the Sun. Keep it in a case when you finish. Then ask a grown-up where lenses should be stored.

Outro

Magnifiers are safe indoors, but never in the sun. Science is amazing! Crafty Clover can be found on Amazon Books, Google Bookstore, and Apple Books. Available for purchase or download! Bye for now!
