Welcome to our exciting adventure into the world of shadows!

Today we're going to explore what shadows are and how they form.

Have you ever noticed your shadow following you around on a sunny day?

Shadows are made when an object blocks light.

See how the shadow appears on the ground behind the person?

That's because their body is stopping the light from reaching that spot.

Shadows are like silhouettes of objects!

A silhouette is an outline of something, usually filled in, in black and on a white background.

Did you know that shadows change throughout the day?

That's because the position of the sun changes as it moves across the sky.

In the early morning and late afternoon, shadows are long because the sun is low.

But at midday, when the sun is high, shadows are short!

Shadows can be cast by all sorts of things, like trees, buildings, and even clouds!

Anything that blocks light creates a shadow.

You can even make shadows with a lamp in your house.

Why don't you give it a try?

So, next time you're outside on a sunny day, take a moment to look at the shadows around you.

See you next time. Goodbye.
