Changing of the'Leaves

I love autumn! I love the blue skies. This year we are going to Mt. Sorak to see the colorful leaves on the trees!

What are you doing? We're leaving soon. I don't want to go. Can Bada and I stay here? We don't want to go hiking. No, you can't. Besides, I know you'll love Mount Sorak. Now, come on!

Wow! Look at the beautiful colors! Why do leaves change colors? Because the trees are getting ready for winter.

All leaves have green, yellow, and orange in them. But in the summer, the green color is the strongest. Why?

Because of the sun, and water from the tree. But when the weather gets cooler, the tree gets less sun and water.

So the green fades, and the other colors like yellow and orange become brighter.
