Why Do Leaves Change Color?

The arrival of fall brings cool new back-to-school clothes, the return of football and hockey and beautiful chameleon leaves. Are trees as fashion conscious as the celebs or is there more to this color change? Kidzworld finds out!


Autumn Leaves - Photosynthesis

Photosynthesis is the process of turning light energy into chemical energy by storing it as sugar. During the spring and summer, trees can make plenty of food because of the long hours of daylight. The process of photosynthesis takes place in the chloroplasts (food making centers), specifically using chlorophyll (the green pigment involved in photosynthesis).


Autumn Leaves - Goodbye Green Trees

During winter, there's not enough water or light for photosynthesis to take place. The trees have to live off the food they stored during the summer. The food-making factories start shutting down and the green chlorophyll disappears from the leaves. When the bright green fades away, the yellow and orange colors - that have always been underneath - begin to show. They've been there all along they've just been covered up by the green chlorophyll. Eventually even those colors fade and the brown leaves start to drop off.


Autumn Leaves - Did U Know?

  • The best places to see vibrant autumn leaves are in the eastern United States and in southeastern Canada.
  • One large tree can lift up to 100 gallons of water out of the ground and discharge it into the air in one day.
  • Trees first appeared on Earth long before the dinosaurs did - about 400 million years ago.
  • Trees combat the greenhouse effect and slow the effects of global warming. They soak up carbon dioxide and exhale oxygen for us to breath.

I found the greatest riddle ever (credits to Ted-Ed), and I want to see if anyone can solve it without looking up the answer. THE RIDDLE OF THE ALIEN OVERLORDS. You and your team have crashed-landed on an ancient planet. The only way off is to appease its three alien overlords, TEE, EFF, and ARR, by giving them the correct artifacts. Unfortunately, you don't know who is who. From an inscription, you learn that you may ask three yes or no questions, each addresses to any one lord. Tee's answers are always true. Eff's answers are always false.  And Arr's answers are random. But, there's a problem. You've deciphered the language enough to ask any question, but you don't know which of the two words 'ozo' and 'ulu' means yes, and which means no. How can you still figure out which alien is which?

Fear: The Emotion of Death   You can't see me, But I'm there. I'm in your tears, I'm everywhere. I stalk you in your shadow, So stealthy and no slack. I'm made of dark matter, You better watch your back. You can hear me, I'm your beating heart. Inside is emptiness, Tearing you apart. You shiver and shake, At the sound of my name. I engulf you, drown you, Surround you with shame.   I've seen destruction, More than anyone. I'm darker than, The world with no sun. The agony arises, There's so much red. Most of it coming, From the dead. I become your shadow, I'm a terrible sight. And when you see me, You're frozen with fright. I'll grab you by your neck, You'll be thrashing around. You're crying, shrieking, Until there's no sound.   I feel so sad, So empty, so. . . Alone. So you'll feel the same, You'll be on your own. And as long as you are with me, At the point of no return. You will go crazy. You'll crash and burn.   Then you understand, With your slowing of breath. That I am Fear, The Emotion of Death.
