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.

Chapter Three Violet's PoV   About two hours later, Christina came up to wake me up “Violet,” She whispered “Violet” She said a little louder “Mhmm” “I told you I’d wake you up. I’m running to the store, do you want to come?” I sat up and nodded “Alright, get ready! We’ll leave in 15 minutes” I nodded again and got up just as she left the room. I went into the bathroom and brushed my hair, then changed into (INSERT PIC) I ran downstairs and saw Christina standing next to the door. We both walked out and got into the car “Are you feeling more rested?” She asked as we drove “Yeah, I little bit” “Good, because when I shop, I can get I bit crazy” She made a weird face and we both burst out laughing   She pulled into the parking lot and we both got out. We walked into the store and Christina handed me a list “Here, take this and go grab everything on it” I took the list and nodded “Alright!” Holding the shopping basket in one hand and the list in the other, I stared towards the food isles.   After grabbing most of the stuff on the list, I got to produce. I put some apples, oranges, and blueberries in the basket and moved on to the strawberries. Putting the best looking carton in my basket, I turned to continue hunting down everything on my list when I felt my foot slip out from under me. I let out a small squeal and reached out for something to steady myself with. To my horror, I grabbed onto the person standing next to me and pulled them down with me.  (OMG CLIFFHANGER  XD)

Chapter Two Violet's PoV                                              Violet’s PoV         “We will be landing in London is 10 minutes” I heard the pilot say over a loud speaker. I moaned and sat up. I must have fallen sleep and didn’t know it. I put my blanket and travel pillow back in my suitcase and waited for the plane to land   *Time slip to after the plane lands* I walked out of the boarding hallway and saw chairs, tourist and so many people they all looked like busy ants. An airport employee saw my and took me aside  “Are you waiting for someone to pick you up?” She asked, looking concerned. I nodded “Yes. My aunt should be here-“ “Violet!” As soon as I head my name, I spun around and saw my Aunt Cristina. Her long brown hair was in a messy bun and she was wearing a pink t shirt and some jeggings “Aunt Cristina !” I shouted as she hugged me The airline employee smiled “I’m guessing she’s your aunt” I nodded “Alright. Take care” She smiled at me once more then went back to work. Aunt  Cristina waved me to follow her “So kiddo, how was your plane ride?” She asked me using her British accent. I mean, she had moved to England a year ago, so her accent was almost flawless. I giggled “It was great! I slept through most of it though” “Hey, it happens! Time zones are tricky things” She chuckled when I yawned “What time is it?” “Where? Here or in Long Island?” “…Here.”   “Uhh.” Aunt Cristina took out her phone and checked the time “its 7 am” “Whooooa. No way…” I yawned again. “Yup, but to you it feels like…” She paused and it seemed she was doing some quick math in her head “2 am” I groaned “How long till I get used to the time zones?” “I’m guessing less than a week” “Alright…that’s not that bad” By this time, we had gotten to her car. I giggled “It’s backwards” I told her as I sat in the front seat, which in America would be the drives seat  Cristina chuckled “To you it is. To me it’s not, well, not anymore. It took a while to get used to. A long while” I nodded “I can see how.” I was silent as she started the drive back to her house. Out the window I saw Big Ben. I snapped a picture of it for Rachael. I was about to text it to her when I remember the time zones. I decided I would send it….tomorrow? Or whenever it wasn’t too early for her. And then it hit me “OH MY GOD!”  I practically yelled as I looked at the picture I took “What?”  Cristina asked me in shock “N-nothing, just a inside joke” I told her through my laughter. That’s where Max and Harvey filmed most of the Stitches and Treat you Better mashup!! “If you say so…” She said laughing along with me. I turned and looked out the window but before I knew it my eyes were getting heavy. I leaned by in my seat and closed them. The sweet smell of Cristina’s perfume made me feel more comfortable as I drifted off to sleep   *Time slip to after the car ride* Cristina pulled into her driveway and I was bouncing in my seat “Chill out kiddo! You have all summer to explore!” “I know, I know!” Cristina just chuckled and stepped out of the car. I did the same and followed her into the house. She put her keys on the kitchen table then sat down “Your room is all set up. It’s upstairs and the first door on the left” “Thanks!” I yawned again “I think I’m going to go get some sleep” “Ok! I’ll wake you up in a little bit” I smiled and made my way upstairs. I found my room and walked in. The room was a beautiful light pink and the bed was made with white bedding. I laid down and fell asleep almost instantly.

We need to be taking a stand to save the remnants of our culture, before they disappear. If technology can improve health care, life for people with disabilities, ensure safety, or reverse global warming, then I'm all for it. Otherwise, we need to limit it. But how does online shopping turn one into a computer?
