BUM BUM! BUM BUM! IT'S SO SWINTER!!!!!!!!!!! Oh hey guys! I was just watching Phineas and Ferb. Does anyone else wonder when they are going back to school?! Anyways, they were singing a song called Swinter. It was about winter in summer. They made a winter-maker-thingy in summer and called it Swinter...or Wummer. Well, what I hadn't notice before was that it has a secret scientific message. How come I always get blog topics from cartoons? Weird... Anyways, today we'll me talking about autumn!
It seems so peaceful! |
So what's your favorite thing about fall? Is it the beautiful weather? I love the weather outside! Not to hot, not to cold. Ever wonder why it always changes? Why do we have season and why does each season have a different climate? Well it's simple. Earth is tilting on its axis. If it tilts away from the sun, then it's winter. If it tilts closer to the sun, then it's summer. Also, since the earth tilts diagonally when it's summer in the Northern Hemisphere (aka us) then it's winter in the Southern Hemisphere.
What else do you love about fall? How about the pretty colors on the leaves? Have you ever wondered why they change colors? Well, they actually never "change" they were always there but couldn't be couldn't be seen because of the chlorophyll. What is chlorophyll you ask? It's this thing inside leaves that takes sunlight and makes it into food and energy. This causes the green color in leaves. In fall and winter we get less hours of daylight, which means less sun. Since it doesn't have enough sunlight the chlorophyll dies and goes away.
The colors underneath the chlorophyll go into two different groups. There are carotenoids which have yellow, orange, and brown colors and anthocyanins which have red, purple, and pink colors. As the chlorophyll dies out, those colors finally get a chance to shine! Yay for the colors! Eventually, the leaves all fall off and decompose into the soil.
This is so pretty! |
