Autumn Leaves… an Alien Message? Cont.

Dude! Did you look at that article at You know, the big problem with these science stuff is the long words. Like “pigments.” What’s that? Mr. W says it’s what makes something a particular color. So why don’t they just say “colors”?

Anyway, I guess my idea about trees being aliens is bust. I looked over that article, and if you remember, I had two questions…

What makes tree leaves change color?

I guess trees start out with stuff that colors them, that pigment stuff. And “chlorophyll” is what makes them green. (I thought chlorophyll was what they call the pool guy, Phil, who puts chlorine in the pool…) Anyway, chlorophyll takes light and makes it into food for the plants. Kewl!

Then, there’s something else in leaves called “auxin.” (Hmmmm… sounds like an alien name to me…) This stuff keeps the channels to the leaf open… I think of it kind of like keeping blood vessels open. You know how leaves got little lines in them? Like little blood vessels, right? Except with no blood… weird. So, I guess auxin keeps those things open so the leaf stays connected to the tree.

When the tree stops making auxin, everything closes off, and it doesn’t get any food. Then the chlorophyll dies… and the green goes away. Then, you can see the other colors from other pigments in the leaves.

Why does it happen in the fall?

I guess all this stuff happens when it gets cold and the days get short… but how does that stop the auxin? The article doesn’t say. Maybe it is aliens after all…

What do you think?

Autumn Leaves… an Alien Message?

You are traveling to another dimension… a dimension not of sight and sound, but of mind… next stop… Dwayne’s Twilight Zone… doo, doo, doo, doo… doo, doo, doo, doo…

Seriously. Did you know science was so freaky? I never thought of it until I started studying for my GED. So I decided to keep you up to date on the weird and wild world of science…

Like, I was looking out my window, and I noticed that the leaves on the trees are starting to change colors. They do that every year, yeah, sure… but how come? I started to think how the trees are probably really aliens who traveled to Earth millions of years ago, and have been quietly waiting for the right moment to take over! And changing the colors of their leaves is a secret signal to each other and to their master ship that’s rotating the Earth.

Okay, Curtis says when I get ideas like that in my head, I should look up what’s really true. So I decided to look up about leaves. First I thought up my questions.

  • What makes tree leaves change color?
  • Why does it happen in the fall?

Here’s a link I found to start looking up my answers:

What do you all think? Are autumn leaves a natural process? Or signs of alien communication?

I’ll let you know next time what I found out.

GED Science: Corpse Flowers…. Ew! Yuck!

Kewl… zombie flowers! Who knew? The GED Science test’s got ‘life science’ questions on it… and that means questions about all the kewl plants and animals and stuff… oh, yeah, and people too. And here’s one of my favorites! The GIANT, STINKY CORPSE FLOWER! It’s totally for real… a giant, stinky flower! Continue reading
