IT IS FALL

Fall means shorter days and cooler nights.
Trees shed their leaves saying goodbye to summer
Trees that drop their leaves each fall are called
deciduous trees.
Why do you think dentists refer to baby teeth as
"deciduous teeth"?
Did you know that a tree's leaves are orange and
yellow -- even in summer? Most leaves include the
pigments of all three colors.
It's just that the pigment chlorophyll (the pigment
that makes the leaves green) is a much stronger
pigment than the others.
It covers the yellow (xanthophyll) and orange
(carotene) pigments that are natural to a tree's
leaves.
But, come fall, a tree's leaves produce less
chlorophyll. Now the other colors can show
through. And that they do -- in brilliant explosions
of color!
Another pigment (anthocyanin), which produces
reds and purples, isn't present all year long in most
green leaves. It only shows up as the nights get
cooler.
Butterfly
•
Fold flaps C & D to the front. Fold the outside edge
of each flap towards the center to allow the flaps to
lie down flat. (These are the back wings).

Origami butterfly

Before you start
It is important that you know how to do two
important folds that are referred to in the
instructions below:Instructions
Start with a (biggish) square of paper. Make a valley
fold horizontally across the paper. Then make
mountain folds along the diagonals. Corners A and E
will make the front wings, and C and D will be the
back ones.
•
Make a mountain fold at E. Then make a valley fold
to form a little point peeking up from behind your
model (This will be the head).
•
Fold the butterfly in half using a valley fold. Bringing
wing A to wing B so that the butterfly is side on.
•
Valley fold along wings A and C near the head to
make the body. Turn over your model and do the
same on the other side with wings B and D.
•
Bring corners A & C together. Then bring corners B
and D together. Tuck in the horizontal creases to
make a triangle shape.
•
I hope you now have a butterfly. If you pinch the
body the wings flap a little.
•
Fold down corners C & D to the right-angled point
of your triangle.
•
Why not color in or decorate the butterflies you've
made.
•
Make a valley fold across the triangle.
