Aldo stands next to a plant in a kitchen. He is in her mid-thirties, clean-shaven with curly hair. He wears glasses and a blue T-shirt with a print that reads "Home Work Zone."

He says HI I'M TEACHER ALDO
AND WELCOME
TO THE
HOMEWORK ZONE.
TODAY WE'RE HERE TO
TALK TO YOU
ABOUT PLANTS.
WHEN YOU THINK OF
PLANTS WHAT
COMES
TO MIND?
DO YOU THINK THAT
THEY HAVE
ROOTS OR MAYBE
SOME OF YOU WOULD
SAY THAT THEY HAVE
LEAVES OR STEMS -
SOME MIGHT
EVEN SAY THAT
PLANTS HAVE FLOWERS
BUT HOW MANY
OF YOU WOULD SAY
THAT PLANTS ARE GREEN?
FOR THE MOST PART
PLANTS ARE GREEN -
THE QUESTION
IS WHY?
THAT HAS
EVERYTHING TO DO
WITH SOMETHING CALLED
CHLOROPHYLL.
YOU SEE PLANTS
HAVE A PIGMENT IN
THEM CALLED
CHLOROPHYLL
AND CHLOROPHYLL'S
USED TO MAKE FOOD
FOR THE
PLANT.
CHLOROPHYLL
TRAPS SUNLIGHT RAYS
FROM THE SKY AND
THROUGH A
PROCESS OF
PHOTOSYNTHESIS
CREATES SUGAR AND
OXYGEN.

An animation shows the process explained.

He concludes I'M TEACHER ALDO
AND NOW YOU KNOW.
