Aldo stands 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 I HAVE A RIDDLE
FOR YOU:
WHAT'S GREEN
AND TALL AND
SOMETIMES SMALL AND
COVERED IN LEAVES?
IF YOU
SAID PLANTS YOU'RE
ABSOLUTELY
RIGHT.

The camera angle opens up and a plant appears next to him.

He continues THE QUESTION IS
WHY DO WE NEED PLANTS?
WE NEED PLANTS
BECAUSE THEY
CREATE OXYGEN
FOR THIS PLANET
AND ANY LIVING
CREATURE ON
THIS PLANET USES
OXYGEN TO SURVIVE.
THROUGH A PROCESS
OF PHOTOSYNTHESIS
PLANTS MAKE OXYGEN
FOR HUMAN BEINGS
TO BREATHE.

An animation shows the process explained.

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