He says HI I'M TEACHER
ALDO AND
WELCOME TO
THE HOMEWORK ZONE.
TODAY I'M HERE TO
TALK TO YOU
ABOUT
SIMPLE MACHINES.
IF YOU TAKE A LOOK
AROUND YOUR
HOME THERE ARE
MANY EXAMPLES OF
SIMPLE MACHINES;
YOUR BICYCLE
FOR EXAMPLE IS
A SIMPLE MACHINE
BECAUSE IT
HAS GEARS.
THE SHOVEL THAT
YOU USE TO
CLEAN YOUR
DRIVEWAY IS A SIMPLE
MACHINE BECAUSE
IT'S A LEVER.
SIMPLE
MACHINES ARE AMAZING
TO HUMAN BEINGS
BECAUSE THEY
HELP US DO WORK
AND THEY HELP US DO
IT IN LESS TIME;
THAT'S WHY WE
NEED SIMPLE
MACHINES IN OUR WORLD.
TAKE A LOOK AROUND
YOUR HOME FOR
MORE EXAMPLES
OF SIMPLE MACHINES;
I'M TEACHER ALDO AND
NOW YOU KNOW.
