Troy stands next to a gray chalkboard showing math signs, different coins and colourful logo that reads "TVOKids Home Work Zone." He is in her early thirties, clean-shaven and bald. He wears a blue T-shirt and a watch.

He says HEY GUYS, IT'S
TEACHER TROY HERE.
DO YOU NEED HELP MEASURING?
TODAY, WE'RE GONNA BE TALKING
ABOUT MEASURING WEIGHTS.
YOU'RE MEASURING WEIGHTS, WE
HAVE TO DEAL WITH DIFFERENT
UNITS OF MEASURE.
SO WE'LL TALK ABOUT GRAMS AND
KILOGRAMS AND WE'LL TALK ABOUT
GRAMS AND KILOGRAMS, WHAT'S THE
DIFFERENCE AND THE DIFFERENCE IS
REALLY, REALLY BIG.
FOR EXAMPLE, RIGHT HERE WE HAVE
A SALT SHAKER.
IF I TAKE THAT AND SPRINKLE IT
ON MY HAND, I NOW HAVE SALT ON
MY HAND.
HOW MUCH DOES THAT WEIGH?
THAT'S ABOUT...
LESS THAN ONE GRAM OF SALT THAT
I'VE JUST PLACED ON MY HAND AND
AS YOU CAN SEE, IT'S VERY, VERY,
VERY SMALL.
SO, JUST TO GIVE YOU A RECAP,
GRAMS ARE USED TO MEASURE THINGS
THAT ARE VERY SMALL.
SO, WE'RE TALKING ABOUT SALT,
WHICH IS VERY SMALL, WE USE
GRAMS.
AND WHEN WE'RE WRITING THAT ON
THE BOARD...

Using white chalk, he writes "1 g."

He continues THAT WOULD BE ONE GRAM.
SO, ONE GRAM IS APPROXIMATELY
THE WEIGHT OF, SAY...
50 LITTLE CUBES OF SALT.
VERY SMALL.
NOW, WHEN WE WANNA MEASURE
SOMEONE LIKE ME, YOU'RE NOT
GONNA MEASURE ME IN GRAMS
BECAUSE I'M REALLY BIG.
SO, YOU HAVE ANOTHER UNIT THAT'S
CALLED KILOGRAMS AND WE'RE
DEALING WITH KILOGRAMS, A
KILOGRAM, ONE KILOGRAM IS EQUAL
TO 1,000 GRAMS.
SO, AS YOU CAN SEE, THE
DIFFERENCE BETWEEN A GRAM AND A
KILOGRAM IS VERY, VERY LARGE.
SO, DO YOU WANT A SMALL BIT TO
MEASURE ME OR DO YOU WANT A
BIGGER UNIT TO HELP MEASURE ME?
I WEIGHT APPROXIMATELY 100
KILOGRAMS, SO YOU CAN ONLY
IMAGINE THAT, THAT'S PRETTY BIG
SO THAT'S DEALING WITH 100,000
OF THESE, SO THAT'S A LOT OF
SALT TO GIVE YOU AN EXAMPLE.
SO, JUST TO GIVE YOU AN IDEA
WHEN YOU'RE MEASURING, YOU
ALWAYS USE GRAMS FOR THINGS THAT
ARE VERY SMALL, KILOGRAMS FOR
THINGS THAT ARE LARGER AND WE
HAVE OTHER UNITS THAT MEASURE
BIG, BIG THINGS LIKE TANKS AND
MONSTERS AND STUFF LIKE THAT BUT
WHAT WE'LL DO IS WE'LL STICK
WITH OUR GRAMS AND KILOGRAMS FOR
TODAY.
I'M TEACHER TROY AND I HOPE THAT
HELPS.
