Transcript: Student Session 18 | Aug 24, 1998

(music plays)

A blue slate appears with the title “Agenda.” It shows a numbered list “1. Dawson City, Yukon. 2. Math Lesson. 3. Homework.”
The slate changes. It’s now reads “To log on: Pick up handset, press pound. Key in I.D. number, then pound. Press 1 to confirm. Hang up” and shows a timer from 2 minutes.
At the 1 minute mark the slate changes. It reads “TVO’s Virtual Classroom. Get connected.”
The “V” in “Virtual” is a tick, the “A” in “classroom” is an at sign with an extended loop that turns into a power cord with a plug at the end, and the first “O” in “classroom” is a spinning globe.

Stewart sits in the studio. He’s in his forties, with a brown beard and wavy brown hair. He’s wearing a brown cowboy hat, plaid blue, white and red shirt, and yellow suspenders.
He has a wok in his hands and is moving it back and forth.
[clanging]

Lorraine walks in and sits next to Stewart. She’s in her forties, has long red hair tied back and a beauty mark on her cheek. She’s wearing a white dress and a white wig with flowers.

Stewart says DON'T TELL ME THEY
ASKED YOU, TOO?

Lorraine asks WHO ASKED ME WHAT?

Stewart says THE LOCAL THEATRE GROUP
TO BE PART OF THE PLAY TO
COMMEMORATE THE 100th
ANNIVERSARY OF THE KLONDIKE
GOLD RUSH.

Lorraine says WELL, YES, AS A MATTER
OF FACT, THEY DID.
AND WHY WOULDN'T THEY?
YOU KNOW, I'M A DEAD RINGER
FOR DIAMOND TOOTH GERTIE,
WHO WAS THE STAR OF THE RED
FEATHER SALOON IN DAWSON CITY.

Stewart says WELL, I'M CARMACK JIM.
AND HE WAS ONE OF THE FIRST TO
DISCOVER GOLD IN THE KLONDIKE.

Lorraine says WELL, IT'S EASY TO SEE WHY
THEY PICKED YOU, Mr. C.
YOU DARN LOOK A HUNDRED
YEARS OLD, ANYWAY.

Stewart says WELL, YOU'RE NO
SPRING CHICKEN MYSELF.

Lorraine says WELL, I GUESS I DESERVE THAT.
ANYWAY, WHY DON'T WE PRACTICE
OUR LINES FOR THE SHOW?

Stewart says SURE.

Lorraine says ALL RIGHT.
AHEM.
HAD ANY LUCK PANNING FOR
GOLD NEAR THE CREEK TODAY,
CARMACK?

Stewart takes a gold nugget out of the wok.

He says RECKON I DID,
MISS DIAMOND TOOTH.
GOT ME THIS BEAUTIFUL NUGGET.
YOU KNOW, A MAN GETS DARN
THIRSTY DOWN THERE BY THE
CREEK WORKING ALL DAY.
I THINK I'M GONNA MOSEY ON
OVER THERE AND GET ME A
SARSAPARILLA IN A DIRTY GLASS.
I SAID, I'M GONNA MOSEY
ON OVER THERE AND GET A
SARSAPARILLA IN A DIRTY GLASS.
AHEM!
AHEM!

Lorraine says OH, IT'S MY TURN.
OH, GUESS I'M NOT READY FOR
MY NORTH AMERICAN DEBUT.
WELL, HOPEFULLY THE STUDENTS
AT JACK MINER, YOU'RE MORE
PREPARED THAN I AM, SO GIVE
US A CALL BY PRESSING POUND
NINE, AND SHARE WITH US THE
INFORMATION YOU HAVE ABOUT
DAWSON CITY.
SO JACK MINER STUDENTS, CALL
US NOW BY PRESSING POUND NINE.
AND WE DO HAVE
OUR STUDENTS HERE.
AND WE'LL START WITH CRYSTAL.

Stewart says OH, BOY.
I'M LOOKING FORWARD
TO THIS INFORMATION.

Lorraine says SO AM I.

Stewart asks IS CRYSTAL THERE?

Lorraine says YES, HELLO?

Crystal says HELLO?

Lorraine says HI.
WHAT DO YOU HAVE
ABOUT DAWSON CITY?

Crystal says I HAD THE POPULATION.

Lorraine says OKAY, GREAT.
POPULATION.
THE VOICE CHANGED.
AND LET'S SEE HERE.
WHAT DO YOU HAVE
FOR POPULATION?

Crystal says IN 1898, WHEN THE GOLD RUSH
WAS HAPPENING, THE POPULATION
WAS 30,000.

Stewart writes the information in a piece of paper.

Lorraine says EXCELLENT.

Stewart asks DO YOU KNOW
TODAY'S POPULATION?

Crystal says YEAH, 972.

Stewart says 972 IN 1998.
BOY.
A HUNDRED YEARS LATER.
WHAT ELSE HAVE WE GOT?

Lorraine asks ANY MORE INFORMATION?

A student says YEAH, I HAVE THE AREA.
THE AREA IS 483,450
SQUARE KILOMETRES.

Stewart asks FOR ALL OF THE YUKON, RIGHT?

The student says YEAH.

Stewart says OKAY, GREAT.

The student says I HAVE THE FAMOUS LANDMARKS.

Stewart says OKAY, GOING FOR LANDMARKS.
WHAT YOU GOT?

The student says OKAY, THE WHOLE TOWN IS A
FAMOUS LANDMARK BECAUSE OF THE
1898 KLONDIKE STAMPEDE, WHICH
WAS THE GREATEST GOLD RUSH.

Stewart says RIGHT.
AND IT IS A MONUMENT
IN A VERY SPECIAL WAY.
PARKS CANADA HAS
DONE A LOT WITH IT.

The student says AND IT'S FULL OF OLD MINING
CAMPS, ABANDONED VILLAGES,
AND GHOST TOWNS.

Stewart says GHOST TOWNS, YES.
AND MINING CAMPS AND SO ON.
THAT'S EXCELLENT.

The student says DIAMOND TOOTH GERTIE'S WAS
THE FIRST MODERN LICENSED
GAMBLING CASINO IN CANADA.

Stewart says THAT'S RIGHT.
THANK YOU.

The student says PADDLE WHEEL MUSEUM AND
THE PALACE GRAND THEATRE.

Stewart says AH, THE PALACE
GRAND THEATRE.
YES.
ACTUALLY, I CAN TELL
A STORY ABOUT THAT.
THE PALACE GRAND THEATRE.
I SAW A WORLD DEBUT
OF A MOVIE THERE.
AND WHAT WAS THE
OTHER ONE YOU SAID?

The student repeats PADDLE WHEEL MUSEUM.

Stewart says THE OLD PADDLE BOATS USED TO GO
UP AND DOWN THE YUKON RIVER.

The student says AND YOU CAN PAN FOR GOLD.

Stewart says YES, YOU CAN.
EXCELLENT.
YOU CAN PAN FOR GOLD.
THEY'LL ACTUALLY LET YOU KEEP
THE GOLD IF YOU GET ANY.

Another student says HELLO?

Lorraine says HI.

Stewart asks WHAT HAVE YOU GOT?

The student says I HAVE THE WEATHER FORECAST.

Lorraine says GREAT.

Stewart says EXCELLENT.
WE LIKE TO KNOW THE WEATHER.

The student says OKAY, IT'S SUNNY
WITH CLOUDY PERIODS.
THE UV IS 4.3 OR MODERATE.
THE HIGH IS NEAR 18, AND THE
PROBABILITY OF PRECIPITATION
IS 20 PERCENT.

Stewart asks 20 PERCENT?

The student says YES.

Stewart says YOU KNOW SOMETHING, I WOULDN'T
MIND BEING UP THERE TODAY.

Lorraine says YEAH.
IT'LL BE BEAUTIFUL WEATHER.

Stewart says FACT IS, ABOUT THE
SAME AS TODAY HERE.

The student says OKAY, THAT'S ALL I GOT.

Stewart says SUPER.

The student says OKAY, BYE-BYE.

Stewart asks HAVE WE GOT ANYBODY ELSE?

Lorraine says THAT WAS EXCELLENT.

Stewart says BOY, JACK MINER HAS JUST DONE
A GREAT JOB TO SAY THE LEAST.

Lorraine says YES.
THANK YOU VERY MUCH.
EXCELLENT.
AND I DO BELIEVE
WE HAVE A VIDEO.

Stewart says WE DO HAVE A VIDEO.
AND MAYBE THE PALACE
GRAND IS IN THERE.
I'M NOT SURE.

Lorraine says THAT'S RIGHT.
ENJOY.

(music plays)
A video starts playing.

It shows an aerial view of a small city by the river.

Several clips show western style buildings.

Stewart and Lorraine reappear in the studio. Lorraine is wearing a white blouse with flowers, and Stewart is wearing a white T-shirt with a picture of Albert Einstein in it.

Lorraine says HELLO, AND WELCOME
TO MATH MYSTERY.
I'M LORRAINE GOWER.

Stewart says AND YOU HAVE A
BEAUTIFUL BEAUTY MARK.

Lorraine says INDEED.

She takes off the fake beauty mark from her cheek.

Stewart says AND I'M STEWART,
AND I'M BACK.

Lorraine says I STOLE IT FROM
Mrs. G., YOU KNOW?
I WANTED TO BE A
LITTLE BIT LIKE HER.

Stewart says THERE YOU ARE.

Lorraine says IN A WAY, WE CERTAINLY
HAVE SOME MATH TO SHOW
THE STUDENTS TODAY.

Stewart says I THINK THE FIRST THING WE'VE
GOT TO DO IS GO BACK TO THAT
PROBLEM THAT I LEFT WITH
EVERYBODY ON THURSDAY.

Lorraine says GOOD IDEA.

Stewart continues REMEMBER IT WAS AT A
CHESSBOARD OR A CHECKERBOARD?
I'M GOING TO MOVE
THIS OUT OF THE WAY.
TRY TO GET THIS
INTO THE RIGHT SPOT.
ZOOM BACK A LITTLE BIT.

He shows a chessboard with domino pieces scattered on it.

Lorraine says YES.
PERFECT.

Stewart says THAT'S PRETTY GOOD.
THAT'S REALLY GOOD.
NOW REMEMBER HOW THIS PROBLEM
KIND OF WENT IS THAT YOU HAD
TWO CORNERS, THERE'S ONE UP
THERE, AND ONE DOWN HERE IN
THE BOTTOM, AND THESE TWO
CORNERS WERE ELIMINATED
FROM THE CHECKERBOARD.
AND THEN YOU HAD DOMINOS, AND
YOU PUT ON HERE IN SOME WAY,
LIKE FOR INSTANCE THIS WAY,
AND THE IDEA WAS TO COVER ALL
THE SQUARES ON
THE CHECKERBOARD.
THE DOMINO COVERS TWO OF
THEM AT A TIME, SO NOTHING
OVERLAPS, AND NOTHING
STICKS OUT THE EDGE.
SO THE BIG QUESTION
HERE ACTUALLY IS
IS THERE A SOLUTION?
NOW I THINK IF I'M NOT MISTAKEN,
WE HAVE AN AREL QUESTION.

Lorraine says THAT'S RIGHT.
AND WE CERTAINLY
DO HAVE A QUESTION.
AND HERE IT IS.
YOU'LL REQUIRE YOUR PHONES.
IT SAYS

A white slate titled “Question No. 2” appears. It reads “Is there a solution to the Dominoes on a Checkerboard problem?,” and it shows two options “1. Yes” and “2. No.”
A vertical bar with a percentage starts filling.

Stewart says WE'RE GETTING
ANSWERS IN QUICKLY.
74 PERCENT ALREADY.
WE'RE DOING REALLY WELL.
WE LOVE 80 PERCENT.
THERE'S 80.
WHY DON'T WE JUST TAKE A LOOK
AT OUR RESULT UP TO THIS POINT?
MOST PEOPLE THINK THAT
THERE IS A SOLUTION.
YOU KNOW, I WOULD REALLY LIKE
TO ASK SOMEBODY IN THAT GROUP
TO PHONE IN, AND LET US KNOW
HOW I WOULD DO THE SOLUTION.

Lorraine says WELL, I'VE LOCKED IN THE
STUDENTS THAT HAVE ANSWERED
YES, AND HERE WE GO.
WE'LL START OFF WITH
SOMEONE FROM FLAMBOROUGH.
AND SEE WHY YOU CHOSE YES.
IT'S ALEXIS OR ELISA.

Stewart says PRETTY SOON WE'RE
GOING TO BE READY THERE.
IT'LL BE INTERESTING, I DON'T
KNOW IF I CAN DO THIS QUICKLY
ENOUGH, BUT I'LL
GIVE IT A TRY.

Lorraine says OKAY.
HELLO.

Elisa says HI.

Stewart says HI.
YOU SAID YES TO THE ANSWER
TO THE QUESTION, RIGHT?

Elisa says YES.

Stewart asks CAN YOU TELL ME
HOW I WOULD DO IT?

Elisa says I JUST GUESSED.

Stewart says YOU GUESSED.

Elisa says YES.

Stewart says YOU THINK THERE'S A SOLUTION.
WHAT WOULD YOU TRY TO DO?
HOW WOULD YOU ARRANGE THESE?
WOULD YOU START THE
WAY I DID UP THERE?

Elisa says JUST ONE MINUTE.

Lorraine says OKAY.

Stewart asks YOU STILL WITH US?

Elisa says HELLO?

Stewart says HELLO.
WOULD YOU START THE WAY I DID,
OR WOULD YOU TRY SOME OTHER WAY?

Elisa says I'M REALLY NOT SURE.

Stewart says OKAY, FAIR ENOUGH.

Elisa says I'D START AROUND THE OUTSIDE.

Stewart says YOU'D START AROUND THE
OUTSIDE, LIKE GOING LIKE THIS?

Stewart puts the domino pieces so that they occupy two squares each in a spiral pattern.

Elisa says YEAH.

Stewart says THAT'S NOT A BAD IDEA.
AND SO ON.
NOW, I COULD KEEP GOING.
YOU WANT ME TO DO THAT, SEE
IF I CAN DO IT REALLY FAST.

Elisa says OKAY.

Lorraine says OKAY, I CAN HELP YOU.

Stewart says I'M GOING TO DO THAT.
REMEMBER, WE'VE GOT
KIND OF A PATTERN HERE.
I'M GOING TO BE
ACROSS IN HERE.
THAT'S GOOD.
OH, LET'S SEE.
BOY, A LOT OF -- LET'S SEE.
PUT THAT ONE THERE, PUT THAT
ONE THERE, THAT ONE THERE, AND
THAT ONE THERE, AND THAT ONE
THERE, AND THAT ONE, AND THAT
ONE, AND THAT
ONE, AND THAT ONE.
AND YOU KNOW SOMETHING, I
MISSED THIS ONE WAY DOWN HERE
AT THE BOTTOM.
YOU KNOW, I'M JUST GOING TO MAKE
A LITTLE REARRANGEMENT THERE.
UH-OH, I'M IN TROUBLE.
I CAN'T DO THAT BECAUSE
IT'S ON A DIAGONAL.

Lorraine says WE'VE GOT ONE LEFT.

Stewart says THAT DOESN'T SEEM
TO HAVE WORKED.
PERHAPS WE COULD
TRY SOMEBODY ELSE.

Lorraine says THANKS.

Elisa says BYE.

Stewart says THANK YOU VERY MUCH.

Lorraine says OKAY, WE DO HAVE HERE
SOMEONE FROM COLLEGE.
NADEPA.

Nadepa says HELLO?

Lorraine says HI, AND WHAT DID YOU
COME UP WITH HERE?

Stewart asks IS THERE A SOLUTION?

Lorraine says YOU ANSWERED YES,
AND WHY IS THAT?
HOW DID YOU COME UP
WITH THAT ANSWER?

Nadepa says I GUESSED.

Lorraine says YOU GUESSED.

Nadepa says I THINK IT'S POSSIBLE.

Stewart says YOU THINK IT'S POSSIBLE,
BUT YOU HAVEN'T GOT AN
ILLUSTRATION OF IT.
YOU HAVEN'T ACTUALLY DONE IT.

Nadepa asks HOW COME THERE'S ONE COVERED?
OR LIKE TWO?

Stewart says THAT'S THE ESSENCE
OF THE PROBLEM.
BECAUSE THESE TWO ARE TAKEN
OUT OF THE CHESSBOARD.
SO THE IDEA IS TO ASK THE
QUESTION WHETHER YOU CAN COVER
THE REST OF THE CHECKERBOARD
USING DOMINOS THAT COVER
TWO AT A TIME.

Nadepa says HOW ABOUT GO
DOWN FOR EACH ONE?

Stewart says WE COULD DO THAT.

Stewart starts rearranging the domino pieces.

Lorraine says AND MAYBE, TO SIMPLIFY
THINGS... THANKS, NADEPA.

Stewart says MAYBE WE SHOULD ASK SOMEBODY
WHO SAID NO, AND WHY THEY
SAID NO.

Lorraine says OKAY.

Stewart says WHILE I'M TRYING TO DO IT
THIS OTHER WAY, WHERE WE'RE
GOING DOWN FOR
EACH ONE OF THEM.

Lorraine says OKAY, WE'RE CALLING JENNIFER
OR CHANTAL FROM FLAMBOROUGH
WHO ANSWERED NO.
AND WE'LL SEE WHY.
WHILE YOU ARE GOING DOWNWARDS,
LIKE NADEPA SUGGESTED.

Stewart says I SEE A PROBLEM HERE.
I'VE GONE DOWNWARDS,
AND I GET STUCK.

Lorraine says HELLO.
AND YOU ARE?

Chantal says CHANTAL.

Lorraine asks WHY DID YOU ANSWER NO?

Chantal says I GUESSED.

Lorraine says SO YOU GUESSED AS WELL.

Stewart says SO WE DON'T REALLY HAVE A
SOLUTION TO THIS AS YET.
WELL, THERE -- I THINK I'VE
GOT TO TELL YOU, CAN YOU PUT
THE GRAPH BACK UP THERE AGAIN?

Lorraine says CERTAINLY.

A slate shows the question, and a bar graph. It shows the number 32 under a green bar and the number 12 under a purple bar.

Stewart says IF I WERE A GUESSING PERSON,
AS IT TURNS OUT, THE PEOPLE
ON THE RIGHT HAND, MY RIGHT
HAND SIDE, THE PEOPLE THAT
SAID NO ARE CORRECT.
IT CANNOT BE DONE.
BUT WITH ANYTHING LIKE THIS.

Lorraine says IT WAS A GOOD GUESS,
JENNIFER, I BELIEVE.

Stewart continues IT'S GOT TO BE
MORE THAN A GUESS.
YOU'VE GOT TO SORT
OF HAVE A PROOF.
AND SO MUCH IS INVOLVED WITH
PROOF WHEN YOU DO MATHEMATICS.
AS IT TURNS OUT, THERE IS
ACTUALLY A VERY SIMPLE
EXPLANATION AS TO WHY
THIS CANNOT BE SOLVED.
AND HERE'S HOW IT GOES.
FIRST OF ALL, I'M GOING
TO TAKE ALL THESE OFF.
MAKE A BIG NOISE.
AS YOU CAN SEE, WHEN I
PUT ONE OF THESE ON HERE,
WHAT HAPPENS?
WHAT DO I COVER?
SO MAYBE WE SHOULD GET
SOMEBODY ON THE LINE AND MAYBE
TALK A LITTLE BIT AS
WE ARE DOING THIS.
IF I PUT ANY ONE DOMINO ON
HERE, WHAT CAN YOU SAY HAPPENS
EACH TIME I PUT ONE ON.
DOESN'T MATTER WHERE I DO IT.
AND REMEMBER, YOU
CAN'T GO DIAGONALLY.
SO HAVE WE GOT
DAVID ON THE LINE?

Lorraine says HELLO?

David says HI.

Stewart says WHEN I PUT A DOMINO ON THE
BOARD, CAN YOU DESCRIBE WHAT
IS HAPPENING IN TERMS
OF THE CHECKERBOARD?

David says ONE'S COVERING WHITE,
AND ONE'S COVERING BLACK.

Stewart says EXACTLY.
THAT'S A GOOD OBSERVATION.
NEXT QUESTION, AND I'M GOING
TO KEEP DAVID THERE BECAUSE
YOU STARTED REALLY WELL.
HOW MANY WHITE SPOTS RIGHT
NOW, NOT COUNTING, REMEMBER,
THESE ARE NOT WHITE.
BY DEFINITION, THESE
ARE BLOTTED OUT.
HOW MANY WHITE SPOTS ARE
LEFT ON THE BOARD NOW?

David says 38.

Stewart asks HOW MANY TOTAL SPOTS ON AN
EIGHT BY EIGHT CHECKERBOARD?

David says 31.

Stewart says OKAY, NOW YOU'RE SAYING 31.
BUT LET'S CHECK THAT OUT.
IN FACT, THE WHITE SPOTS, I
COVERED A BLACK ONE DOWN HERE,
AND A BLACK ONE DOWN HERE.
SO I WOULD SAY THERE
ARE 32 OF THESE, RIGHT?
ONE, TWO, THREE, FOUR,
FIVE, SIX, AND SO ON.
SO DO YOU AGREE THERE
ARE 32 WHITE SPOTS?

David says YES, AND 30 BLACK SPOTS.

Stewart says EXACTLY.

Stewart says NOW, CAN SOMEBODY PROVIDE THE
ARGUMENT WHY THIS CAN'T BE
SOLVED IF THERE ARE 30
BLACK ONES THERE, AND 32 WHITE
ONES, GIVEN THE OBSERVATION
YOU GAVE US ALREADY, DAVID,
THAT WHEN I PUT ONE OF THESE
ON I COVER ONE OF THESE.
SO WHAT'S THE ARGUMENT?

David says YOU CAN'T HAVE ONE
COVERING TWO WHITE SPOTS.

Stewart says EXACTLY.
AND THAT'S GOING TO
HAPPEN INEVITABLY.
SO WHAT HAPPENS HERE, FOR THE
FIRST 30 TILES, YOU COVER A
BLACK AND WHITE ONE EACH TIME,
HOWEVER YOU'RE ALWAYS LEFT
WITH TWO WHITE ONES.
AND YOU CAN'T COVER THEM
BECAUSE THEY ARE DIAGONAL.
VERY GOOD.

Lorraine says YES, GOOD FOR YOU, DAVID.
THANKS.
AND WE'RE GOING TO BE STARTING
WITH YOUR EXERCISE HERE.
WITH EXERCISE ONE.

She shows an exercise in a piece of paper. It reads “The North West Mounted Police set up a post at the apex of the Chilkoot Path. They decreed that no person could enter the Yukon Territory without the following provisions: 180 kg of flour, 23 kg of oatmeal, 46 kg of beans, 46 kg of granulated sugar, 92 kg of bacon, 16 kg of yeast cakes, 0.5 kg of pepper, 0.12 kg of ginger, 11kg of evaporated peaches, 11 kg of fish, 23 kg of evaporated onions, 2 kg of tea, 11 kg of coffee, 60 boxes of matches, 25 cans of butter, 23 kg of cornmeal, 16 kg of rice, 18 kg of candles, 4 kg of baking powder, 1 kg of soda, 7 kg of salt, 0.25 kg of mustard, 11 kg of evaporated apples, 11 kg of evaporated apricots, 4 kg of pitted plums, 23 kg of evaporated potatoes, 4 dozens tins of condensed milk, 5 bars of laundry soap, 7kg of vegetables soup. A. Including the 1000 dozen eggs, the other food provision from the list, clothing, pots and pans, and a bedroll, calculate the total mass that the enterprising merchant had to transport into the Yukon.”

Lorraine says SO IF YOU CAN HAVE YOUR COPY
IN FRONT OF YOU, WITH EXERCISE
ONE, NUMBER ONE, AND WE'RE
GOING TO CONCENTRATE ON THE
SECTION HERE THAT HAS A LOT OF
DIFFERENT INGREDIENTS AND SO ON.
AND STEWART.

Stewart is standing behind a table with several products on it.

Stewart says I KIND OF MOVED ON OVER HERE
TO THE SIDE TABLE JUST TO
ACTUALLY SUGGEST, THIS IS A
LITTLE PROJECT THAT I THINK
YOU HAVE TO TAKE ON
AS AN ENTIRE CLASS.
SIMPLY BECAUSE IF YOU WERE TO
TRY TO GO THROUGH THAT ENTIRE
LIST AND WORK OUT THE VOLUME
OF EVERY SINGLE ITEM, YOU
WOULD NOT -- IT WOULD TAKE
YOU A LONG, LONG TIME,
AND PERHAPS YOU DON'T
HAVE ALL THE ITEMS.
SO FOR ANY GIVEN SCHOOL,
PERHAPS EACH STUDENT IN THE
CLASS COULD TAKE ONE OR TWO
ITEMS, AND GO HOME, DO A
LITTLE BIT OF WORK, PERHAPS
TONIGHT OR TOMORROW AFTER SCHOOL
OR WHATEVER, AND
FIND SOME VOLUMES.
WHAT I'M GOING TO DO, I'M
GOING TO TAKE THESE KIND OF
ONE AT A TIME.
CAN I GO BACK TO THE GRAPHICS
CAMERA THERE FOR A MOMENT.

Lorraine says CERTAINLY CAN.

Stewart says THE VERY TOP ONE UP THERE IN
THE CORNER IS 180 KILOGRAMS
OF FLOUR.
THIS OVER HERE, AND WE CAN
COME BACK TO ME AGAIN,
THIS IS A 2.5 KILOGRAM BAG.
NOW, YOU CAN FIND THE VOLUME
OF THIS RELATIVELY EASILY
BECAUSE IT IS A
RECTANGULAR PRISM.
REMEMBER, WHEN THEY PACKED
THESE THINGS WHEN THEY WERE
GOING INTO THE KLONDIKE, THEY
DIDN'T WORRY ABOUT PACKAGING
SO MUCH, SO YOU DON'T
HAVE TO WORRY AT THAT.
BUT ONE OF THE THINGS I WANT
TO TELL YOU IS A LITTLE BIT OF
A STORY, AND THE REASON
WHY THE QUESTION.
AND THEN I'LL DESCRIBE ONE
OR TWO OF THESE OBJECTS.
IT WAS REQUIRED BY THE
NORTHWEST MOUNTED POLICE THAT
WHEN THE PROSPECTORS CAME INTO
THE YUKON, THEY HAD TO BRING
THAT ENTIRE LIST
OF PROVISIONS.
EVERY SINGLE ONE OF THEM.
WELL, THE PROBLEM IS THEY HAD
TO CARRY ALL THAT STUFF UP
THROUGH A MOUNTAIN PASS
CALLED THE CHILKOOT PASS.
THAT WAS A LOT OF
WORK ALL BY ITSELF.
IT MIGHT HAVE TAKEN A
PROSPECTOR 20 TRIPS UP THE
MOUNTAIN TO GO UP, TAKE SOME
STUFF UP, GO BACK DOWN, GET
SOME MORE, AND SO ON.
BUT WHEN THEY GOT TO THE TOP,
THEY WOULD TRAVEL A LITTLE
FURTHER TO A LAKE
CALLED LAKE BENNETT.
AND ON LAKE BENNETT, THEY
WOULD HAVE TO EITHER BUILD A
BOAT OR A RAFT, OR BUY A BOAT
OR A RAFT, WHICH WASN'T TOO
EASY AT THE TIME,
AND PACK IT ALL IN.
SO ONE OF THE THINGS I WAS
CURIOUS ABOUT IS HOW BIG DID
THE RAFT OR BOAT HAVE
TO BE TO CARRY ALL THIS?
SO I THINK WE'VE TALKED A BIT
ABOUT FLOUR, AND TO BE QUITE
HONEST, SUGAR IS PRETTY
MUCH THE SAME PROBLEM.
SUGAR COMES IN 2 KILOGRAM BAG.
IT MAY NOT TAKE UP THE SAME
VOLUME PER KILOGRAM, BUT AGAIN
SAME KIND OF PROBLEM.
AGAIN, WITH RICE, YOU'VE
GOT THE SAME PROBLEM.
NOW REMEMBER, THEY WOULDN'T
HAVE THE PACKAGING LIKE THIS.
THERE'S A FAIR BIT
OF AIR IN THERE.
YOU MAY WANT TO TRY TO
TAKE THAT INTO ACCOUNT.
THIS IS A 350 GRAM
PACKAGE OF RICE.
HOW MUCH RICE DID
THEY NEED BY THE WAY?

Lorraine says WELL, LET'S LOOK AT
THE INFORMATION HERE.
AND RICE HERE IS 16 KILOGRAMS.

Stewart says SO 16 KILOGRAMS OF RICE.
SO, IN FACT, YOU'D NEED
ABOUT 50 PACKAGES OF THAT.
YOU DON'T WANT THE PACKAGING,
YOU DON'T WANT THE AIR.
BEANS.
NOW IF THEY CAME IN THESE
LITTLE WEE TINY CANS,
THEY'D HAVE TO STACK THEM
TOGETHER PRETTY WELL.
BUT AGAIN, BEANS, YOU CAN
WORK OUT THE VOLUME OF THAT.
I THINK WE USED SOME FORMULAS
BACK WHEN WE DID THE NASA THING.

Lorraine says WE CERTAINLY DID.

Stewart says HEY, LET'S HAVE
A LITTLE FUN HERE.
MAYBE WE CAN ASK THE STUDENTS.
WHAT'S THE FORMULA FOR
THE VOLUME OF A CYLINDER?

Lorraine says OKAY, CALL US BY
PRESSING POUND NINE.
SHARE WITH US THE FORMULA.
HERE WE HAVE SEVERAL STUDENTS.
WE ARE GOING TO CONNECT
WITH JACK MINER.

Stewart says OH, GREAT.

Lorraine says ALEX FROM JACK MINER.

Stewart says HI, ALEX.
ARE YOU THERE?

Alex says YEAH.

Stewart says OH, THERE YOU ARE.
REMEMBER THE FORMULA FOR
THE VOLUME OF A CYLINDER?

Alex says YEAH.

Stewart asks CAN YOU TELL IT TO US?

Alex says PI R SQUARED H.

Stewart says EXCELLENT.
SO THAT'S THE FORMULA YOU
WOULD USE TO BASICALLY FIGURE
OUT THE VOLUME OF A CAN.
AND OF COURSE, HOW MANY
KILOGRAMS OF BEANS DID WE NEED?

Lorraine says WELL...
HOW MANY DO YOU
HAVE IN FRONT OF YOU?
AND THAT IS ALEX.
DO YOU HAVE YOUR
COPY IN FRONT OF YOU?

Alex says YEAH, 46.

Lorraine says YEAH, VERY GOOD.
46 KILOGRAMS.

Stewart says NOW ONE OF THE LITTLE
PROBLEMS WITH THIS IS THAT
THE MEASUREMENT ON THE
CAN IS NOT ABOUT MASS,
IT'S ABOUT VOLUME.
IT'S 227 MILLILITRES.
YOU MAY ACTUALLY HAVE TO TAKE
THIS CAN AND GET THE MASS OF
IT TO FIND OUT HOW MANY CANS
YOU WOULD ACTUALLY NEED
FOR 46 KILOGRAMS.
THE SAME PROBLEM YOU RUN INTO
WITH, I'VE GOT TUNA IN THIS
CASE, THEY WOULD HAVE
SAID FISH BACK THEN.
IT WOULD HAVE BEEN AWFULLY
NICE TO HAVE TUNA, BUT I'M NOT
SURE EXACTLY WHAT KIND OF FISH
THEY WOULD HAVE TAKEN IN.

Lorraine says THANKS, ALEX.

Stewart continues NOW, WE'VE GOT A COUPLE OF
OTHER THINGS THAT ARE KIND OF
STRANGE IN TERMS OF THE LIST.
ONE OF THE THINGS THAT IS
ON THERE ARE BARS OF SOAP.
AND I PICKED IVORY BECAUSE,
WELL, ACTUALLY I'M NOT GOING
TO BE TOO SUCCESSFUL AT TAKING
THESE TWO BARS APART, BUT WE
HAVE TWO BARS OF SOAP HERE.
AND THEY ARE IN NICE
RECTANGULAR PRISM BOXES.
AND THIS MIGHT BE SIMILAR TO
THE KIND OF SOAP, OR AT LEAST
THE SIZE OF BAR
THEY WOULD TAKE.
HOW MANY BARS OF
SOAP DID THEY NEED?
A LOT.

Lorraine says SOAP...
LAUNDRY SOAP WAS FIVE BARS.

Stewart says THAT'S LAUNDRY SOAP.
IT MIGHT HAVE EVEN
BEEN BIGGER THAN THAT.
BUT WE'LL USE THAT
FOR OUR SIMULATION.
NOW, MAYBE WE CAN ASK STUDENTS
WHY THEY NEEDED THESE THINGS?
THIS IS A CANDLE.
HOW MANY CANDLES
WERE REQUIRED?

Lorraine says WE HAVE SOMEONE
FROM USBORNE CENTRAL.
HELLO.

A student says 18 KILOGRAMS.

Stewart says 18 KILOGRAMS OF CANDLES.
WHY WOULD THEY NEED
SO MANY CANDLES?

The student says BECAUSE THERE PROBABLY
WAS NO ELECTRICITY.

Stewart says YOU'RE ABSOLUTELY RIGHT.
THERE WAS NO ELECTRICITY.
AND I THINK YOU'LL NOTICE
LATER IN THAT LIST THEY ASKED
FOR SOMETHING ELSE THAT I
THINK THEY WOULD ALSO NEED
IF THEY HAD CANDLES.
I THINK THEY NEED MATCHES,
AND LOTS OF THEM.

Lorraine says YES, 60 BOXES.

Stewart continues THEY DIDN'T HAVE LIGHTERS
BACK THEN EITHER.
SO AGAIN, WHAT THEY WOULD HAVE
BEEN REQUIRED TO DO IS BRING
WOODEN MATCHES AND
ALL KINDS OF CANDLES.
THERE WAS NO OTHER SOURCE OF
LIGHT, OTHER THAN PERHAPS
WHALE OIL OR SOMETHING
ALONG THAT LINE.

Lorraine says OKAY, THANKS, AMANDA.

Stewart says THE LAST THING I WANT TO
COMMENT IN TERMS OF THE KINDS
OF THINGS YOU FIND ON THAT
LIST ARE THINGS LIKE, WELL,
WE'VE GOT DRIED FRUIT.
AND THIS WOULD HAVE BEEN
A PRETTY COMMON THING.
THEY COULDN'T HAVE BROUGHT
FRESH FRUIT INTO THE YUKON,
THE VOLUME WOULD HAVE
BEEN JUST TOO GREAT.
THEY WOULD HAVE TAKEN
GOOD FRUIT AND DRIED IT.
AND EVEN TO THIS DAY,
IT'S QUITE TASTY STUFF.
SO YOU MIGHT NEED TO GO OUT
AND GET A PACKAGE OF SOMETHING
LIKE THIS, AND FIND OUT,
WELL, THIS IS 170 GRAMS.
AND IN SOME WAY, PACK IT INTO
SOMETHING ELSE SO YOU CAN GET
A VOLUME ESTIMATE
FOR THE DRIED GOODS.
APRICOTS, APPLES, ALL THOSE
THINGS WOULD BE MORE OR LESS
THE SAME.
SO I MEAN, I THINK PERHAPS WE
SHOULD OPEN THE FLOOR UP TO
SOME QUESTIONS FROM THE
STUDENTS ABOUT MAYBE SOME OF
THESE THINGS THAT THEY
MIGHT BE LOOKING FOR.
IF NOT, WE CAN GO ON TO
QUESTION NUMBER TWO.

Lorraine says YES, AND AS FAR AS I CAN
SEE, THERE ARE NO QUESTIONS.
SO WE WILL CONTINUE WITH
EXERCISE ONE QUESTION NUMBER
TWO, WHICH LOOKS LIKE THIS.
IT SAYS POPULATION BOOM.
WE'RE GOING TO BE GOING OVER
THIS TOMORROW IN MORE DETAIL.
WHAT THEY ARE ASKING YOU IS
ON THE AXIS BELOW, GRAPH THE
POPULATION DENSITY OF QUEBEC,
MANITOBA, BRITISH COLUMBIA,
AND YUKON TERRITORY.
WELL, TOMORROW, WE'RE GOING
TO TALK ABOUT FOUR OTHER
PROVINCES AND GIVE
YOU SOME EXAMPLES.
THEREFORE, YOU'RE GOING TO
REQUIRE GRAPH PAPER TOMORROW.
IF YOU DON'T HAVE ANY GRAPH
PAPER, AT LEAST WHITE PAPER
AND YOU CAN BRING A RULER.
THIS WAY WE CAN DO SOME
GRAPHING, AND COME UP WITH
GREAT IDEAS, AS FAR AS THE
INFORMATION THAT YOU SEE IN
FRONT OF YOU.
AND YOU'LL NOTICE, AS WELL, IN
EXERCISE ONE, QUESTION TWO,
IS A CONTINUATION, POPULATION
BOOM, WITH SOME QUESTIONS,
AND WE'LL GO OVER THAT
QUICKLY, AS WELL.
AND FOR QUESTION NUMBER THREE,
I UNDERSTAND, STEWART,
WE HAVE AN EXPERIMENT
FOR THE STUDENTS TO DO.

Stewart is holding ten white marbles on his right hand, and ten transparent marbles on his left hand.

Stewart says AGAIN, I WOULD PROPOSE, I'M
GOING TO HOLD THESE MARBLES
OUT HERE RIGHT NOW.
THIS IS ABOUT GAMBLING.
AND YOU KNOW, PART OF THE
YUKON WAS A LITTLE BIT
ABOUT THE WHOLE -- THERE
WAS A CULTURE OF GAMBLING.
MAYBE ONE OF THE REASONS
DIAMOND TOOTH GERTIE'S WAS THE
FIRST CASINO IN CANADA,
THE FIRST LICENSED ONE.
NOW, LET'S SAY WE HAD A
LITTLE BIT OF A PROBLEM.
THAT IS TO SAY, THE RCMP HAS
CAUGHT YOU DOING SOMETHING
THAT YOU SHOULDN'T
HAVE BEEN DOING.
MAYBE PERHAPS USING SOMEBODY
ELSE'S FIREWOOD WHEN YOU
SHOULDN'T HAVE BEEN USING IT.
AND THEY'VE DECIDED
TO PUNISH YOU.
YOU'VE BEEN FOUND GUILTY.
HOWEVER, THEY ARE GOING TO LET
YOU OFF THE HOOK BECAUSE IT'S
A BIT OF A GAMBLING
CULTURE UP THERE.
THAT IS TO SAY, WE HAVE
TEN SOLID MARBLES,
AND TEN CLEAR ONES.
AND THEY ARE GOING TO
BE PUT INTO TWO VESSELS.
THE GOOD NEWS IS YOU GET TO
SPLIT THEM WHATEVER WAY
YOU WANT.
NOW, IF YOU DRAW OUT A CLEAR
ONE, THEN YOU WILL BE SET FREE.
THERE WILL BE NO PUNISHMENT.
HOWEVER, IF YOU DRAW OUT A
SOLID ONE, YOU'LL BE FORCED TO
CUT FIREWOOD ON THE WOOD LOT
FOR THE WHOLE COLD WINTER.
AND I'LL TELL YOU, IT IS
REALLY COLD IN DAWSON CITY
IN THE WINTER.
AND, TO BE QUITE HONEST, IT IS
A HISTORICAL FACT, THAT WAS
THE MOST FEARED OF ALL
PUNISHMENTS TO WORK THE RCMP
WOOD LOT.
BUT THEY'VE GIVEN YOU A BIT
OF A CHANCE TO GET AWAY WITH
SOMETHING HERE.
SO HERE'S HOW IT
KIND OF WORKS.
I'LL GET THESE MARBLES
KIND OF MUSHED UP HERE.

Stewart shows two small white boxes on the table.

He says I'VE GOT TWO CONTAINERS.
THEY HAVE TO BE IDENTICAL.
AND YOU CAN SEE THEM
IN THE OVERHEAD CAMERA.
GOT TO GET USED TO
REVERSE ORIENTATION HERE.
GET IT OVER THERE
A LITTLE BIT.
AND WHAT I GET TO DO IS I
CAN SPLIT THESE MARBLES UP
ANY WAY I WANT TO.
SO I'M GOING TO PUT A FEW OF
THE CLEAR ONES IN HERE, AND A
FEW OF THEM IN THERE, WITH A
FEW SOLID ONES IN THERE, AND A
COUPLE OF SOLID OVER HERE.
WHAT WOULD HAPPEN, ONCE YOU
DID THAT, THE RCMP WOULD TAKE
THESE AND MIX THEM UP.

He takes the boxes and moves them around the table.

Stewart continues SO YOU DIDN'T KNOW
WHICH ONE IS WHICH.
SO I GOT THEM
ALL MIXED UP NOW.
WE DON'T KNOW
WHICH ONE IS WHICH.
AT LEAST LORRAINE DOESN'T.
LET'S SAY SHE'S THE ONE
THAT'S TO BE PUNISHMENT.
AND I'M GOING TO ASK LORRAINE,
WHICH ONE OF THESE TWO
VESSELS SHE WANTS TO PICK.
THE ONE ON MY RIGHT,
OR THE ONE ON MY LEFT?

Lorraine says WELL, I'M GOING TO
SAY, EENIE MEANIE...
OKAY, ON YOUR RIGHT.

Stewart says ON MY RIGHT.
I'M GOING TO HAVE TO
SIMULATE THE DRAW FOR HER.
I'M NOT LOOKING.
I'M GOING IN THERE.
REMEMBER, IF IT IS
CLEAR, SHE IS FREE.
IF IT IS SOLID, SHE
WORKS THE WOOD LOT.

Stewart takes a white marble out of the box.

He says OH, THAT'S TOO BAD.

Lorraine says I BETTER START
EXERCISING NOW, I GUESS.

Stewart says IT'S GOING TO BE A TOUGH
WINTER, I CAN TELL YOU.
NOW WHAT I'M PROPOSING THE
STUDENTS DO IS EACH ONE OF YOU
TAKE A DIFFERENT SCENARIO TO
DO WITH HOW YOU SPLIT THE
MARBLES, AND MAYBE DO THE
EXPERIMENT TEN TIMES.
THEN BRING ALL THAT
INFORMATION BACK TO THE CLASS
AS A WHOLE, ONCE AGAIN
AND ACCUMULATE IT.
AND MAKE SOME DECISIONS ABOUT
HOW WOULD BE THE BEST WAY TO
SPLIT THE MARBLES SO YOU HAVE
THE BIGGEST CHANCE OF DRAWING
A CLEAR MARBLE.
IT IS NOT ABSOLUTELY OBVIOUS.
IT'S NOT 50/50.
NECESSARILY.
SO YOU HAVE TO DO THE
EXPERIMENT TO FIND OUT THAT
THERE'S A DIFFERENCE.
THEN TRY TO WORK IT OUT SO
YOU CAN UNDERSTAND WHY THE
DIFFERENCE, WHICH IS THE
IMPORTANT PART OF IT.
FACT IS, I THINK ONE OF THE
THINGS THAT YOU COULD USE
THAT'S PART OF THE CURRICULUM
IN GRADE SEVEN AND EIGHT IS A
TREE DIAGRAM.
SO YOU MIGHT WANT TO
TRY THAT, AS WELL.

Lorraine says GREAT IDEA.
AND WE DO HAVE A CALL.

Stewart says GREAT.
LET'S TAKE A CALL.

Lorraine says OKAY.
AND IT'S FROM FLAMBOROUGH.
AND IT'S RYAN.
LET'S TRY THAT AGAIN.
HERE WE GO, RYAN
FROM FLAMBOROUGH.

Stewart says HELLO, RYAN.

Lorraine says HE'S NOT ON YET.
HE'LL BE CONNECTING
IN A FEW SECONDS.

Stewart says THERE'S THAT SILENCE.
THE CALM BEFORE THE STORM.
NOT QUITE.

Lorraine says THAT'S RIGHT.
HELLO, RYAN.

Ryan says HOW COME YOU PUT ALL THE
MARBLES IN TWO BOXES?
WHY DIDN'T YOU JUST PUT THEM
ALL IN ONE BOX AND THEN PICK
THEM OUT OF THERE?

Stewart says THE PROBLEM IS A
VERY SPECIAL PROBLEM.
THAT IS TO SAY, IT'S
DESIGNED TO USE TWO VESSELS.
AND THAT YOU HAVE TO PUT AT
LEAST ONE MARBLE IN EACH VESSEL.
YOU CANNOT LEAVE
ONE ENTIRELY EMPTY.
BUT BECAUSE THERE ARE TWO
VESSELS, WHAT YOU'LL FIND IS
THE PROBABILITY IS NOT
NECESSARILY 50/50,
OR ONE-HALF, ONE-HALF.
REMEMBER, I USED
TEN OF EACH COLOUR?
SO IT MIGHT SEEM ON THE FACE
OF IT THAT IT'S 50-50,
BUT IT'S NOT BECAUSE
THERE ARE TWO VESSELS.
SO REMEMBER HOW IT WORKS.
YOU, THE PRISONER, THE
PERSON THAT MIGHT BE IN REAL
TROUBLE, YOU GET TO CHOOSE
WHAT WAY YOU SPLIT THE MARBLES.
YOUR CHOICE.
THEN ONCE YOU DO THAT, THE
RCMP TAKE THE URNS AWAY,
OR WHATEVER YOU WANT TO CALL
THESE, AND MIX THEM UP SO YOU
DON'T KNOW WHICH ONE IS WHICH.
JUST LIKE I DID WITH LORRAINE.
I SAID, PICK ONE OF THEM.
SHE DOESN'T KNOW
WHICH ONE IS WHICH.
SO SHE PICKS THE ONE
ON THE RIGHT-HAND SIDE.
THEN SHE WOULD ACTUALLY PUT
HER HAND IN AND DRAW OUT A
MARBLE WITHOUT LOOKING
AND RECORD WHETHER SHE
WAS SET FREE OR NOT.
NOW, REMEMBER, IF YOU REPEAT
THE EXPERIMENT A FEW TIMES, IT
WILL IRON OUT THOSE PROBLEMS
WITH A BIT OF AN ANOMALY.

Lorraine says AND OUR STUDENTS ARE EXPERTS
AT PROBABILITY NOW, THEREFORE...

Stewart says SO THIS IS ANOTHER
INTERESTING EXPERIMENT.

Lorraine says WE'VE WORKED ON THAT ALREADY.

Stewart continues THE RESULT IS NOT EXACTLY
AS YOU MIGHT IMAGINE.

Lorraine says GREAT.
THANKS FOR YOUR CALL, RYAN.
AND IF ANY OTHER STUDENTS HAVE
ANY QUESTIONS, PLEASE FEEL
FREE TO CALL US BY
PRESSING POUND NINE.
NOW, FOR OUR EXERCISE TWO,
WHICH IS AT THE BOTTOM OF
EXERCISE NUMBER ONE, QUESTION
THREE, THE ONE WE JUST
TALKED ABOUT.
THE QUESTION IN EXERCISE TWO,
SAYS THE NUMBER OF ROWS AND
THE NUMBER OF COLUMNS EACH
EQUAL THE NUMBER OF DAYS
IN A MONTH.
AND SEE THERE,
JEWELS IT SAYS.
WHO CAN CALL?

Stewart says ASSUMPTIONS ARE MADE THERE.
WHAT ARE THE ASSUMPTIONS
ABOUT DAYS IN A MONTH?

Lorraine says THAT'S RIGHT.
AND HOW MANY DAYS MAY WE
ENCOUNTER IN A MONTH?
HOW ABOUT IF YOU CALL US BY
PRESSING POUND NINE, AND SHARE
WITH US HOW MANY DAYS
CAN WE FIND IN A MONTH?
AND WE HAVE A FEW CALLS.

Stewart says OH, GOOD.

Lorraine says AND LET'S TRY HERE, TIM OR
TAD FROM USBORNE CENTRAL.
HELLO?

A student says HELLO?

Lorraine says HI.
HOW MANY DAYS CAN
ONE FIND IN A MONTH?

The student asks WHAT MONTH?

Lorraine says IT'S UP TO YOU.
ANY MONTH.
ANY OF THE 12 MONTHS.
OKAY, YOU DEFINITELY
CAN FIND 30.
WHAT OTHER ONES?

The student says 1 -- 31, 30.

Lorraine says OKAY, 31, 30, AND?

The student says 28 AND 29.

Lorraine says OKAY, EXCELLENT.
SO THE 28, RIGHT UP UNTIL 31.
SO WE HAVE TO KEEP THAT IN
MIND WHEN YOU ARE DOING
EXERCISE TWO.
OKAY?

Stewart says AND, REMEMBER, IT'S BOTH THE
COLUMNS AND THE ROWS RANGE
BETWEEN 28 AND 31.
SO THIS ALL OF A SUDDEN
CREATES A LITTLE BIT DIFFERENT
QUESTION BECAUSE I THINK
JEWELS IS TAKING US TO A REGION.

Lorraine says THAT'S RIGHT.

Stewart says AND MAYBE THERE'S AN IMPORTANT
PLACE INSIDE THE REGION?

Lorraine says HMM, MAYBE.
AND THAT'S WHY, I BELIEVE AT
THE BOTTOM HERE, JEWELS EVEN
SAYS, SEE YOU THERE.
JEWELS.
SO DEFINITELY IT'S A PLACE.

Stewart says IT MUST BE.
IT STRIKES ME, DON'T WE
HAVE ANOTHER AREL QUESTION?

Lorraine says WE CERTAINLY DO.
SO YOU SHOULD HAVE YOUR
PHONES HANDY FOR THIS.
IT SAYS

A slate appears on screen. It reads “Question No. 1. In 1900, which was the largest city west of Chicago and north of San Francisco. 1. Winnipeg. 2. Vancouver. 3. Edmonton. 4. None of the above.”
A vertical bar with a percentage starts filling.

Lorraine says WE HAVE 40 PERCENT
APPROXIMATELY.
MOVING UP QUICKLY.

Stewart says STILL A FEW MORE TO COME.
WE LIKE THAT 80 PERCENT.
I JUST LOVE 80 PERCENT.

Lorraine says INTERESTING RESULTS.
WE'LL SHOW IT WHEN
WE SEE 80 PERCENT.

Stewart says I DON'T EVEN SEE THE
RESULTS THIS TIME.
SO IT'LL BE A
SURPRISE TO ME.

Lorraine says THAT'S RIGHT.

Stewart says I'M LOOKING FORWARD
TO THIS, LORRAINE.

Lorraine says I THINK YOU'LL
ENJOY THE ANSWER.

Stewart says 73 PERCENT.
JUST A FEW MORE
PEOPLE SHOULD ANSWER.

Lorraine says 7 MORE PERCENT.
76.
COME ON, 80, 80.

Stewart says 78?

Lorraine says YEAH.
LOOK AT THAT.

A slate shows the question and a bar graph. The graph shows a 6 under a green bar, 9 under a purple bar, 11 under a blue bar, and 15 under a red bar.

Stewart says OH, THAT'S INTERESTING.
NOW, PERHAPS SOMEBODY FROM THE
RIGHT-HAND COLUMN, WHICH IS
NONE OF THE ABOVE, MIGHT BE
ABLE TO TELL US WHAT THEY
THINK THE CORRECT ANSWER IS?

Lorraine says ALRIGHT, LET'S SEE WHY SOME OF
YOU MAY HAVE CHOSEN FOUR HERE.
AND I'M GOING TO CALL
REBECCA FROM FLAMBOROUGH.
OR ASHLEY.
WHY YOU CHOSE NUMBER
FOUR, NONE OF THE ABOVE.

Stewart says NOT ONLY WHY, BUT
WHAT CITY IT MIGHT BE?

Lorraine says THAT'S RIGHT.
HI.
WE NOTICE HERE YOU
CHOSE NUMBER FOUR.
WE'LL SHOW YOU THE
QUESTION AGAIN.
WHY IS THAT?

A student says BECAUSE I GUESSED.

Lorraine says YOU GUESSED.

Stewart asks BUT WHAT PLACE DO YOU THINK
MIGHT BE LARGER THAN THOSE
OTHER THREE?

The student says I DON'T KNOW.

Lorraine says YOU'RE NOT SURE?
WE'LL TRY ONE MORE PERSON.
THANKS.

Stewart says LET'S TRY ONE MORE PERSON.
THANK YOU VERY MUCH.

Lorraine says AND IT'S EITHER DREW OR
DEREK FROM FLAMBOROUGH.

Derek says HELLO?

Lorraine says HELLO.
AND WE NOTICE YOU CHOSE NUMBER
FOUR FOR THE QUESTION HERE.
WHY IS THAT?

Derek says I GUESSED, TOO.

Lorraine says OKAY.
DO YOU WANT TO TAKE
A TRY AT WHERE IT IS?

Derek says VANCOUVER?

Stewart says WE HAD VANCOUVER ON THE LIST.
WHY DON'T WE TRY SOMEBODY
FROM JACK MINER IF THERE IS
SOMEBODY ON THE LIST.

Lorraine says WE HAVE SOMEONE FROM
St. JOHN BREBEUF.

Stewart says YES, WHY NOT.

Lorraine says AND WE'LL SEE WHY -- HELLO.

A student says HI.

Lorraine says HI.
AND WHICH ONE DID YOU CHOOSE?

The student says I CHOSE WINNIPEG.

Lorraine asks OKAY, WHY IS THAT?

The student says BECAUSE IT'S
FURTHER UP NORTH.
IT'S NORTH OF SAN
FRANCISCO, I THOUGHT.

Stewart says YES, THAT'S TRUE.

The student says AND I WASN'T SURE WHETHER IT
WAS WEST OR EAST OF CHICAGO,
SO I GUESSED.

Stewart says IN FACT, IT'S JUST A
BIT WEST OF CHICAGO.
ALL THREE OF THOSE CITIES ARE
ACTUALLY WEST AND NORTH OF
CHICAGO AND SAN FRANCISCO.
ANY ONE OF THEM
COULD HAVE QUALIFIED.

The student says YEAH.

Stewart continues BUT IT'S NOT WINNIPEG.
SO WE'LL LET YOU
KNOW THAT ONE.
IS THERE ANYBODY
FROM JACK MINER?
I'M KIND OF CURIOUS?

Lorraine says I DON'T HAVE ONE HERE.

Stewart asks NOBODY FROM JACK MINER?
SOMEBODY ELSE?

Lorraine says I DO HAVE SOMEONE
FROM COLLEGE.
EASTER CAN MAYBE SHARE WITH US
WHY, OR WHAT THE ANSWER MIGHT
BE, AND IF WE GO BACK TO THE
QUESTION, WE CAN LOOK AT IT
HERE WHERE IT SAYS...
HELLO, EASTER?

A student says HI.

Lorraine says HI.
AND WHICH ONE DID YOU CHOOSE?

The student says EDMONTON.

Lorraine asks AND WHY EDMONTON?

The student says BECAUSE I DIDN'T THINK THAT
WINNIPEG WAS A VERY BIG CITY.
AND NO ONE WAS LIVING IN
VANCOUVER YET BECAUSE IN THAT
YEAR NOT MANY PEOPLE HAD GONE
TO, AND IT WASN'T REALLY PART
OF CANADA YET.

Lorraine says EXCELLENT.

Stewart says THE ANSWER HAPPENS TO
BE NONE OF THE ABOVE.
SO MOST OF YOU, ACTUALLY,
THE BIGGEST NUMBER DID CHOOSE
NONE OF THE ABOVE, BUT
THAT MEANS IT'S ANOTHER CITY.

Lorraine says AND WE HAVE SOMEONE
FROM JACK MINER.

Stewart says LET'S GO FOR IT.
I'M REALLY CURIOUS TO KNOW WHAT
THEY'LL SAY FROM JACK MINER.

Lorraine says HELLO?

A student says HI.

Lorraine says HI.
WHAT DO YOU THINK
IS THE PLACE?

The student says I HAVE NO IDEA.

Lorraine says YOU'RE NOT SURE.

Stewart says YOU WERE PART OF THE TEAM
THAT DID SOME RESEARCH.
AND I THINK ONE OF THE THINGS
YOU DID, I HAVE IT ON THE
SLATES OVER THERE,
WAS THE POPULATION.
ONE OF THOSE STRANGE
POPULATION FIGURES.
DO YOU REMEMBER THAT?

Lorraine says DO I HAVE THAT HERE?

Stewart says ALMOST THE VERY FIRST SLATE.

The student says WE DON'T KNOW.

Lorraine says OKAY, I'M GOING TO
REFRESH YOUR MEMORY HERE.

She shows a piece of paper written by Stewart. It reads “Dawson City. Population: 1898 – 30000. 1998 – 972.”

Lorraine continues 1898, LOOK AT THE POPULATION.
LOOK AT IT TODAY.
SO WHAT DID IT SAY ABOUT THAT
PARTICULAR CITY IF WE GO BACK
TO THE QUESTION WHERE IT
SAYS IN 1900, WHICH WAS THE
LARGEST CITY WEST OF CHICAGO
AND NORTH OF SAN FRANCISCO.

Stewart says WHAT WOULD YOU GUESS NOW?

The student says DAWSON CITY.

Lorraine says THAT'S RIGHT.
SAY THAT NICE,
LOUD AND CLEAR.

The student says DAWSON CITY.

Lorraine says THAT'S RIGHT.
DAWSON CITY.

Stewart says AS IT TURNS OUT,
THAT'S TRUE.
WINNIPEG, VANCOUVER, EDMONTON
WERE ALL RELATIVELY SMALL
CITIES, AND THEY DIDN'T START
TO REALLY BOOM UNTIL AFTER
THE TURN OF THE CENTURY.
THE LARGEST CITY FOR A VERY
SHORT PERIOD OF TIME WAS
DAWSON CITY DURING THE
HEIGHT OF THE GOLD RUSH.

Lorraine says THAT'S RIGHT.

Stewart continues WHICH IS KIND OF NEAT.
UNLESS WE HAVE SOME CALLS TO
DO WITH QUESTIONS AND ANSWERS,
THIS MIGHT BE A GOOD
TIME TO BID OUR ADIEU.

Lorraine says YES.
AND WE DO HAVE ONE
CALL FROM FLAMBOROUGH.
AND WE'LL SEE IF THEY HAVE
ANY QUESTIONS AS FAR
AS OUR EXERCISES.
HELLO?

The student says I DIDN'T HAVE A QUESTION.

Lorraine says OH, YOU DIDN'T.
OKAY, DO YOU UNDERSTAND THE
EXERCISES FOR THURSDAY?

The student says YEAH.

Lorraine says GREAT.
THANKS VERY MUCH.
OKAY, AND WE SEE WE DON'T
HAVE ANY MORE QUESTIONS.
WE'D LIKE TO THANK YOU FOR
YOUR PARTICIPATION TODAY.
YOU DID VERY WELL.
AND JUST A REMINDER FOR
TOMORROW'S CLASS, THAT YOU
WILL NEED GRAPH PAPER, A
RULER, PENCIL, AND ERASER.
AND WE'LL SEE YOU THEN.
BYE-BYE.

A blue slate appears on screen. It reads “Please remember to log off! Pick up handset. Press pound 7. Press 1 to confirm. Hang up handset. See you next time!”

A slate shows the last question and the final results in a bar graph. 8, 9, 11 and 16 for Winnipeg, Vancouver, Edmonton, and none of the above respectively.
