(music plays)

Against a starry sky with grid lines and a galaxy, a globe spins and a pink gear rotates. At the same time, another pink piece orbits around the globe. A title in yellow letters reads “A World in Motion Two.”

Lorraine appears on screen. She is in her thirties, with long slightly wavy red hair tied-up and bangs. She wears a green blouse and a gold necklace.

She says GOOD MORNING, AND WELCOME
TO TVO'S VIRTUAL CLASSROOM.
TODAY IS LESSON FIVE OF THE
WORLD IN MOTION II PROJECT.
THE AGENDA FOR TODAY, FIRST
THING WE'LL BE DOING IS A
QUICK REVIEW OF THE GEAR
TRAINS AND KNOWING HOW TO
FIGURE OUT THE RATIOS,
FOLLOWED BY MOTORS, AND YOU'LL
HAVE A CHANCE TO DO AN
ACTIVITY DURING THE CLASS
TODAY, SO MAKE SURE YOU HAVE
YOUR MOTORS WITH YOU, AS WELL
AS YOUR KITS.
AS WELL, FOR...
WE'LL TALK QUICKLY ABOUT SOME
SOFTWARE THAT YOU CAN TRY OUT
TO REINFORCE A BETTER
UNDERSTANDING OF MOTORS
AND GEAR TRAINS.
THEN THE HOMEWORK.
NOW, FOR A REVIEW OF LAST
WEEK'S LESSONS AS FAR THE GEAR
TRAINS, I'D LIKE YOU
TO HAVE A LOOK AT THIS.

She shows a homework sheet with a gear train. The first gear is a 10 teeth gear; in the second axle there’s a 10 teeth gear inside a 40 teeth gear and in the third axle there’s a 40 teeth gear.

She says HERE, YOU'LL NOTICE YOU HAVE
SOME GEARS AND IT'S A GEAR
TRAIN BECAUSE, AS WE REMEMBER
ABOUT GEAR TRAINS, YOU HAVE TO
HAVE TWO GEARS AND ONE AXLE,
AND HERE ARE THE TWO GEARS.
NOW, WE HAVE FOUR
GEARS IN ALL.
WHO CAN CALL IN AND LET ME
KNOW HOW I CAN FIGURE OUT THE
GEAR RATIO ON THE SCREEN?
AND A REMINDER TO CALL OUT
BY PRESSING POUND NINE.
AND I'M CALLING
SOMEONE FROM USBORNE.
[phone busy signal]
HELLO?
[phone busy signal]
HELLO.
IS THIS JASON?
JASON FROM JACK MINER, IF YOU
CAN LIFT UP YOUR PHONE, PLEASE.
IF YOUR PHONE IS RINGING,
WE'RE GOING TO TRY HERE
SOMEONE FROM USBORNE, AND
WHILE WE'RE WAITING FOR A
CALL -- HELLO?
HI.
OKAY, WE'RE GOING TO TRY ONE
MORE, BUT WHILE YOU ARE...
WHILE WE'RE WAITING TO HEAR
WHAT THE GEAR RATIO IS, YOU
COULD BE FIGURING IT OUT
YOURSELVES ON A PIECE OF PAPER
BECAUSE THIS WILL HELP YOU FOR
THE NEXT QUESTION, WHICH IS
COMING UP VERY SHORTLY, WHERE
YOU'RE GOING TO REQUIRE YOUR
PHONES TO FIGURE IT OUT.
HELLO.

The caller says HI.

Lorraine says HI, IS THIS JUSTINA?

The caller says YUP.

Lorraine says HELLO, JUSTINA.
CAN YOU HELP ME FIGURE
OUT THE GEAR RATIO?
WHAT DO I NEED TO
KNOW BEFORE ANYTHING?

Justina says FOUR OVER ONE.

The caller says OKAY, AND WHY ARE YOU
SAYING FOUR OVER ONE?
WHICH GEARS ARE
YOU LOOKING AT?
LIKE, FIRST OF ALL, I HAVE TO
KNOW WHICH ONE IS MY DRIVE
GEAR, SO WHICH ONE ARE YOU
CHOOSING AS A DRIVE GEAR?

Justina says TEN.

Lorraine says OKAY, VERY GOOD.
SO WE'LL...
AS LONG AS WE'RE ALL CLEAR,
WE'RE CHOOSING THIS AS OUR
DRIVE GEAR.
THAT'S GREAT.
AND SO WHAT DO
WE NEED TO KNOW?
BECAUSE YOU WERE CORRECT.
YOU SAID FOUR TO ONE, BUT WHAT
ARE YOU DOING TO FIGURE OUT
FOUR TO ONE?
I'LL HELP YOU OUT HERE.

She writes “rotations A” on the sheet.

Justina says THE SMALL ONE WILL
TURN FOUR TIMES AND...

Lorraine says THAT'S RIGHT.
OKAY, SO YOU'RE TALKING
ABOUT THE ROTATIONS OF A
AND TO THE B GEAR.
SO THIS IS YOUR A GEAR, THIS
IS THE B AND THAT WILL BE C.

She writes A on the axle with the 10 teeth gear, B on the axle with the 10 teeth inside the 40 teeth and C on the axle with the 40 teeth gear alone.

Lorraine says OKAY, SO TRY THAT AGAIN.
ROTATIONS OF A WILL BE
HOW MANY TIMES TO THIS...?

Justina says FOUR.

Lorraine says THAT'S RIGHT.
FOUR, AND HOW MANY TIMES
WILL THE 40-TOOTH GEAR GO?

Justina says ONE.

Lorraine writes down “A over B equals 4 over 1.”

Lorraine says ONE, VERY GOOD.
HOW ABOUT...
NOW WHAT ARE WE
SUPPOSED TO DO?
AND I WILL GET OUT OF THE
PICTURE HERE SO WE CAN SEE.
NOW WE'RE SUPPOSED TO DO
THE ROTATIONS OF THIS,
THE B GEAR TO THE C,
SO WHAT WILL IT BE?
HELLO?

Justina says THE SAME.

Lorraine says VERY GOOD, THAT'S RIGHT,
BECAUSE THIS WILL GO AROUND
FOUR TIMES WHILE THIS
ONE WILL GO ONCE.
NOW, HOW DO I FIGURE
OUT THE GEAR RATIO?
DO YOU REMEMBER FROM
THE LAST LESSON?
WHAT AM I SUPPOSED
TO DO WITH THESE TWO?

She writes “B over C equals 4 over 1.”

Justina says TIMES IT.

Lorraine says THAT'S RIGHT.
SO IF WE GO FOUR OVER
ONE TIMES FOUR OVER ONE,
WHAT DO WE GET AS
A GEAR RATIO?

Justina says SIXTEEN OVER ONE.

Lorraine says THAT'S CORRECT, 16 OVER ONE.
SO WHAT DOES THAT TELL ME?
WHAT IS GOING 16 TIMES
WHEN WE LOOK AT THIS?

Justina says THE DRIVE GEAR.

Lorraine says THAT'S RIGHT.
SO THIS WILL GO 16 TIMES WHILE
THIS GOES HOW MANY TIMES?

Justina says ONCE.

Lorraine says ONCE.
SO THAT'S QUITE THE RATIO
WHEN WE THINK OF 16 TO ONE.
WHEN WOULD WE USE A
GEAR RATIO LIKE THAT?
LET'S PRETEND WE'RE
ON A BICYCLE.
WHEN WE WOULD USE SOMETHING
WHERE YOUR FEET ARE DOING
16 TIMES BUT YET, YOUR
WHEEL TURNS ONLY ONCE?

Justina says WHEN YOU'RE
GOING UP THE HILL.

Lorraine says THAT'S CORRECT.
VERY GOOD.
YOU DID VERY WELL, JUSTINA.
THANK YOU VERY MUCH.
BYE-BYE.
NOW, FOR THE REST OF YOU, I'M
GOING TO GIVE YOU ANOTHER
EXAMPLE, AND WHAT I'D LIKE
FROM YOU IS TO LOOK AT IT,
WRITE IT DOWN ON A PIECE OF
PAPER, TRY AND FIGURE OUT THE
DIFFERENT STEPS, AND THEN I
WILL PUT IT UP ON A SCREEN
WHERE YOU'RE GOING TO
ANSWER WITH YOUR PHONES
WHICH IS THE CORRECT ANSWER.
SO LET'S LOOK AT
THIS GEAR TRAIN.

She shows another gear train with a 15 teeth gear in the first axle, a ten inside a 30 teeth gear in the second and a 50 teeth gear in the third axle. She writes “drive” in the first axle and the letters A, B and C from left to right.

Lorraine says YOU HAVE...
AND THIS, I'M TELLING YOU NOW,
IS YOUR DRIVE GEAR, OKAY?
SO YOU HAVE A 15 TO A 30,
AS WELL AS A 10 TO THE 50,
SO WHAT WILL BE YOUR ANSWER?
WRITE IT DOWN, AND I'LL GIVE
YOU A FEW MINUTES, THEN I WILL
TAKE THIS AWAY.
NOW I'M GOING TO SHOW YOU ON
THE SCREEN HERE WHERE YOU CAN
USE YOUR PHONES TO
ANSWER THIS QUESTION:

Question number 1 appears on screen. It reads “drive gear: 15 teeth. Driven gear: 30 teeth. Drive gear: 10 teeth. Driven gear: 50 teeth. What is the gear ratio? 1- 5 to 1; 2- 10 to 1; 3- 1 to 10 and 4- 1 to 5.”

Lorraine says WHICH IS EXACTLY WHAT YOU
HAD A CHANCE TO SEE RIGHT
OVER HERE.
NOW, WHAT IS THE GEAR RATIO?
IS IT FIVE TO ONE,
10 TO ONE, AND SO ON?
OKAY.
SEE IF WE CAN GET 75, GREAT.
A FEW MORE SECONDS.
SO WE CAN SEE 83 PERCENT
OF YOU HAVE ANSWERED, 85.

The results appear in a bar graph. 19 students pressed option 1, 28 students pressed option 2, 9 students pressed option 9 and 5 students pressed option 5.

Lorraine says OKAY, NOW, FROM WHAT WE
CAN SEE HERE, THERE'S
APPROXIMATELY 19 OF YOU THAT
BELIEVE IT IS NUMBER ONE,
A RATIO OF FIVE TO ONE.
THERE IS A GREATER MAJORITY
THAT BELIEVE IT'S 10 TO ONE,
THE RATIO.
SOME OF YOU THINK IT'S ONE
TO 10 AND SOME OF YOU,
ONE TO FIVE.
WELL, LET'S HAVE A LOOK AT THE
EXERCISE I HAD HERE, AND HOW
ABOUT IF YOU CALL IN BY
PRESSING POUND NINE AND SHARE
WITH ME WHY YOU PICKED THE
ANSWER YOU DID AND SEE IF WE
CAN FIND THE CORRECT ANSWER.
SO HELP US OUT BY PRESSING
POUND NINE, AND I'M CALLING
EITHER SARAH OR BETHANY
FROM USBORNE CENTRE.
HELLO.

The caller says HELLO?

Lorraine says HI, AND WHO AM I SPEAKING TO?

The caller says BETHANY.

Lorraine says HI, BETHANY.
CAN YOU HELP US?
DID YOU FIGURE THIS ONE?

Bethany says WELL, THE 15 TO 30.

Lorraine says OKAY.

Bethany says THE DRIVER WILL GO TWO TIMES
AND THE DRIVEN WILL GO ONE.

Lorraine says THAT'S RIGHT.
SO YOU'RE SAYING THIS WILL
TURN TWO TIMES AS THE 30-GEAR
WILL TURN ONCE, VERY GOOD.
SO THIS SHOULD BE, LIKE,
TWO OVER ONE, GREAT.
AND WHAT IS IT, THE...
AS FAR AS THE B TO THE C?
She writes down “A over B equals 2 over 1.”

Bethany says IS THAT THE 10 TO 50?

Lorraine says THAT'S RIGHT, 10 TO 50.

Bethany says WELL, 10 WILL GO FIVE TIMES.

Lorraine says THAT'S RIGHT.
THIS ONE WILL TURN FIVE,
WHILE THE 50 TURNS...?

Bethany says AND THE 50 WILL TURN ONCE.

Lorraine says PERFECT!
SO YOU HAVE FIVE TO ONE.
NOW, WHAT DO I DO WITH
THESE TWO NUMBERS?

She writes “B over C equals over ).”

Bethany says PARDON?

Lorraine says THESE TWO RATIOS, WHAT DO I
DO WITH THEM NOW TO FIGURE
OUT THE...

Bethany says MULTIPLY THEM.

Lorraine says THAT'S RIGHT.
SO WE'RE GOING TO SAY TWO
OVER ONE TIMES FIVE OVER ONE,
AND WHAT DO YOU GET?

Bethany says TEN OVER ONE.

Lorraine says YEAH, VERY GOOD.
10 OVER ONE.
NOW, WHAT DOES THAT MEAN WHEN
I LOOK BACK AT MY GEAR TRAIN?

Bethany says THAT THE DRIVER WILL GO 10
TIMES AND THE DRIVEN WILL
GO ONCE.

Lorraine says ONCE, EXACTLY.
AND ONCE AGAIN, WHEN WOULD
WE USE A RATIO 10 TO ONE?

Bethany says FOR GOING UP A HILL.

Lorraine says YEAH, THAT'S RIGHT,
GOING UP A HILL.
VERY GOOD.
THANKS VERY MUCH.
OKAY, AT THIS POINT YOU'RE
GOING TO BE WATCHING A VIDEO
FOR APPROXIMATELY TWO MINUTES
ON DIFFERENT TYPES OF MOTORS,
AND WHAT I WANT FROM
YOU IS THE FOLLOWING:

A slate appears with the caption “Make a list of all the machines that are motorized.”

Lorraine says SO, AGAIN, WHEN YOU'RE WATCHING
THE VIDEO, YOU'RE GOING TO
MAKE A LIST OF ALL THE
MACHINES THAT ARE MOTORIZED,
AND RIGHT AFTER THE VIDEO, IF
YOU CAN CALL IN BY PRESSING
POUND NINE TO SHARE SOME
OF THE MACHINES YOU HAVE
ON YOUR LIST.
OKAY, AND ENJOY THE VIDEO.

The video shows images of an electric sander, motorbike races, a car accelerating, a bulldozer being driven through the woods, a man driving a four wheeler, two people driving snow mobiles and a man turning on a heater.

Lorraine says NOW, I'D LIKE TO HEAR FROM
YOU, WHAT MACHINES DID YOU SEE
THAT WERE MOTORIZED?
HELLO.
BRANDI, I BELIEVE,
FROM JACK MINER.
HELLO?
BRANDI GOLDEN, IF YOUR PHONE
IS RINGING, COULD YOU LIFT
IT UP, PLEASE?
WE'LL TRY SOMEONE FROM
SOUTHWOOD PARK, SO MAKE SURE
YOU HAVE A LIST OF ALL THE
DIFFERENT MACHINES YOU'VE SEEN
THAT WERE MOTORIZED
AND SHARE THEM WITH US
BY PRESSING POUND NINE.
HELLO?

The caller says HELLO?

Lorraine says HI.
SO WHAT CAN YOU TELL US?
WHICH MACHINES DID YOU SEE?

The caller says A SANDER.

Lorraine says GREAT.
AND WHAT WAS THE
SANDER USED FOR?

The caller says SANDING CARS.

Lorraine says GREAT.
CAN YOU NAME ME ANOTHER ONE?

The caller says A MOTORCYCLE.

Lorraine says MOTORCYCLE.
AND HOW ABOUT ONE MORE?

The caller says A CAR.

Lorraine says A CAR, GREAT.
THANKS VERY MUCH.

The caller says OKAY, BYE.

Lorraine says BYE.
AND LET'S TRY SOMEONE
HERE FROM USBORNE CENTRE.
HELLO.

The caller says HELLO?

Lorraine says HI, CAN YOU SHARE WITH ME SOME
MACHINES THAT WERE MOTORIZED?

The caller says A FOUR-WHEELER.

Lorraine says OKAY, A FOUR-WHEELER.
TWO MORE.

The caller says SNOWMOBILES.

Lorraine says

The caller says AND THE AIRPLANE.

Lorraine says AIRPLANE, YES.
WHAT TYPE OF AIRPLANE?
WHAT DID IT HAVE ON ITS...
WHERE DOES IT LAND?

The caller says IN THE WATER.

Lorraine says THAT'S RIGHT.
IN THIS CASE, IT WAS
AN ICE LAKE THERE.
GREAT, THANKS VERY MUCH.
WE'LL TRY ONE MORE PERSON.

The caller says HELLO?

Lorraine says HI.
CAN YOU SHARE US TWO MORE
MACHINES THAT YOU HAD
A CHANCE TO SEE?

The caller says YEAH, THERE WAS A BOAT.

Lorraine says OKAY, AND WHAT ELSE?

The caller says A CRANE.

Lorraine says OKAY, CRANE.
GREAT.
WELL, THANKS VERY MUCH.

The caller says BYE.

Lorraine says BYE.
SO AS YOU CAN TELL, WHEN IT
COMES TO MOTORS, THERE'S A
GREAT VARIETY OF THEM.
SOME MOTORS ARE QUITE SMALL,
SOME ARE QUITE LARGE, AND I'M
SURE SOME OF YOU HAVE OTHER
MACHINES THAT YOU'VE SEEN
IN THE VIDEO THAT WE
DID NOT WRITE DOWN.
BUT THE KEY HERE IS THE IDEA
OF THE MOTORS BEING ALL
DIFFERENT SIZES.
THE ONES THAT YOU HAVE IN YOUR
KIT LOOKS LIKE THIS, SO YOU
WILL NEED IT IN A FEW MINUTES
WHEN YOU'LL BE WORKING
ON YOUR EXERCISES.
AND THE MOTOR IS QUITE SMALL
FOR YOUR KIT, AND I'M GOING TO
SHOW YOU HOW YOU MOUNT THIS
PARTICULAR MOTOR ON YOUR
VEHICLE FRAME.
SO IF SOMEONE IN YOUR GROUP
HAS IT HANDY, THAT WOULD BE
GREAT, YOU CAN TRY IT OUT
WHILE I'M DOING IT IN FRONT OF
YOU, AND THIS WAY, YOU'LL BE
READY FOR THE EXERCISE TODAY.
NOW, THIS MOTOR WILL
GO INSIDE THE FRAME.
THIS WAY, YOU CAN HAVE THE
SHAFT OF THE MOTOR STICKING
OUT LIKE THIS, OKAY?
AND I'M JUST CHOOSING,
TO PUT IT OVER HERE.
[clicking]
NOW, YOU'RE GOING TO NOTICE
THE TWO NUTS OVER HERE HAVE TO
BE STICKING OUT DIAGONALLY.
NOW, I CAN MOVE THIS MOTOR
AROUND AND PLACE IT ANYWHERE,
BUT THE KEY IS ONCE YOU HAVE
A GEAR TRAIN, YOU'RE GOING TO
HAVE TO WORK IT OUT WHERE IT
IS PLACED WHEREVER YOUR DRIVE
GEAR IS OF YOUR
GEAR TRAIN, OKAY?
SO LET'S PUT IT OFF HERE TO
THE SIDE, AND YOU'RE GOING TO
NEED YOUR WING NUTS OVER HERE
AND THE WING NUT JUST TURNS
LIKE THIS.
SO IF YOU COULD
BE DOING THE SAME.
THERE WE GO, TIGHTEN IT UP
JUST A TAD, AND THEN WE'LL PUT
THE OTHER WING NUT
ON THE OTHER SIDE.
AND THIS KEEPS YOUR MOTOR
IN PLACE JUST LIKE THAT.
SO NOW I CAN PLAY IN THE
BACK HERE AND IT'S STURDY.
WHEN I HOOK UP MY MOTOR TO THE
ADAPTOR, IT'S THE SHAFT HERE
THAT WILL BE SPINNING
VERY QUICKLY, OKAY?
AND YOU'LL NOTICE IN YOUR
KIT, YOU HAVE A 15-TOOTH GEAR
THAT'S CONNECTED TO A DRIVE
COLLAR AND IT'S STUCK THERE,
THIS PARTICULAR GEAR, AND
THE REASON FOR THAT IS IT'S
EXCELLENT FOR THE MOTOR SHAFT
AND YOU CAN PUT IT RIGHT ON.
AND YOU'LL NOTICE WHERE
THERE'S A BLACK CIRCLE.
IF I COME IN A TAD, THERE'S
A BLACK CIRCLE THERE.
THAT'S WHERE THERE'S...
YOU PUT THAT PART IN THE
INDENTATION HERE OF THE SHAFT,
SO YOU CAN STICK IT ON A
LITTLE BIT BETTER LIKE THAT
AND THEN IT'S STURDY.
IT'LL STAY ON AND
WON'T COME OFF.
OKAY?
YOU CAN PUT OTHER GEARS, IT
DOESN'T MATTER, BUT IT'S JUST
IT SEEMS LIKE THE 15-TOOTH
GEAR WITH THE DRIVE COLLAR IS
THE BEST ONE.
BUT IT DEPENDS ON YOUR GEAR
TRAIN, WHATEVER YOU CHOOSE.
NOW, IF THIS IS YOUR DRIVE
GEAR, WELL THEN YOU'RE GOING
TO HAVE TO CONNECT ALL YOUR
GEAR TRAIN ACCORDINGLY, OKAY?
NOW, AT ANY TIME WHILE I'M
DOING THIS DEMONSTRATION, IF
YOU HAVE ANY QUESTIONS, PLEASE
FEEL FREE TO PRESS POUND NINE,
BECAUSE I WILL NOW SHOW YOU
HOW TO MOUNT THE WHEELS ONTO
THE VEHICLE FRAME, AND THEN
I'M GOING TO BE ASKING YOU TO
DO AN EXERCISE WHICH WILL
COMBINE ALL THE GEAR TRAIN,
THE MOTOR AND THE
WHEELS, AND IT'S...
I'M SURE YOU'LL
ENCOUNTER SOME PROBLEMS.
I CERTAINLY DID, AND
IT'S KIND OF FUN.
THROUGH THE PROBLEMS,
YOU LEARN A LOT.
OKAY, SO IF WE LOOK AGAIN AT
OUR VEHICLE FRAME, YOU WILL
NOTE THAT THE AXLES FOR THE
WHEELS, THERE'S A SECTION HERE
THAT THE ENDS OF THE AXLES ARE
MORE NARROW THAN YOUR REGULAR
AXLES THAT YOU SEE FOR YOUR
GEARS, AND THE REASON FOR
THAT, IT'S SO THAT THE WHEELS
WILL FIT PROPERLY, OKAY?
AND, ONCE AGAIN, YOU'LL HAVE
TO PUT YOUR -- AND I WILL TAKE
THIS ONE OFF -- YOUR AXLE
BUSHINGS IN YOUR FRAME LIKE
YOU DID PREVIOUSLY, AND ONCE
AGAIN, IT'S THE NARROW PART
THAT SNAPS IN AND THE
LONGER PART STAYS INSIDE.
AND THE REASON WHY I'M
CHOOSING THE LOWER ONE HERE,
IT'S EASIER FOR MY WHEELS
TO FIT IN, SO IF I GO RIGHT
ACROSS LIKE THIS, OR I
CAN GO TO THE OTHER END.
I GO THROUGH MY AXLE
BUSHINGS LIKE THIS.
THEN YOU WILL PUT SOME RUBBER
STOPPERS WHEREVER YOU FEEL
WILL BE THE BEST PART TO STOP
THE WHEELS FROM MOVING AROUND,
OR THE AXLE FROM MOVING.
OKAY, SO YOU COULD PUT A
RUBBER STOPPER AND THEN
ANOTHER RUBBER STOPPER
WHERE IT LOOKS LIKE THIS...
OKAY, RUBBER STOPPER AT THE END
AND ANOTHER RUBBER STOPPER.

She shows a vehicle frame with the 4 wheels in place and the small motor attached to the driver gear in the gear train.

Lorraine says NOW, TO PLACE THE WHEELS...
THESE ARE YOUR WHEELS.
THERE'S A SECTION HERE, IF I
COME IN CLOSER, WHERE THERE'S
JUST A LITTLE HOLE, IF YOU SEE
THAT, AND THEN THERE'S ANOTHER
ONE HERE WHERE IT
STICKS OUT A BIT.
IT'S KIND OF HARD TO TELL ON
THE SCREEN, BUT THE PART THAT
STICKS OUT IS THE PART YOU'RE
GOING TO PUT INTO THE AXLE,
OKAY, LIKE THAT.
AND YOU HAVE TO PUT A LITTLE
BIT OF PRESSURE IN ORDER TO
FIT IT IN AND JUST TURN THE
WHEEL LIKE THAT AND THEN PLACE
THE OTHER ONE.
OKAY?
NOW, I NOTICE THERE'S NO ONE
CALLING IN AT THIS POINT,
SO I'M ASSUMING WE DO
NOT HAVE ANY QUESTIONS.
ANOTHER PART THAT YOU WILL
HAVE TO HAVE FOR YOUR KIT -
AND THIS, MAYBE THE TEACHER
WILL WANT TO HAVE IT IN ONE
SECTION OF THE ROOM --
AND IT IS THE ADAPTOR.
AND I WILL EXPLAIN
THAT IN A MINUTE.
THE ADAPTOR LOOKS
LIKE THIS, OKAY?
AND THE END OF THE ADAPTOR
IS AS FOLLOWS, OKAY?

She shows a female connector.

Lorraine says AND THE END OF THE MOTOR IS
LIKE THAT.

She shows a male connector.

Lorraine says AND YOU ARE TO PLUG
IN -- AND I'VE PUT AN EXTENSION
ON MINE -- BUT YOU CAN PLUG IN
THE ADAPTOR AND AT ANY TIME
WHEN YOU'RE WANTING TO TRY OUT
THE GEAR TRAIN OR THE MOTOR OR
THE WHEELS AND SO ON, YOU CAN
DO SO BY JUST PLUGGING IT IN,
OR PRESSING THIS IN OR TAKING
IT OUT, WHICH I WILL
SHOW YOU IN A MOMENT.
NOW, TO KEEP IN MIND, BECAUSE
YOU'RE GOING TO HAVE AN
EXERCISE FOR ABOUT, CLOSE TO
13 MINUTES, WHERE I'M GOING TO
ASK YOU TO DO SOMETHING
SIMILAR TO THIS, BUT YOU
CHOOSE YOUR OWN GEAR TRAIN
AND THIS IS THE GEAR TRAIN.
I HAVE THE WHEELS ON, AND
AS WELL, I HAVE MY MOTOR
CONNECTED, AND I WILL BRING IT
UP JUST A TAD CLOSER LIKE THIS.
YOU WILL NOTE THAT ONE OF YOUR
GEARS IN THE GEAR TRAIN HAS
TO BE CONNECTED TO THE
WHEEL AXLE, OKAY?
AND BY DOING SO,
THIS WILL THEN...
YOUR GEAR TRAIN WILL ROTATE,
ROTATING THE WHEELS, IS THE
IDEA HERE, OKAY?
AND ALSO, YOUR MOTOR HAS TO BE
CONNECTED TO THE DRIVE GEAR.
SO SOMETIMES...
IN MY CASE, I JUST PLACED THEM
A LITTLE DIFFERENTLY HERE,
AND TO KEEP THAT IN MIND.
I WANT YOU NOW...
AND YOU'RE GOING TO HAVE A
CHANCE HERE TO LOOK AT HOW,
IF YOUR TEACHER HAS THE ADAPTOR
IN THE CLASSROOM, AT ONE
POINT, YOU SAY, “OKAY, LET'S
SEE IF OUR GEAR TRAIN ACTUALLY
WORKS,” WELL YOU'RE GOING TO
NOTICE ON THE SIDE HERE
THERE'S A LITTLE
POSITIVE AND A NEGATIVE.
IT'S A LITTLE BIT DIFFICULT TO
SEE, BUT THERE'S A POSITIVE
AND NEGATIVE THERE AND THERE'S
A POSITIVE AND NEGATIVE.
IF I PUT THE TWO POSITIVES
TOGETHER, THIS IS WHAT HAPPENS
TO MY VEHICLE.

The vehicle moves.

Lorraine says HERE WE GO.
SEE IT MOVING?
NOW, IF I SWITCH IT AND I PUT
THE NEGATIVE WITH THE POSITIVE
AND POSITIVE WITH NEGATIVE,
GUESS WHAT'S GOING TO HAPPEN.
IT GOES THE REVERSE, OKAY?
SO ONCE AGAIN, IF I PUT
POSITIVE AND POSITIVE
TOGETHER, IT GOES ONE WAY.
AND IF I PUT IT THE
OPPOSITE WAY, IT WILL TURN.
GO BACKWARDS, OKAY?
AT THIS POINT YOUR
EXERCISE WILL BE:

A slate appears with the caption “Exercise. 1– Build gear train with motor and wheels. 2- Make a list of problems slash solutions. 3- Safety!!! 4- Call in to share with classes (pound 9) Back in 13 minutes.”

Lorraine says AND IF YOU D-ON'T GET IT
ALL DONE, THAT'S OKAY
BECAUSE THERE'S GOING
TO BE PROBLEMS.
SOMEBODY IN YOUR GROUP THAT'S
ACTUALLY WRITING DOWN, BEING
A SECRETARY, AND MAYBE THE
PERSON THAT'S PLAYED WITH THE
MATERIALS THE MOST SHOULD
BE THE SECRETARY TODAY.
THAT WAY IT GIVES THE
OTHER PEOPLE A CHANCE
TO PLAY WITH
THE MATERIALS.
SO MAKE A LIST OF THE
PROBLEMS AND SOLUTIONS.
I KNOW I HAD SOME PROBLEMS AND
IT WAS KIND OF FUN BECAUSE
NOW I'LL NEVER DO THOSE
PROBLEMS AGAIN BECAUSE
I FOUND A SOLUTION.
THEN TO ALWAYS KEEP IN MIND
SAFETY, WATCH THE MATERIALS,
MAKE SURE SOMEBODY IN YOUR
GROUP IS KEEPING THAT IN MIND,
TO ENCOURAGE ALL TO BE SAFE.
AND YOU'LL HAVE APPROXIMATELY
13 MINUTES TO WORK ON THIS.
I NOTICE A FEW CALLS HERE.
I'LL TAKE IN A FEW OF THE
CALLS WHILE THE REST OF YOU
GET STARTED.
CALLING SOMEONE
FROM SAINT CHARLES.
HELLO.

The caller says HOW DO YOU KNOW EXACTLY
WHERE TO PUT THE MOTOR?

Lorraine says WELL, THAT'S A GREAT QUESTION
AND THAT'S WHY I DON'T...
WITHOUT ME TELLING YOU EXACTLY
WHERE TO PUT IT, IT'S A GOOD
IDEA TO PLACE IT WHEREVER
YOUR GEAR TRAIN IS.
SO ONE THING YOU CAN KEEP IN
MIND IS MAYBE PLACING THE
WHEELS FIRST, COMING UP WITH A
GEAR TRAIN AND THEN WHEREVER
YOUR DRIVER IS, THEN PUT THE
MOTOR BEHIND THE DRIVER.
IT'S ENTIRELY UP TO YOU, BUT I
DEFINITELY HAD A FEW PROBLEMS
AT FIRST AND NOW I HAVE
A FEW TRICKS FOR MYSELF,
BUT I WANT YOU TO TRY
AND FIGURE THAT OUT.
OKAY?

The caller says OKAY, THANKS.

Lorraine says GREAT, THANKS.
AND I'LL TAKE...
LET'S SEE NOW, THE
CALLS ARE GOING...
LET ME TRY ONE FROM
SAINT JEAN DE BREBEUF.
HELLO.
KYLA OR VINCE FROM SAINT
JEAN DE BREBEUF, HELLO.
OKAY, AND...
HELLO?
I BELIEVE I HAVE ONE MORE
CALL FROM SAINT CHARLES.
THE REST OF YOU, GET STARTED.
YOU HAVE 13 MINUTES.

The caller says HI.

Lorraine says HI.
YOU HAVE A QUESTION?

The caller says LIKE, I FORGOT... I
DON'T KNOW WHAT TO SAY.

Another student says I FORGOT ABOUT MINE.

Lorraine says WHAT DO YOU MEAN YOU
FORGOT ABOUT YOURS?
YOU FORGOT YOUR QUESTION?

The caller says YEAH.

Lorraine says OKAY, DO YOU UNDERSTAND THE
EXERCISE FOR THE NEXT...
ABOUT, APPROXIMATELY
10 MINUTES?

The caller says YEAH.

Lorraine says GREAT.
OKAY, WELL LOOK FORWARD TO
HEARING FROM YOU AFTERWARDS.

The caller says OKAY.

Lorraine says
BYE-BYE.

The caller says THANKS.

Lorraine says OKAY, I'LL PUT BACK UP WHAT
IT IS YOU'RE SUPPOSED TO DO
FOR YOUR EXERCISE, AND THEN
I'LL BE LOOKING FORWARD TO
HEARING WHAT SOME OF YOUR
PROBLEMS WERE, SOME OF YOUR
SOLUTIONS AND SOME
OF YOUR SUCCESSES.
HAVE FUN.

The exercise slate appears on screen again.

Lorraine says I'LL BE TAKING A FEW CALLS AT
THIS POINT TO HELP YOU OUT,
BECAUSE I NOTICE A FEW
OF YOU ARE CALLING IN.
HI.

The caller says HELLO?

Lorraine says HI.
YOU HAVE A QUESTION FOR ME?

The caller says YEAH.
WE WERE WONDERING, BECAUSE WE
DON'T HAVE OUR KITS WITH US...
WHAT MATERIALS SHOULD WE BE
BRINGING TO THESE CLASSES?

Lorraine says WELL, IN A CASE LIKE THIS,
YEAH, IT WOULD BE GREAT...
IS IT FAR AWAY, THE KIT?
LIKE, COULD YOU NOT
GO GET THEM OR...

The caller says NO.

Lorraine says OKAY, HOW ABOUT EVEN
IF YOU DON'T HAVE THE KIT
THERE, MAYBE AS GROUPS,
WHAT YOU CAN DO IS MAKE
A DESIGN OF IT.
IF YOU USE YOUR DESIGN LOG,
TRY TO VISUALIZE WHAT IT COULD
LOOK LIKE AND WHERE
YOU WOULD PLACE THINGS.
WANT TO DO THAT?

The caller says OKAY.
GREAT.
BUT FROM NOW ON, WE SHOULD
BE BRINGING OUR KITS, RIGHT?

Lorraine says I USUALLY MENTION IT THREE
MINUTES BEFORE THE LESSON IF
YOU DEFINITELY
NEED IT, OR IF...
NEXT LESSON, YOU WON'T NEED IT
BUT MAYBE IF YOU'RE WORKING ON
THE EXERCISE DURING THE WEEK,
ON THURSDAY AT THE BEGINNING
OF THE LESSON, I WILL ASK
IF YOU'VE HAD ANY PROBLEMS.
SO IF YOU HAVE A CHANCE TO
DO THIS DURING THE WEEK,
ON THURSDAY, I CAN ANSWER
ANY OF YOUR QUESTIONS.

The caller says OKAY, THANKS.

Lorraine says APPRECIATE THAT.

The caller says BYE.

Lorraine says THANKS, BYE.
HELLO.
SOMEONE FROM SOUTHWOOD PARK,
YOUR PHONE'S RINGING,
IF YOU CAN LIFT
IT UP, PLEASE.
HELLO?

The caller says HELLO?

Lorraine says HI, YOU HAVE A
QUESTION FOR ME?

The caller says NO, IT WAS SOMEBODY ELSE
THAT DIALLED IN, SORRY.

Lorraine says NO PROBLEMS.
OKAY, ARE YOU HAVING FUN?

The caller says YUP.

Lorraine says GREAT.
AND SOMEONE FROM
SAINT JEAN DE BREBEUF.
HELLO.

The caller says HOW COME THE CAR MAKES SO
MUCH NOISE WHEN YOU PLUG IT IN?

Lorraine says IS IT MAKING A LOT OF NOISE,
AS IN CAN I KIND OF HEAR IT OR
IS IT FAR AWAY FROM THE PHONE?

The caller says PARDON ME?

Lorraine says IF YOU...
THE NOISE SHOULD BE
APPROXIMATELY THIS LOUD,
“NNNNNAAAA,” LIKE THAT.
THAT'S IT.

The caller says OH.

Lorraine says IS THAT WHAT YOU'RE HEARING?

The caller says YEAH.

Lorraine says YEAH, IT'S BECAUSE THE MOTOR
IS TURNING SO QUICKLY,
IT MAKES A NOISE.
JUST LIKE OUR VEHICLES, LIKE
IN A CAR, IT MAKES QUITE A BIT
OF NOISE WHEN YOU START THE
ENGINE, WELL THIS ONE'S...

The caller says YEAH, BUT OURS DOESN'T
MAKE THAT MUCH NOISE.

Lorraine says IT DOESN'T?
WELL, GOOD.
MAYBE IT'S BECAUSE THE WAY
YOUR CLASSROOM, THE ACOUSTICS
ARE A LITTLE DIFFERENT.

The caller says OKAY.

Lorraine says OKAY?

The caller says THANK YOU.

Lorraine says THANKS.
OKAY, BYE.

The caller says BYE.

Lorraine says AND SOMEONE AGAIN FROM
SAINT JEAN DE BREBEUF.
HELLO, SOMEONE FROM SAINT JEAN
DE BREBEUF, IF YOUR PHONE'S
RINGING, IF YOU CAN
LIFT IT UP, PLEASE.
CHRISTINA OR JOY.
HI.
YOU HAVE APPROXIMATELY TWO
MORE MINUTES, SO MAKE SURE YOU
WRAP UP AT THIS POINT SO
YOU'LL BE READY IN TWO MINUTES.
THANKS.
HI.
AT THIS POINT, I'D LIKE TO
HEAR FROM YOU BY PRESSING
POUND NINE TO SHARE WITH
US SOME OF YOUR PROBLEMS,
SOME OF YOUR SOLUTIONS, SOME
SUCCESSES, AND YOU'VE PROBABLY
NOTICED, 13 MINUTES
ISN'T VERY LONG.
THIS IS WHY IT'LL BE PART OF
YOUR EXERCISE FOR THIS WEEK
AS WELL.
I KNOW IT TOOK ME A LITTLE
WHILE OVER THE WEEKEND TO HAVE
SOME FUN PLAYING WITH THIS,
AND LIKE TO HEAR FROM YOU.
HELLO.

The caller says WE WERE JUST WONDERING IF...
FOR MAKING THE CARS, IS
IT OKAY IF WE MAKE, LIKE,
THREE-WHEELERS AND THAT?
LIKE, DOES IT MATTER HOW
MANY WHEELS IT HAS, OR NO?

Lorraine says IT'S ENTIRELY UP TO
YOU AND YOUR CLASS.
IF YOU FEEL THE THREE-WHEELER
WILL DO THE EFFECT OF WHAT
YOU WANT, GO AHEAD.
BUT IN...
IT'S PROBABLY A LITTLE BIT
EASIER FOR THE BALANCING IS
TO HAVE THE FOUR.
BUT THAT'S ENTIRELY UP TO YOU.

The caller says OKAY.
THANK YOU.

Lorraine says OKAY, GREAT.
AND I'M GOING TO TRY
SOMEONE FROM USBORNE.
HI.

The caller says DID YOU WANT TO KNOW
ABOUT OUR PROBLEMS?

Lorraine says YEAH, SURE.

The caller says OKAY.
OUR PROBLEM WAS THAT WE
COULDN'T FIND THE RIGHT HOLE
TO PUT THE WHEELS IN TO
CONNECT TO THE TRAIN.

Lorraine says AHA, WHY?
WHAT'S HAPPENING?
WHAT ARE YOU NOTICING?

The caller says THAT THEY WEREN'T EQUAL.

Lorraine says THAT'S RIGHT, AND I HAVE TO
SAY, I HAD THE EXACT SAME
PROBLEM WHILE I WAS TRYING TO
DO IT, AND WHAT DO YOU THINK
MIGHT BE A SOLUTION TO THAT?

The caller says TRIAL AND ERROR.

Lorraine says OKAY, DEFINITELY.
AND WHAT I ENDED UP DOING --
DID YOU END UP FIGURING
OUT A SOLUTION, OR...?

The caller says YEAH, THAT'S WHAT WORKED.
WE EVENTUALLY FOUND THE SPOT.

Lorraine says OKAY, AND WHERE IS YOUR SPOT?

The caller says THE BOTTOM ROW, FIVE IN.

Lorraine says OH, OKAY, SO OBVIOUSLY...
THEN YOUR LAST DRIVEN GEAR IS
CONNECTED TO THE WHEEL THEN?

The caller says YUP.

Lorraine says WHEEL GEAR?
OKAY, EXCELLENT.
AND MYSELF, THAT'S
EXACTLY WHAT I DID.
I PUT IT ON THE BOTTOM ROW AS
WELL, AND WHAT I'VE DONE, IF
WE LOOK AT THE GRAPHICS
CAMERA HERE, I DID THE SAME.
AND MY GEAR, THE 45 GEAR'S
UNDERNEATH, BUT IT WAS A CLOSE
CALL AS FAR AS THE GEAR
NOT TOUCHING THE BOTTOM.
GREAT.
WELL, THANKS.

The caller says BYE.

Lorraine says BYE.
NOW, WE HAVE HERE AS WELL
SOMEONE FROM SAINT CHARLES.
I FOUND AS WELL SOME OF THE
PROBLEMS, WHILE WE'RE WAITING
FOR THE CALL, IS I HAD
TO PUT TWO OF MY GEARS
CLOSELY TOGETHER LIKE THIS,
AND THEY DO FIT NICELY,
WHERE I DIDN'T USE A DRIVE
COLLAR IN BETWEEN, BECAUSE
I DIDN'T HAVE THE SPAN TO
GO OUT, SO I PUT TWO.
SO THAT'S ALSO ANOTHER IDEA.
MINE ENDED UP BEING
A 15-TO-1 RATIO.
HELLO.

The caller says HELLO?

Lorraine says HI.
AND WHAT ARE SOME OF THE
PROBLEMS YOU HAD, OR...?

The caller says THE WHEEL WOULDN'T
LINE UP WITH THE GEAR.

Lorraine says OKAY, SO WHAT DID
YOU END UP DOING?

The caller says WELL, WE KIND OF HAD THE
TEACHER HELP US BECAUSE WE
COULDN'T GET IT TOGETHER.

Lorraine says OKAY, AND WHAT SOLUTION...
WHAT DID YOU USE AS A
SOLUTION, OR WHAT DID YOUR
TEACHER SUGGEST?

The caller says SHE... I DON'T KNOW.
SHE TRIED DIFFERENT
TYPES OF GEARS AND STUFF.

Lorraine says OKAY, SO DIFFERENT
ONES TO CONNECT TO WHAT?
TO THE WHEEL?

The caller says TO CONNECT TO THE WHEEL.

Lorraine says OH, OKAY.
SO AS YOU CAN SEE FROM MINE
OVER HERE, A 45 FITS NICELY.
WHICH ONE DID YOU PUT?

The caller says 45.

Lorraine says NOW, WHAT DO YOU THINK'S GOING
TO HAPPEN IF I PUT A 75 HERE?

The caller says IT MIGHT BE TOO BIG.

Lorraine says YEAH, DEFINITELY
IT'LL BE TOO BIG.
IT'LL STICK RIGHT OUT, SO
THAT'S WHY WE'RE LIMITED TO
45 OR 15, OKAY?

The caller says MM-HMM.

Lorraine says GREAT, THANKS.

The caller says OKAY, BYE.

Lorraine says BYE.
OKAY, AND LET'S TRY
SOMEONE FROM USBORNE.

The caller says HELLO?

Lorraine says HI.

The caller says HI.

Lorraine says DID YOU WANT TO SHARE WITH
US SOME OF YOUR SUCCESSES
OR PROBLEMS?

The caller says WE HAD THE SAME PROBLEM.
WE COULDN'T FIND THE RIGHT
HOLE TO PUT THE WHEEL IN.

Lorraine says AND DID YOU FIND A SOLUTION?

The caller says YEAH, WE JUST FOUND IT.

Lorraine says AND WHAT DID YOU
END UP PUTTING?

The caller says WE ENDED UP JUST TRYING A
WHOLE
BUNCH OF DIFFERENT THINGS,
AND WE FINALLY GOT IT.

Lorraine says AND DO YOU KNOW WHAT GEAR
RATIO YOU HAVE AS A GEAR TRAIN?

The caller says YEAH.
ON THE BOTTOM ROW...
THE SECOND ONE IN.
AND WE JUST...
WE TRIED EVERYTHING AND
THEN WE FINALLY GOT IT.

Lorraine says OH, WELL GOOD FOR YOU.

The caller says OH, OUR GEAR RATIO?

Lorraine says YEAH.

The caller says I'M NOT SURE.

Lorraine says OKAY, WELL THAT WOULD BE
SOMETHING YOU COULD POSSIBLY
TRY OUT THEN, AND THEN IT'LL
BE INTERESTING TO SEE.
OKAY, THANKS VERY MUCH.

The caller says OKAY.

Lorraine says OKAY, BYE.
SOMETHING TO KEEP IN MIND AS
WELL IS WHEN YOU'RE TRYING A
GEAR TRAIN, ONE PARTICULAR
GEAR TRAIN, IS TO MAKE SURE
THAT YOU USE YOUR DESIGN LOG,
WHICH IS, IF YOU LOOK AT THE
GRAPHICS CAMERA HERE, THE
DESIGN LOG WHERE YOU ACTUALLY
SHOW YOUR GEAR TRAIN
CONFIGURATION ON --
REMEMBER, THIS IS YOUR VEHICLE
FRAME THERE WITH ALL THE
HOLES, AND YOU PUT THE GEAR
RATIO IN HERE AND YOU TALK
ABOUT IT.
THIS WAY, AT ALL TIMES, YOU
CAN REFER BACK TO IT AND SEE
WHICH ONE WORKED BEST FOR YOU,
AND SO THAT YOU DON'T FORGET
AND GO ALL OVER THROUGH ALL
THOSE STEPS ONCE AGAIN.
IF YOU LOOK AT MY GEAR RATIO,
WHICH IS A 15-TO-1, YOU'LL
SEE HOW QUICKLY IT MOVES AND,
AGAIN, I MAKE SURE I'M USING
THE POSITIVE TO POSITIVE AND
THAT MAKES IT RUN THIS WAY.
WHOOPS, WE'VE LOST IT ON THE
SCREEN HERE, BUT LET'S TRY THIS.
IT'S GOING BACK NOW.
AND IF I TRY IT ONE MORE TIME,
YOU SEE HOW FAST IT GOES.
THAT'S THE PART I LIKE.
SO WHEN YOU'RE TRYING TO DO
THIS IN THE CLASSROOM DURING
THE WEEK, IT'S A GREAT
OPPORTUNITY TO SEE WHAT THE
RATIOS ARE ACTUALLY LIKE.
THAT WAS A 15-TO-1, SO IF
YOU HAVE SOMETHING GREATER
THAN THAT, IT'LL GO THAT MUCH
SLOWER, OR A LOWER GEAR RATIO,
IT'LL GO THAT MUCH FASTER.
OKAY?
AND YOUR HOMEWORK FOR THIS WEEK,
FOR THURSDAY IS AS FOLLOWS:
HERE WE GO.

The homework slate appears on screen. It reads “1- Build gear trains that go from the motor shaft to a wheel axle. 2- Explore different motor mounting positions. 3- Design Log slash Log Folder. 4- Make a list of problems and solutions.”

Lorraine says WHICH IS WHAT YOU'VE DONE,
AND AS YOU CAN TELL,
YOU NEED MORE TIME TO DO SO.
USE THAT, IF POSSIBLE, THIS
WEEK SO THAT AT THE BEGINNING
OF NEXT THURSDAY'S LESSON,
I CAN ANSWER ANY QUESTIONS
THAT YOU MAY HAVE.
SO WHEN YOU DO YOUR GEAR
TRAINS, NUMBER ONE, MOVE
AROUND THE DRIVE GEAR SO THAT
YOUR MOTOR MOVES AROUND AS
WELL, SO THAT YOU COULD SEE
WHAT IT'S LIKE WHEN IT'S
MOUNTED UP ABOVE OR DOWN BELOW
AND SEE WHAT WORKS BEST FOR YOU.
WHICH LOOKS LIKE THIS,
AND YOUR OBSERVATIONS.
THIS IS
SO
IMPORTANT.
IT WILL REALLY HELP YOU
FOR YOUR FINAL PROTOTYPE.
AND YOUR LOG FOLDER, DON'T
FORGET TO PUT ALL THIS
INFORMATION INTO YOUR LOG
FOLDER SO THAT YOU DON'T GET
IT ALL MIXED UP AND SO YOU CAN
REFER TO IT IN THE FUTURE.
AND, FINALLY, MAKE A LIST OF
YOUR PROBLEMS AND SOLUTIONS SO
YOU CAN SHARE THEM WITH US
AT THURSDAY'S LESSON, OKAY?
AND AT THIS POINT, I WILL TAKE
A FEW MORE CALLS, AND FOR THE
REST OF YOU, TO LET YOU KNOW
THAT ON THURSDAY, WE ARE GOING
TO BE TALKING ABOUT
MOTORS AND GEARS.
WE'RE GOING TO BE SHOWING
YOU SOME MANUFACTURING OF
PARTICULAR OBJECTS THAT I'M
SURE YOU'RE FAMILIAR WITH, AND
WE WILL HAVE A GUEST ENGINEER
THAT WILL COME IN AND ANSWER
ANY OF YOUR QUESTIONS AS WELL,
SO YOU COULD START THINKING OF
SOME QUESTIONS TO ASK, AND
I ASK THAT YOU HAVE A GREAT
COUPLE OF DAYS AND IF YOU HAVE
ANY QUESTIONS, BRING THEM
ON THURSDAY.
AND I'LL PUT UP YOUR HOMEWORK
AND I'LL ANSWER SOME OF YOUR
QUESTIONS IN THE
NEXT FEW MINUTES.

The caller says HELLO?

Lorraine says HI, DO YOU HAVE
A QUESTION?

The caller says I HAVE A QUESTION.

Lorraine says UH-HUH.

The caller says DOES IT MATTER WHAT
SIZE THE GEARS YOU USE?

Lorraine says NO, IT DOESN'T.
THE ONLY THING IS YOU WILL
NOTE THAT WITH YOUR VEHICLE,
IF YOU PUT THE LARGEST GEAR,
THE 75 GEAR ON THE WHEEL AXLE,
IT'S TOO LONG.
LIKE, IT'LL TOUCH THE BOTTOM
BEFORE YOUR WHEEL DOES.
OKAY, SO TO KEEP THAT IN MIND.

The caller says OKAY.

Lorraine says OKAY?

The caller says THANKS.

Lorraine says THANKS, BYE.
TRY ONE MORE QUESTION
FROM SAINT CHARLES.
HELLO.
HI.
HELLO?

The caller says HELLO?

Lorraine says HI, IS THIS LINDSAY?

The caller says YEAH.

Lorraine says HI.
YOU HAVE A QUESTION FOR ME?

Lindsay says THE WHEELS, GEARS AND
SPACES ARE HARD TO PUT ON.

Lorraine says THE WHEEL GEARS
ARE HARD TO PUT ON?
YES, I AGREE.
SO ONE...
I FIND WHEN YOU'RE TURNING IT,
LIKE A LITTLE BIT AND PUT A
PRESSURE ON IT, IT'LL GO IN
BETTER, OR YOU'LL NOTICE THAT
YOUR COLLAR, YOUR DRIVE
COLLARS AND YOUR AXLES HAVE A
LITTLE BIT OF AN INDENTATION.
HAVE A LOOK AT THAT AND PLAY
WITH IT AS YOU'RE TURNING
IT IN, OKAY?

Lindsay says OKAY.

Lorraine says AND THAT SHOULD HELP.
PRACTICE MAKES PERFECT,
BECAUSE AT FIRST, I WAS
STRUGGLING QUITE A BIT AND NOW
IT'S, LIKE, NO PROBLEMS AT ALL
AND IT TAKES PRACTICE
THOUGH, OKAY?

Lindsay says OKAY.

Lorraine says GREAT, THANKS.

Lindsay says BYE.

Lorraine says BYE.
AND FROM SOUTHWOOD PARK.

The caller says HELLO?

Lorraine says HI, YOU HAVE A QUESTION?

The caller says YEAH.
DOES IT MATTER WHERE THE
WHEELS GO, NOT IN FRONT BUT
ON THE SIDE, IF IT'S, LIKE,
ON NUMBER TWO OR...?

Lorraine says NO, AS LONG AS YOUR WHEELS
ARE TOUCHING AT THE BOTTOM.
LIKE, AT FIRST, WHAT I ENDED
UP DOING IS PUTTING ONE WHEEL
MORE IN THE CENTRE AND ONE IN
THE FRONT AND IT SEEMED TO WORK.
THERE WAS ANOTHER TIME WHERE
I DID THAT BUT THERE TOO MUCH
PRESSURE IN THE BACK, SO THEN
I WAS DOING A WHEELIE AND IT
WAS QUITE FUNNY, BUT THAT'S
WHERE I WAS LEARNING.
AND IF YOU THINK THAT, BY
PUTTING IT ON THE SECOND ROW,
THAT YOUR WHEELS WILL STILL
TOUCH, GO FOR IT, TRY IT.

The caller says HELLO?

Lorraine says HI.

The caller says WE TRIED IT AND IT JUST...
IT WENT FASTER, SO I
GUESS IT'S GOING TO WORK,
BUT WHEN WE TRIED PUTTING
IT IN THE MIDDLE, IT DIDN'T
GO AS FAST, SO...

Lorraine says IT DIDN'T.
THAT MIGHT BE A GOOD THING
TO TRY AND FIGURE OUT WHY,
AND WE CAN TALK ABOUT
THAT ON THURSDAY.

The caller says OKAY, THANK YOU.

Lorraine says OKAY?
THANKS, BYE.
LET ME TRY ONE MORE CALL
HERE FROM SAINT CHARLES.

The caller says HELLO?

Lorraine says HI, YOU HAVE A QUESTION?

The caller says YEAH.
IF YOU PUT MORE GEARS ON IT,
WOULD IT GO FASTER OR SLOWER?

Lorraine says WELL, THERE AGAIN, IT
DEPENDS ON YOUR GEAR RATIO.
THAT'S WHERE THE GEAR TRAINS,
REMEMBER HOW WE TRIED TO
CALCULATE WHAT IS YOUR RATIO?
IF THE RATIO IS, LIKE, 15-TO-1,
THEN YOU KNOW THAT YOUR MOTOR IS
GOING 15 TIMES BUT YOUR WHEELS
ARE ONLY GOING ONCE, OKAY?
BUT IF IT'S REVERSE, WHERE
THIS ONE'S GOING ONCE, LIKE IF
YOU PUT A BIGGER GEAR HERE
AND A SMALLER, IF THE RATIO'S
SWITCHED AROUND, THEN YOU
KNOW YOU'RE GOING TO GO
THAT MUCH FASTER.
SO YOU GOT TO KNOW
YOUR GEAR RATIO.
YOU HAVE TO FIGURE IT OUT BY
LOOKING AT YOUR GEAR TRAIN.
THAT'S WHY WE LEARNT IT.

The caller says OKAY.

Lorraine says OKAY?
GREAT, THANKS.
AND SOMEONE FROM
USBORNE CENTRE.
HI.

The caller says HI.
I WAS WONDERING IF WE'RE
ALLOWED TO USE EXTRA MATERIALS
ON OUR CAR?

Lorraine says THAT'S ENTIRELY
UP TO YOUR TEACHER.
IF THEY FEEL THERE'S
NO PROBLEMS THERE...
THAT'S ENTIRELY UP TO YOU.
IF NOT, THEN MAYBE YOUR
TEACHER'S GOING TO WANT IT TO
BE CONSISTENT WITH EVERYBODY
ELSE IN THE GROUP.
IF THEY FEEL THAT, YES, YOU
CAN, THEN THAT MEANS EVERYBODY
SHOULD BE AWARE OF THAT.
OKAY?

The caller says OKAY.

Lorraine says SO IT'S UP TO YOU
AND YOUR TEACHER.

The caller says THANKS.

Lorraine says GREAT, OKAY.

The caller says BYE.

Lorraine says FROM SAINT JEAN DE BREBEUF.

The caller says HELLO?

Lorraine says HI.

The caller says I WAS WONDERING, DO WE HAVE TO
HAVE THE GEARS ON THE OUTSIDE,
OR COULD WE PUT THEM
INSIDE THE FRAME?

Lorraine says WELL, THE THING IS, IF YOU
PUT THEM ON THE INSIDE, THEN
YOU'RE GOING TO HAVE TO TAKE
YOUR MOTOR AND DO IT REVERSE.
ENTIRELY UP TO YOU.
TRY IT OUT, SEE IF IT WORKS.

The caller says OKAY.

Lorraine says OKAY, GREAT.

The caller says BYE.

Lorraine says AND SOUTHWOOD PARK
AGAIN, I BELIEVE.
HI.

The caller says HELLO?

Lorraine says HI.
YOU HAVE A QUESTION?

The caller says DOES IT MATTER WHAT GEAR
COMBINATION WE PUT IF WE WANT
THE CAR TO GO FASTER?

Lorraine says WELL, DO YOU REMEMBER WHEN WE
TALKED ABOUT THE GEAR RATIO OF
DIFFERENT TRAINS, GEAR TRAINS,
DO YOU REMEMBER WHAT GEAR
RATIOS ARE BEST FOR SPEED?

The caller says PARDON?

Lorraine says DO YOU REMEMBER WHAT GEAR
RATIOS ARE BEST FOR SPEED?
THINK OF YOUR BIKE.
WELL, A GOOD REFRESHER, IF YOU
TRY THE GEAR RATIO, IF YOU
NOTICE THAT THE RATIO OF THE
DRIVE GEAR IS CLOSE TO THE
WHEEL GEAR, THEN YOU'LL BE
GOING A LOT FASTER, OKAY?
SO YOU DON'T WANT A BIG SPREAD
LIKE 30-TO-1, LET'S SAY,
WHERE THIS IS TURNING
30 AND THIS JUST ONCE.
YOU WANT IT QUITE CLOSE, LIKE
WHERE THIS COULD BE 8-TO-1,
OR VICE VERSA,
1-TO-8.

The caller says OKAY.

Lorraine says OKAY?
AND THE BEST THING THERE
IS TRIAL AND ERROR.
TRY THEM OUT.
SEE WHAT WORKS BEST AND
USUALLY BY VISUALIZING IT
AND TRYING THE DIFFERENT GEAR
TRAINS, THAT'S WHERE YOU SEE
FOR YOURSELVES WHICH ONE WORKS
BEST, WHICH ONE GIVES YOU
SPEED, WHICH ONE GIVES
YOU THE BEST TO GO UPHILL
AND GO SLOWLY.
OKAY?
AND A QUESTION FROM
USBORNE CENTRE.

The caller says HELLO?

Lorraine says HI, YOU HAVE A QUESTION?
DAVID OR ZACH, DO
YOU HAVE A QUESTION?

The caller says NO, NOT REALLY.
SOMEONE PRESSED THE THING.

Lorraine says OKAY, AND HOW IS IT GOING FOR
YOU AS FAR AS YOUR VEHICLE?

The caller says PRETTY GOOD.

Lorraine says GOOD.
OKAY, YOU'RE UNDERSTANDING WHAT
YOU HAVE TO DO FOR THURSDAY?

The caller says YEAH.

Lorraine says OKAY, GREAT.
THANKS.

The caller says YEAH, BYE.

Lorraine says HELLO.

The caller says HI.

Lorraine says HI, YOU HAVE A QUESTION?

The caller says YEAH.
IS THERE A MINIMUM AMOUNT
OF GEARS WE HAVE TO HAVE
ON OUR CAR?

Lorraine says NO, IT'S ENTIRELY WHAT YOU'RE
WANTING TO ACCOMPLISH WITH
YOUR VEHICLE.
NOW, I DID MENTION IF YOU WERE
TO USE ALL THE GEARS, THERE'S
SUCH A THING AS A
RATIO OF 225-TO-1.
DO YOU KNOW WHAT THAT MEANS?

The caller says IT'S PRETTY SLOW.

Lorraine says YOU'RE RIGHT.
THE DRIVE GEAR WITH THE MOTOR
WILL TURN 225 TIMES WHILE THIS
WHEEL TURNS ONCE, SO IT'S VERY
SLOW AND, OBVIOUSLY, YOU CAN
DO IT THE OTHER WAY AROUND.
BUT, NO, IT'S WHATEVER IT IS
YOU'RE WANTING TO ACCOMPLISH
WITH YOUR VEHICLE.

The caller says OKAY, THANKS.

Lorraine says GREAT.

The caller says BYE.

Lorraine says AND LET'S TRY ONE MORE CALL
AND THEN WE'LL WRAP IT UP
FROM THERE.
FROM USBORNE CENTRE.
HELLO?

The caller says HELLO?

Lorraine says HI.

The caller says IS THERE ANY WAY WE COULD
DO, LIKE, FOUR-WHEEL DRIVE?

Lorraine says A FOUR-WHEEL DRIVE?

The caller says YEAH.

Lorraine says AND HOW WOULD YOU
WANT TO DO THAT?

The caller says MAYBE FOR GOING
UP A HILL, LIKE...

Lorraine says THAT'S RIGHT.

The caller says MAKE IT FASTER.

Lorraine says OKAY, AND WHICH WHEELS
SHOULD YOU PUT IT ON,
THE FRONT WHEELS OR THE BACK?

The caller says BOTH.

Lorraine says OKAY.
WELL, YOU CAN ALWAYS TRY THAT
OUT, BUT THE ONLY PROBLEM WILL
BE YOU'LL PROBABLY NEED TO WORK
IT OUT WITH YOUR MOTOR HERE.
THAT'S A GREAT QUESTION.
YOU CAN TRY THAT OUT THIS WEEK
AND MAYBE SHARE WITH US NEXT
WEEK, OR ON THURSDAY HOW
SUCCESSFUL YOU WERE.
WANT TO DO THAT?

The caller says OKAY.

Lorraine says GREAT, THANKS.
OK. BYE.
WELL, THANKS VERY MUCH FOR
ALL YOUR CALLS AND YOUR
GREAT PARTICIPATION.
I HOPE YOU HAVE AS MUCH FUN
AS I DID TRYING TO PUT YOUR
VEHICLE TOGETHER AND SHARE
WITH US ON THURSDAY AT THE
BEGINNING OF THE LESSON IF
YOU HAVE ANY PROBLEMS OR
SUCCESSES, AND LOOK FORWARD
TO HEARING FROM YOU.
BYE-BYE.

The homework slate appears again.

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