>> IT’S 9, 27 76 DEGREES. WE’LL BE RIGHT BACK. WELCOME BACK. IT’S 9.31.
WE WERE SCHEDULED TO HAVE
SCIENCE WITH SARAH LIVE
YESTERDAY. BUT THE THING ABOUT
LIVE TV, IF THINGS DON’T ALWAYS
GO AS PLANNED, REALLY DOESN’T.
BUT SARAH MCGREW HAD SOME
TECHNICAL DIFFICULTIES, BUT
THEY STILL DID THE EXPERIMENT
WITH THE STUDENTS OUT AT ELM
CREEK ELEMENTARY SCHOOL ON THE
CITY’S SOUTHWEST SIDE CLASS IS
LEARNING ABOUT CIRCUIT. SO
SARAH FOUND AN EXPERIMENT TO GO
ALONG WITH THAT. TAKE A LOOK.
>> DOES EVERYBODY HAVE THE
BATTERY? IS THAT AND THEN NEXT
UP, WE NEED TO GET BETTER.
WE NEED SOME ALUMINUM OKAY.
>> WHEN SHE HER
♪
>> SO TAKE THIS BALL. LOOK AT
IT. UPSIDE DOWN.
YOU SEE THE LONGER PIECE, THE
LONGER PIECE IS THE POSITIVE
WIRE.
>> THE SHORTER PIECE IS THE
NEGATIVE WIRE. OKAY. TAKE YOUR
BATTERY.
>> IN YOUR BATTERY.
>> THE SMOOTH SIDE IS THE
POSITIVE SIDE.
AND THE TEXT READ SIDE IS THE
NEGATIVE SIDE. SO WE’RE LONG
SIDE BE ON THE SMOOTH SITE.
THAT WILL MAKE IT AND THEN IF
YOU FLIP IT AROUND, IT WILL
NOT LIGHT UP BECAUSE THAT’S THE
THE NEGATIVE SIDE IS ON THE
POSITIVE SIDE. SO THAT’S HOW
THE BATTERY IS GOING. IT IS
GOING TO LIGHT UP YOUR LIFE
WILL BE OKAY. SO. I’M GOING TO
SHOW DAVID FOR THE CAMERA.
I’M GONNA SHOW DAVID HOW TO
MAKE THE INDEX CARD.
FLASHLIGHT.
AND THEN WE’RE GOING TO DO IT
TOGETHER. OKAY, GUYS. ALL
RIGHT.
SO WE HAVE A MATERIALS.
>> AND YOU HAVE YOUR TAPE,
DAVID, YOU HAVE A TAPE.
>> SO IN ORDER TO MAKE AN INDEX
CARD FLASHLIGHT, YOU NEED THESE
MATERIALS. YOU NEED AN LED
LIGHT BULB. YOU GET A PACK OF
100 FOR THESE THAT AMAZON FOR 7
BUCKS. YOU NEED A SMALL 3 VOTE
BUTTON BATTERY, AN INDEX CARD,
ALUMINUM FOIL AND SOME TATE.
NOW MY SECRET IS I LIKE TO USE
THESE FILE FOLDER LABELS
BECAUSE THEY’RE A LITTLE BIT
STRONGER AND THEY’RE EASIER TO
BREAK UP TO A ROLL OF TAPE.
SO, DAVID, HERE’S WHAT YOU’RE
GOING TO DO. FIRST THING I WANT
YOU TO DO IS TO FIND THE
POSITIVE SIDE OF THE LIGHT
BULB, WHICH IS THE LONGER END.
NOW YOU’RE GOING TO YES,
EXACTLY. THAT’S THE POSITIVE
SIDE TO PUT THAT UP TO THE
POSITIVE SIDE OF THE BATTERY,
WHICH IS THE SMOOTH SIDE.
AWESOME. SO WE KNOW THE LIFE OF
WORKS, OK? SO THE FIRST THING
YOU’RE GOING TO DO IS WITH THIS
CARD, YOU’RE GOING TO TAPE YOUR
LIGHT BULB TO THE TOP HERE AND
TAKE NOTE OF WHICH SIDE IS
POSITIVE SIDE, WHICH SIDE IS
THE NEGATIVE SIDE WHICH HAS A
SHORT SAID, WELL, YOU CAN MAKE
A MARK HERE. SO ON THE ON THE
SIDE OF THE CAR THAT YOU’RE
GOING TO POSITIVE, PUT A PLUS.
AND ON THE SIDE OF THE CAR THAT
RATE INTO NEGATIVE PUT A
NEGATIVE. SO SHORT SIDE IS THE
IS THE NEGATIVE SIDE TO YEAH.
>> YOU WANT TO MARK THIS
BECAUSE ONCE THERE’S TAPE ON
IT, IT’S A LITTLE BIT DIFFICULT
TO KNOW EXACTLY WHICH SIDE IS
WHICH.
THE STATE? YEAH. NEW PIECE OF
TAPE AND MAKE SURE YOU LEAVE
PLENTY OF ROOM AT THE BOTTOM.
NO. SO YOU NEED TO MAKE IT
SKINNY YEAR. YEAH. SO THAT WE
CAN LEAVE PLENTY OF ROOM FOR
THE ALUMINUM FOIL TO HAVE
CONTACT. THE POSITIVE SIDE.
YEAH, THERE YOU GO AND DO THE
SAME ON THE NEGATIVE. ALL
RIGHT. KIDS, I WANT YOU GUYS TO
DO THE SAME THING THERE THAT WE
JUST DEAD. SO NOW WHAT YOU’RE
GOING TO DO IS YOU’RE GOING TO
FOLD A PIECE OF FOIL LONG WAYS.
AND THEN GO AHEAD AND TEAR IT.
SO THAT WAY. IT’S JUST A SKINNY
LONG PIECE OF FOIL. THAT’S
GOOD.
JUST A SKINNY LONG PIECE OF
FOIL. OKAY. NOW YOU’RE GOING TO
MAKE SURE ON THE POSITIVE SIDE
TO TAKE THAT ONTO THE EXPOSED
WIRE. EXACTLY LIKE THAT.
WILL HAS BEEN. AND HERE’S THE
KEY. NOW. YOU’RE GOING TO TAKE
THE POSITIVE SIDE OF THE
BATTERY DOWN ONTO THE ALUMINUM
FOIL.
THE OTHER WAY LIKE THIS ON TOP
OF LIKE THAT, PERFECT, YOU’RE
GOING TO WANT TO TAPE IT, BUT
YOU’RE GOING TO WANT TO LEAVE
ROOM ON THE BATTERY THAT NO
LIKE THIS. THE ROOM ON THE
BATTERY. I DO IT LIKE YOU KNOW
WHAT I’M SAYING IN
THE CENTER. THE BATTERIES THAT
STRETCHED. HAHA, YOU’RE DOING
GREAT. DAVID.
>> OKAY. AND NOW GO AHEAD AND
TEAR THIS YEAR. THE BOIL.
YEAH. CLOSE THE BOTTOM YET.
FLIP IT OVER. ATTACH THIS TO
THIS SIDE OF YOUR FOILS, NOT
LONG ENOUGH. SO LET’S GET A
LONGER MEANS OF OIL.
IT’S GOT TO GO ALL THE WAY TO
THE OTHER SIDE.
>> WELL, THIS IS ALONG
EXPERIMENT. I KNOW THAT’LL
AND NOW WHEN YOU ATTACH THIS TO
THE BATTERY AND SHOULD TURN
HAHA AND YOU’LL NOTICE THAT IT
IT TAKES A LITTLE BIT OF.
>> FIDGETING TO GET PERFECT.
BUT THEN IT DOES BECAUSE IT
CONNECTS THERE TO THE NEGATIVE
SIDE. SO THAT’S HOW CIRCUIT
WORKS. GOOD JOB, GUYS.
>> AND WHEN YOU TAKE WHEN YOU
TAKE THEM BACK TO THE LIGHT,
THE LINE THERE, YOU WANT TO
MAKE SURE A LOT OF THE WIRE
IS EXPOSED. OKAY. SO WHAT I
WOULD ACTUALLY IS I WOULD MOVE
THIS UP A LITTLE BIT SO THAT
WAY. THE LOT MORE OF THE WIRE
COMES IN CONTACT WITH THE
ALUMINUM SO YOU TAKE THE OTHER
SIDE DOWN TO SO YOU HAVE A FULL
THE FULL ALL RIGHT.
>> WE CAN’T DO ANYTHING ABOUT
THIS THING
SO FAR
>> I THINK IT’S GOING TO BE
COOL AND IT LOOKS LIKE.
>> REALLY CLICKED TO DO.
SO LIKE IT’S KIND OF LIKE IF
YOU’RE DOING A PROJECT AT THE
STATE AND THAT’S WHAT THIS IS
KIND OF INTERESTED IN IT.
YEAH, THE DETAILS
HERE’S A DOUBLE DOUBLE RIGHT
HERE. THEY FEEL ABOUT IT.
>> HEY, IT’S JUST HARDER,
COMPLICATED. AND I DON’T SAY
THAT. DON’T THINK IT IS.
INTRICATE. YEAH. SURE WHAT
MAJOR LIFE. ALL TOO ONE.

FOR MORE SCIENCE WITH SARAH
EXPERIMENT SEEKING GO TO
KSAT.COM.
>> GOOD JOB, GUYS.
>> YOU STRUGGLED A LITTLE BIT
THERE. WELL, YOU SLIGHT AND
SOMETIMES IT WORKED SOMETIMES
GOT LIKE A LIVE SHOT. YOU KNOW?
YEAH, HE’S AN EXPERIMENT.
I LOVE TODAY. IT DIDN’T WORK.
AND SO SOME OF THE KIDS COULD
GET IT RIGHT OFF THE BAT.
SOME HAD TO WORK AT IT CHANGED
THE FOIL, GET LESS. THEY GET
MORE THINK FLIP IT AROUND.
DO THIS, DO THAT AND ALL KINDS
OF STUFF THAT SCIENCE. THAT’S I
MEAN, I LOVE HOW WHEN YOU ASKED
ONE OF THE LITTLE GIRLS LIKE
IS IT INTO CATCHES LIKE I MEAN,
KIND OF WHERE YOU’RE LIKE?
