TEMPERATURE IT WILL FEEL LIKE 100 OUT THERE WITH SOUTHEASTERLY WINDS 10 TO 15
MILES PER HOUR. GUYS.
>> THANK YOU JUSTIN
WILL SCHOOL MAY BE OUT FOR MOST
KIDS THAT DOESN’T MEAN THE
LEARNING HAS TO STOP THERE’S
ANYTHING WE’VE LEARNED FROM
KAITI BLAKE. SO LEARNING
DOESN’T HAVE TO BE BORING
THAT’S RIGHT. SHE JOINS US NOW
WITH ANOTHER SCIENCE EXPERIMENT
THAT YOU CAN DO AT HOME,
ESPECIALLY NOW THAT THE KIDS
ARE PROBABLY LOOKING FOR THINGS
TO DO AROUND THE HOUSE RIGHT
KATIE YES, WHAT DO YOU HAVE FOR
US TODAY YES, AND EVEN BEFORE
WE GET STARTED WITH TODAY’S IF
YOU TRY THIS ONE AT HOME YOU
LIKE IT THE KIDS ENJOY IT WE’VE
GOT OUR WHOLE LIBRARY OF ALL
THE EXPERIMENTS WE’VE DONE AT
KSAT DOT COM.
>> THE KIDS PAGE THERE WE’VE
GOT OUR OWN KATIE SCIENCE WEB
PAGE SO PLENTY OF STUFF TO KEEP
YOU BUSY ALL SUMMER WALK SO THE
INSPIRATION FOR THIS STATEMENT
WAS THAT YESTERDAY WAS WORLD
OCEANS DAY REALLY AS YESTERDAY
NOT TODAY ON THE BREAK.
BECAUSE I WAS HERE BECAUSE YOU
ARE AT THE OCEAN OCEANS CAN FAR
GULF OF MEXICO. SO FAR AWAY SO
WHAT DO YOU THINK OF WHEN YOU
THINK OF THE OCEAN.
WHAT KIND OF WATER
SALT WATER, SALT WATER, YES, SO
BEFORE WE BEGIN A COUPLE OF
QUICK QUESTIONS FOR DAVID
I WAS
DAVID OF THE EARTH’S SURFACE IS
COVERED BY OUR OCEANS MOST.
AGAIN MOST OF THE ARRESTS ARE
ALWAYS GET THAT AT LEAST 70% OF
OK I WANT TO THAT’S
OUR EMOTIONS. THE
SOFT WATER. IN OUR OCEANS
HOW MUCH SALT ROUGHLY IS IN
ONE LEADER OF OCEAN WATER.
A LITTLE
A LITTLE 35 GRAMS WHICH COMES OUT TO 0, 8, POUNDS SO REALLY
NOT MUCH SO MUCH. BUT THAT
WATER IS REALLY SALTY
ISN’T SO THAT WAS MY
INSPIRATION FOR TODAY’S
ACTIVITY WE’RE GOING TO
TEST THE DIFFERENT DENSITY OF
DIFFERENT TYPES OF WATER,
INCLUDING SALT WATER. SO HERE’S
WHAT YOU NEED REALLY QUICKLY
YOU ARE GOING TO NEED SOME
WATER 4 CUPS FOR EGGS.
SOME SALT SUGAR AND BAKING SODA
I GUARANTEE OF GOT A LOT OF
THIS AT HOME IN YOUR PANTRY AND
IN YOUR FRIDGE, SO WHAT WE’RE
GOING TO DO HERE IS WE’RE GOING
TO USE OUR EGGS TO TEST THE
DENSITY OF THESE DIFFERENT
TYPES OF WATER, SO WE’VE GOT
OUR CONTROL GROUP HERE
WHICH IS WHAT WOULD WHAT WE’RE
LEAVING UNCHANGED, PLAIN WATER,
WE’VE GOT WATER WITH SOME
BAKING SODA
IN ITS WATER THAT NEEDS SUGAR
ADDED TO IT DAVID I’M GONNA LET
YOU DO
IN HERE. 2 TABLESPOON.
>> BUT I THINK YOU CAN BE
PRETTY GENEROUS AND THEN WE’VE
GOT OUR WATER WITH SALT I’VE
ALREADY ADDED THE SALT.
>> AND THE BAKING SODA SO GO
AHEAD AND MAKE SET
UP DAVID I GIVE THIS ANOTHER
STIR HERE AND SO BASICALLY
WE’RE GOING TO DROP OUR EGGS
AND THESE DIFFERENT TYPES OF
WATER TO SEE
WHAT HAPPENS IS A PICTURE TO
THE EXITS FACTS.
BUT A BIG EVENT AS TO WHEN THE
CATCHING ONE OF THE MATH.
WATCHING
SO OKAY WE’RE GOING TO SEE WHAT
HAPPENS WHEN WE DROP OR EGGS
AND SO LET’S START WITH A PLAIN
WATER DAVID WHAT DO YOU THINK’S
GOING TO HAPPEN THESE BOILED
EGGS ARE JUST REAL AND THEY’RE
JUST.
>> WHAT I THINK COULD HAVE WHEN
YOU HAVE BEEN WATCHING THIS
THING. OKAY, IT’S A GOOD EGG
SHOULD SINK.
>> THE PPP AND IT SAID
>> THAT ONE RIGHT THERE IT IS
OK, LET’S SHOW YOUR SUGAR WATER
DAVID IT’S GOING TO SINK.
>> AFTER THAT I DON’T SUGAR
SINK.
>> YES,
THEY SAY.
>> HOME STUDY THERE AT THE NOW
LET’S TRY SALT AND BAKING SODA
WILL TRY BAKING SODA FIRST.
NOT YOU’RE NOT DOING ANYTHING YOU’RE NOT ASSISTING AT ALL I REQUIRES MAXIMUM LANE, WHAT
HAPPENS WITH OUR.
SO FAR EGG IT SO HERE’S WHAT I
DIDN’T THINK THROUGH IT’S HARD
TO SEE THE EGG AND THESE SO
IT’S THERE
IT’S IT IT’S IN THE MIDDLE IS A
KIND OF SUSPENDED. YEAH, IT’S
KIND OF IN THE HEAD.
IT’S KIND OF IN THE MIDDLE GOOD
POLICIES, A TOUCH HARD TO SEE
THIS YES RIGHT LET’S HEAR
HANGING OUT IN THE MIDDLE WHEN
IT SHOULD PUT THE LITTLE PINK A
LOGO ON THE SIDE THERE YOU KNOW
WE CAN SHOULD FLOAT RIGHT.
>> SO I KNOW OUR BAKING SODA THE WATER’S A LITTLE MONEY AND IT’S HARD TO SEE.
BUT.
>> THEY THE EGG WILL ALWAYS SEE
INC UNLESS IT’S IN THE BAKING
SODA OR THE SALT AND WHY DO YOU
THINK THAT IS.
>> BECAUSE SALT IS BUOYANT TO
THE EGG.
>> IT’S MORE IT THAT’S YEAH
IT’S MORE DENSE, YES, SALT
WATER IS MORE DENSE BASICALLY
IT’S HEAVIER.
>> THEN IT EXITS JUST AN OK
COME ON SO IT CHANGES HOW THE
BUOYANCY OF THE EGG. SO THAT’S
WHY THE EGG.
>> ASSAULT HAS BEEN THE SITE
WATER AND WHY WHEN YOU GO
SWIMMING IN SALT WATER. IT’S
NOT IT’S. YOU DON’T SINK LIKE
YOU DO IN A POOL.
>> BECAUSE YOU YOUR LITTLE BOY
IN THE SALT WATER. WATCH OUT
FOR THOSE RIP CURRENTS TO ON
THEM. IF YOU LIKE CRACK IT.
HE
I DON’T KNOW IF IT CHANGES
ANYTHING, YEAH, THE KIDS ANY
IDEA IS WHAT HAPPENS.
>> YOU HAVE
>> OUR LITTLE ENDED YO CAN SOLAR FULL, SO A FUN EXPERIMENT TO TEACH THE KIDDO’S ALL ABOUT
DENSITY AND
WHAT THAT WILL DO TO OBJECTS
PLACED IN A LITTLE CRACK A FEW
EGGS SUMMER. GO AHEAD DAVID I DON’T THINK WE’RE QUITE TO THE POINT WHERE IT’S SO HOT THAT
WE’RE FRYING EGGS OUTSIDE
