Teacher Aldo stands in the lab.

Teacher Aldo is in his thirties, with short curly black hair and a shadow of a goatee. He wears glasses and a blue Homework Zone T-shirt.

He says HI I'M
TEACHER ALDO AND
WELCOME TO THE
HOMEWORK ZONE.
TODAY I'VE
GOT AN EXPERIMENT
TO SHOW HOW PLANTS
DRINK WATER;
YOU CAN DO THIS
EXPERIMENT AT HOME.
HOPEFULLY AN ADULT
WILL HELP YOU.
WHAT YOU'RE
GONNA NEED IS A GLASS,
A LITTLE BIT
OF WATER,
SOME FOOD
COLOURING AND A
FLOWER -
CARNATION FLOWERS
WORK BEST.
WHAT I'D LIKE
YOU TO DO IS TAKE
THE EMPTY GLASS
AND ADD SOME
WATER TO IT
AND REACH OVER,
TAKE YOUR CARNATION
FLOWERS AND PUT
THEM IN AND
THEN ADD ABOUT TWO
OR THREE DROPS OF
FOOD COLOURING.
THIS IS RED
FOOD COLOURING;
OVER A PERIOD OF
24 HOURS ONCE
THE PLANT IS
INSIDE THE WATER
WHAT HAPPENS IS THE
WATER BEGINS TO
BE DRANK
UP BY THE PLANT.
IF YOU TAKE A
LOOK, HERE'S
AN EXAMPLE OF
BLUE AND RED FOOD
COLOURING AND THE
CARNATION
FLOWERS
ACTUALLY TOOK THE
WATER UP THROUGH A
COMPLEX SERIES
OF VESSELS CALLED
XYLEM VESSELS AND
IT CHANGED
THE COLOUR OF THE
PLANT FROM BLUE
TO RED.
IF YOU WANT
TO DO SOMETHING
REALLY NEAT TAKE
ANOTHER
CARNATION
FLOWER AND SPLIT
ITS STEM DOWN
THE MIDDLE.
PUT ONE HALF
INTO THE RED
FOOD COLOURING,
THE OTHER INTO BLUE
FOOD COLOURING AND
THEN WATCH
WHAT HAPPENS
AFTER 24 HOURS.
YOU'LL NOTICE THAT
THE FLOWER
BECOMES HALF
BLUE AND HALF RED.
I'M TEACHER ALDO
AND THAT'S AN
EXPERIMENT YOU
CAN TRY AT HOME.
