The Power of A Prism
Shine a beam of white light on a prism it breaks
it up into RED ORANGE YELLOW GREEN BLUE INDIGO
VIOLET This is called DISPERSION

Spin the colored wheel aroundThe different
colors turn to whiteWhite is a mix of loads of
different colors

Make A Rainbow

1. Place some black paper in a dish full of water
2. Drop some clear nail polish onto the waters
   surface
3. Leave it for a few minutes
4. Gently lift the paper out of the water let it
   dry
5. Hold the paper in some light view your rainbow

EYE MODEL Imagine slicing an eye in 2 It would
look like this oooooooohhhhh U can see the lens
inside the eye This helps u focus

UPSIDE-DOWN

• When you look at something it reflects onto the
  back of your eye
• Only problem is it is upside-down this is called
  INVERSION
• Good thing your brain can flip the image the
  right way up
• This pinhole camera (a black painted cup with
  some greaseproof paper and a tiny hole) can demo
  inversion
• The flame appears upside down on the greaseproof
  screen

MICROSCOPE
Ever wished you could see tiny objects? A
microscope will let u see tiny things You can
check out little creepy crawlys Or even zone in
on your own cheek cell A microscope lens will
enlarges things This is known as magnification
what a magnificent machine

Crookes Radiometer
Place it in sunlight or shine a lamp at
it Wooooh Im dizzy look at the vanes turning
like Crazy The light energy gets changed into
kinetic energy Kinetic energy gets things
moving grooving.

SONIA - SOUND

Tired of wasting money on mobile credit ? Make a
string telephone call your mates for free.
Heres HowPierce a hole in the base of 2
plastic cupsThread a long piece of string
through the holesTie a granny knot on the inside
of the cupsPull the string tight and get
dialingYour voice will travel in a
along the string 2 your mates earYou will
see the string vibrate cause sound travels in a
Sing your own ring-tone go on give it a go..

• PLACE 2 OPEN UMBRELLAS FACING EACHOTHER 6 METERS
  APART
• PUT A TICKING CLOCK NEAR THE MIDDLE OF THE STICK
  HANDLE OF 1 UMBRELLA
• THE CLOCK WILL BE HEARD AT THE SAME POSITION ON
  THE OTHER UMBRELLA
• IT GETS REFLECTED AND BOUNCES ACROSS

HEARING - Fun Facts

• Small children animals can hear high pitched
  sounds better than adults.
• People who are blind normally have a sharper
  sense of hearing.
• Your ears never stop growing as you get older.
• Ultrasound scans let us see unborn babies in the
  womb.

DIG - ICT
15
COMPUTERS SCIENCE

• Scientists often give presentations to audiences
  using computers to show tables, charts, pictures
  graphs.
• We can store scientific data results on
  computers to keep them safe.
• Computers help us carry out statistical analysis
  on experiments.
• Computers help Scientists research information on
  topics via the internet.
• Scientist all over the world can share theories,
  results ideas by communicating through
  computers

Invisible Ink

• Heres a good experiment to do around pancake
  Tuesday
• Dip a cotton bud into some lemon juice
• Write a secret message on some paper let it dry
• Ur message will have disappeared like Magic
• Blast it dry with a hairdryer it reappears
• The acidic lemon weakens the paper heat makes
  it turn brown

17
You can make soap from 125ml oil , 100ml water
20g sodium hydroxidePour the oil water into a
beaker and stir itAdd the sodium hydroxide
keep stirringIt can be jazzed up by adding some
smelly oils or perfumeUMMM smells great but I
wouldnt use it on ur bodySodium hydroxide is
corrosive could burn your skin oouuccchhh
Lets Get Soapy
To This WOW!

COKE A PENNY
Take a can of Coke a dirty penny Drop in the
dirty penny.....fizzzzzzz Days later BLING its
sparkling Citric Phosphoric acid in Coke
removes the stains
19
HARD WATER

• Hard water contains more minerals doesnt make
  suds easily
• Test different types of water to see if they are
  hard
• Add soap flakes to different water samples
• The ones that dont make suds are hard as it
  traveled over rocks like limestone sucked up
  some minerals like calcium

Basic Battery

• Want to make your own battery?
• Its easy to make a
• Place 5 cent 10 cent coins in a pile (alternate
  them)
• Put some tissue soaked in salty water between the
  different coins
• Hook up some wire a voltmeter your powered up
• Build it higher by using more coins from the back
  of your couch!

Voltaic pile
22
Lemon Clock

• You need 2 Lemons, 2 pennies, 2 paper clips,3
  pieces of copper wire, a scissors, a knife, a
  Voltmeter, a battery-operated digital clock, a
  pencil paper
• Clip a paperclip 2 a wire hook a penny to a
  second wire.
• Attach another penny to 1 end of the third wire
  a paperclip to the other end
• Squeeze 2 lemons make 2 small cuts in the skins
  of both an inch apart.
• Put the paper clip that is attached to the wire
  the penny into 1 of the cuts down into the juicy
  part of the lemon.
• Stick the penny in a hole in the other lemon.
• Put the other paper clip into the second hole of
  the lemon with the penny.
• Then put the last penny into the last open hole.
• Connect the free ends of the wires to the
  terminals of the digital clock.
• The lemons make enough electricity 2 turn on the
  clock.
• Chemical reactions between the steel paper clip
  the lemon juice between the copper penny
  the lemon juice push electrons through the wires.
  The metals are different so electrons get pushed
  harder in 1 direction. Electrons flow around in a
  circle and come back 2 the lemon battery. This is
  called an electric current.

23
MAGNETIC

• Want to plot a magnetic field ?
• Put a magnet under some paper
• Sprinkle iron fillings on top of the paper
• The iron will map out a magnetic field
• North, East, South or West u know The Resistors r
  the Best!!!!

Build this shaky hand game its a simple
circuitmade from a buzzer, a battery, wire,
insulated wire, a shoe box sticky tape.Try
moving the looped wire along the bendy wireIf
the two wires touchyour not that steady and the
bulb lights up TRY AGAIN
