3. Sir Isaac Newton was one
of the greatest scientists
and mathematicians that
ever lived.
He was born in England on
December 25, 1643. He
lived for 85 years and
completely changed the
course of scientific
history.
4. It is said that when Sir
Newton was out in his
garden, an apple fell on his
head.
This inspired him to
explain the movement of
objects using certain
‘rules’.
We call these the ‘Laws of
Motion’
5. Law of Inertia
‘An object in motion continues in motion with the
same speed and in the same direction unless acted
upon by an unbalanced force’.
6. Second Law of Motion
Acceleration is produced when a force acts on a mass.
Everyone knows this Second Law. Everyone knows that
heavier objects require more force to move the same
distance as lighter objects.
7. Third Law of Motion
For every action there is an equal and opposite re-
action.
The rocket's action is to push down on the ground with
the force of its powerful engines, and the reaction is
that the ground pushes the rocket upwards with an equal
force.

9. Animal Facts
• Cats conserve energy by sleeping for an
average of 13 to 14 hours a day.
• Cats have powerful night vision, allowing
them to see at light levels six times
lower than what a human needs in order
to see.
• Elephants are the largest land-living
mammal in the world.
• Elephants can swim – they use their
trunk to breathe like a snorkel in deep
water.
• Giraffes are ruminants. This means that
they have more than one stomach. In
fact, giraffes have four stomachs!!
• The horn of a rhinoceros is made from
compacted hair rather than bone or
another substance.
12. This is a picture of ‘Aurora Borealis’, also called ‘The
Northern Lights’. Isn’t it beautiful?!
Molten iron swirls deep within the Earth, which creates a
magnetic field around the planet. If you can, imagine a giant
bar magnet inside the Earth. The ends of this magnet are
where the magnetic north and south (or positive and
negative) poles would be. These magnetic poles are close to
the geographic North and South poles.
When solar winds bombard the Earth with ions, these
charged particles move along the magnetic field lines
toward the magnetic poles. When these particles strike our
atmosphere, they erupt in spectacular displays of light,
what we call the auroras.

We can move the soccer ball because it is lighter

Another legend describes the lights as flaming torches carried by travelers to the afterlife.
