Time yourself: How quickly
can you find the two hockey
players below that are exactly
the same? Now have a parent
try. Who was fastest?

People around the world are now
following the excitement of the
2018 Winter Olympic Games
in PyeongChang, South Korea.
At right is the flag of South
Korea. Unscramble the words
to find out what each symbol
on the flag represents.
This symbol is known as yin and yang. Yin and yang mean
literally the “dark side” and the “sunny side” of a hill. The symbol
means that everything in the world has its opposite.

What time is it in PyeongChang?

Benjamin lives in San Francisco, California,
which is in the Pacific Time Zone. His pen
pal Tessa, lives in Atlanta, Georgia, which is
in the Eastern Time Zone. Their pal Charlotte
lives in Denver, Colorado, which is in the
Mountain Time Zone. Charlotte’s cousin
Megan lives in New Orleans, Louisiana,

Now have a
friend try. Who
found the most?
To get more spins, a skater needs to twirl as fast as
possible. To increase their twirling speed, a skater
starts a twirl with arms out wide. Keeping the
body straight and bringing the arms in close to
the body causes a skater to twirl faster. This is a
scientific principle called the conservation
of angular momentum.
In order to twirl well, a skater needs velocity, or
speed. A skater uses his or her feet to push off the ice
to accelerate. Once the right velocity is reached the
skater will jump and twirl. The more velocity a skater
gets for the jump, the higher he or she will go.
Connect the dots to find the machine
that cleans the ice.
