Problem Question
Can I predict the weather
based on the weather
temperatures recently?
Hypothesis
Based on the weather
temperatures recently I can
predict the weather for next
week.
PURPOSE
The purpose of the experiment was to find how
temperature, air pressure, humidity, wind
speed, and wind direction affects weather. Also
to prove that by observing weather patterns it
is possible to predict the weather.
Weather Terms
 CLOUDS
Are masses of water
droplets or ice
crystals that hang in
the troposphere over
the earth.
 Air Mass
Is a large body of air
that has a certain
temperature and
amount of moisture.
 Air Pressure
The measure of the
weight of air
pressing down on a
given area of
Earth’s surface.
 Wind Speed
The measure of how
fast the wind is
blowing.
MATERIALS
• 1 liter soda bottle
• Food coloring (blue, green, or red works best)
• Straw (preferably glass tubing that fits in the
rubber stopper)
• Marker

Fill 1-liter bottle to the top with cold tap water. Add
eight drops of food coloring.
Roll some modeling clay into a small ball about 25mm in
diameter. Then roll it out so that it forms a cylinder
about the length and diameter of a pencil. Flattens the
pencil shape clay into a thick ribbon. (A rubber stopper
that fits snugly into the bottle is preferable). Wrap the
clay ribbon around the mid point of a straw.
Place the straw into the bottle and use the clay to seal off
the bottle.
Press the clay plug into the neck of the bottle far enough
to force the water level up into the straw so that it can be
seen.
Mark the initial water level on the straw. As the
temperature goes up, the water will expand and rise the
water level above this point; as temperature goes down
the water will contract and lower the water level below
the initial level.
Analyze Questions
What data does you’re your instrument provide?
My instrument reads the temperature.
How does your instrument work?
When the temperature goes up the water will expand and rise
the water level. When the temperature goes down the water
will contract and lower the water level.

The Debate Between

Debate Between
Winter &
Which One Is Better ?
Which One
Is &Better
Winter
Summer ?
Summer
Most people love summer because of the
warm days and the refreshing taste of the
ice cream coming right from the ice cream
truck. But there is more to summer than
that. You can open the windows and get
fresh air in your house without freezing to
death. You can play games outside. You can
swim at a pool, a river, a lake, or the ocean.
You can take a relaxing drive around the
countryside without having to put on big
puffy coats or snow boots or worry about
dying in a blizzard if you get car troubles.
You can wear lightweight, comfortable
clothing. You can spend a lazy afternoon
watching a football game. You can go
surfing or swimming. You can skateboard.
You can go to school for summer session if
you want, or you can work.
Winter
Most people hate winter
because of getting hit with
freezing wind in the face or
walking outside and getting your
socks wet while trying to jump
over a puddle.
But there is a bright side.
Looking at fresh snow is always
nice. You can bundle up as much
as you need to stay warm.
People usually reads more
during winter. Indoor hobbies get
some time and attention. It’s
much easier to get warmer than
cool down.
Cold Weather Highlights
You can sleep better in colder
weather. Also there is less bugs
flying around than in the summer.
animals get a chance to
hibernate.
And there are special holidays
in the winter like Christmas,
thanksgiving and new years.

Summary
• I don’t really think that one is better because each
of them have a purpose. But if I had to choose, it
would be Summer.
