1. Blizzards
By Sophie

2. What are Blizzards?
• Blizzards start when polar and warm air meet, the polar pushes the warm air up
and it stays in the atmosphere part where water vapor forms clouds(source 4)
• They are big winds at atleast 35 mph and have snow pouring down(source 4)
• They can lock you in our house because of snow in front of your house
door(source 3)
• They usually occur often in the North(source 4)
• They can use erosion which can be hard to tell if snow is coming from the ground
or sky(source 4)
• They can also kill people by their mighty force and lock us in houses(source 4)
• In some blizzards ,winds can sound like trains(source 3)
• They can knock down trees, power lines, and small houses(source 2)
• They can leave lots of inches of snow( source 1)
• They happen usually in a pattern in winter(the season of it)(source 1)
• Blizzards keep progressing when they start then they die down(source 1)

3. The affects
• Blizzards affect humans by killing them and
bringing down their houses
• Blizzards also affect animals by either killing or
locking them in holes
• Blizzards affect earth by creating erosion and
washing away some materials(source
• Blizzards can also affect earth by creating a
avalanche(source

4. In the future
• In the future scientists think blizzards will hit
the north, more specifically the northwest.
(Washington, Idaho, Oregon, Montana)
(source 2)
• they think this because that is where blizzards
occur most(source 2)

5. What are some types of blizzards?
• There are ground blizzards, whiteouts, regular
blizzards, and different categorized blizzards
that are categorized by the numbers 1,2,3,and
4 ( Source 2)
• The numbers say if they are major, minor, and
in the middle blizards(source 2)
• A ground blizzard has no precipatation and is
when snow and ice is blown from the
ground(source 2)

6. What is some Blizzards that are
magor?
• There was the 1972 Iran blizzard that was one
of the deadliest in history, it caused about
4000 deaths(source 4)
• Once in NY there was a blizzard suddenly on a
warm day and by the end of it about 400
people had died(source 4)

7. How do Scientists Predict them?
• One way they predict them is the when they
most happen, in the winter(the blizzard
season)(source 4)
• They also can predict where the winds will go
like when they travel in the west winds they
head east(source 4)
• They can also predict them by their devices
that have warnings(source 4)

9. Hypothesis
If I mix hot and cold air then I think the air will just stay in the
middle of the two jars because my research said that thyat hot
air rises and cold air sinks so if they are both in the same space
they will go in the middle.
If I mix hot and hot air then I think the hot air will rise and
stay at the top because my research shows that hot air rises and
since they are both hot air they will rise.
If I mix cold and cold air together then I think that the air will
sink because my research shows that cold air sinks and hot rises.

10. Materials
• 2 quart sized jars
• some matches
• A camera
• Ice pack
• Hot water in pan

11. Experiment variables
• Controlled- how much smoke
Independent-changing warm and cold air
• Dependent-the air

12. Experiment Procedure
First I will gather materials
Second I will put smoke in one jar
Third I will quickly stack the other jar on top of it
Fourth I will put the pan full of hot water under the low jar
Fifth I will put a ice pack on top of the other jar
I will take pictures throughout the experiment
I will then repeat these steps and do them with only a hot water of pan and no ice
then repeat with only ice

13. Experiment results
1- What happens when cold and hot air mix?
Trial1- the airs swirled because the hot pushes up and the cold pushes down so they
go in the middle and swirl
Trial2- air swirls
2-What happens when warm and warm air mix?
Trial1- they go to the top because hot air push up
Trial2- they went to top
3- What happens when cold and cold air mixes?
Trial1- went to bottom because they push each other down
Trial2- went to bottom

14. Conclusion
• My hypothesis on hot and cold air was right and wrong, it was
right that the air would stay in the middle but wrong that the air
would just stay it actually swirled.
• My hypothesis was right on hot and hot air the air did go to the
top and stay.
• My hypothesis was right for cold and cold air the air did stay in
the bottom.
If I were able to change something in the experiment I would
change the way the pictures looked, it is hard to see what it was
a picture about. I would also try harder to put an equal amount
of smoke in both jars.
I think the experiment went well I did what I wanted to
accomplish.

15. Graph of experiment
This is a graph of how much each
questions results swirled. 1= warm and cold
air together. 2=warm and warm air.3= cold
and cold together
