We
filled a bottle three quarters full of water, added some drops of dish washing
liquid, and some glitter. We spun the bottle in circular movements.
Look
what happened-
We turned the bottle in circular movements and the
water moved like a mini tornado. It spun faster and tighter at the bottom. The
glitter showed us which way the water spun. The spinning water made a water
vortex.
We found out that vortexes can be found in
tornadoes, hurricanes and waterspouts.
We asked these I
wonder questions.
I
wonder-
What
causes a tornado?
Kaelan found
out that when two air masses meet and the lower one contains warm humid air and
the higher one contains cool dry air, a tornado forms.
What
way does a tornado spin?
Madeline, Lily
and Nikita found out it depends which hemisphere you are in. It usually turns
counter clockwise in the northern hemisphere and clockwise in the southern
hemisphere .
Why
is in the dish washing liquid put in the bottle?.
Why
does it spin faster at the bottom?
How do you know when a tornado will
hit?

for same reason, the "cap," (the stable layer of air between the hot and cold air) is disturbed. The disturbance can be caused by an upper-level air disturbance,
When dad came in to class he made a marble go up down up down because he used a lot of tiny circular movements to make it fly.
Luke- Gravity is the force that pulls the liquid into the hole and a vortex develops.
