HURRICANES
A hurricane can be compared to a tornado in water. The makings of a hurricane starts off as a tropical storm, with winds of 39-73 miles per hour. When the winds advance to above 74 mph it is considered a hurricane. Hurricanes can be very devastating if it hits land. For example Hurricane Katrina hit America in 2005 and left many states in a stage of disaster.
Attached is a link of a game that can help students better understand hurricanes.

Fun Rain Facts!
What
causes rain?
When clouds develop or rain occurs, something is making the air rise. Several things can make this happen. Mountains, low-pressure areas, cold fronts, and even the jet stream.
How big are raindrops?
Raindrops are much smaller than we think! They are actually smaller than a centimeter. Raindrops range from 1/100 inch to 1/4 inch in diameter.

Raindrops are much smaller than we think! They are actually smaller than a centimeter. Raindrops range from 1/100 inch to 1/4 inch in diameter.
Not including
wind-driven rain, raindrops fall between 7 and 18 miles per hour (3 and 8
meters per second) in still air. The range in speed depends on the the size of
the raindrop. Air friction breaks up raindrops when they exceed 18 miles per
hour.
Thunder and Lightening
Thunder and lightening and what they are caused by!
What causes lightning?
Lightning is an electric current. Within a thundercloud way up in the sky, many small bits of ice (frozen raindrops) bump into each other as they move around in the air. All of those collisions create an electric charge. After a while, the whole cloud fills up with electrical charges. The positive charges or protons form at the top of the cloud and the negative charges or electrons form at the bottom of the cloud. Since opposites attract, that causes a positive charge to build up on the ground beneath the cloud. The grounds electrical charge concentrates around anything that sticks up, such as mountains, people, or single trees. The charge coming up from these points eventually connects with a charge reaching down from the clouds and - zap - lightning strikes!
What causes thunder?
Thunder is caused by lightning. When a lightning bolt travels from the cloud to the ground it actually opens up a little hole in the air, called a channel. Once then light is gone the air collapses back in and creates a sound wave that we hear as thunder. The reason we see lightning before we hear thunder is because light travels faster than sound!
Here is a link to a website that will show you where lightening is currently striking in the United States.

TORNADOS
A tornado is a violently rotating
funnel of air that descends from a thunderstorm. Tornados are able to form when three
different types of air are combined, these types of air are; warm/humid, cold,
and dry. A combination of layers of
these different airs cause a push upward forming a funnel. 
Attached is a fun game for students to play so they can
understand a little more about tornados and their effects on a community.
