This week we are learning a bout hurricanes.
Luckily, YOOPERS don't have to worry about hurricanes. Lake Superior isn't warm enough to start the engine.
The three things needed for a hurricane to form are:
1) Warm water (Think bath water).
2) Warm, humid air.
3) Steady wind.
The warm water heats up the air above it and causes it to rise. It is full of water. When it gets high in the atmosphere, it spreads out and begins to cool. The space left by the warm, humid air leaving is quickly replaced. That air rises and begins the "engine." Gusty wind will break the process apart before it can become a hurricane, but a steady wind will set the conditions for a massive, destructive storm.
Watch a good video here.
I was even able to find an Emergency Alert from the National Weather Service to make the "evacuation" more real. I have a HUGE fan in my room to help keep it cool on hot days. Today it rocked us like a Hurricane (I had too...). :)
In class we learned about how a hurricane is formed, we made a hurricane with bodies, and then we build hurricane proof shelters.
....then we blew them down!
Great lesson and great fun!
