My Project

Due Date:
My investigation is about: Which roof has the strongest resistance to hurricane force wind, common, barn, or round.

7th November
My hypothesis is: The round roof will have the strongest resistance to hurricane force winds.

7th November
My references used to research the question:

7th November
Materials and equipment required to conduct my investigation:
1. fan
2. massing balance
3. three different types of roofs on houses (common, barn, and round)

14th November
My experimental design (the method you will use to test your hypothesis):
I will determine how much "lift" the fan's strongest wind has on the various roofs. I will place each house on a massing balance,
with the fan turned on. I will see how much lighter the houses get. I will also try the fan at different angles. I will then make a graph
of my observations.

14th November
Conduct experiments and submit quantitative data and graphs.

Speeds of Hurricane Winds
Level 1: 74-95 mph
Level 2: 96-110 mph
Level 3: 111-130 mph
Level 4: 131-155 mph
Level 5: 156 mph
Some winds can go up to 200 mph.
Wind can create serious damage to roofs.

Roof Types
The "Roof Type" is the slope of you roof.

- 11 tropical storms
develop over the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico
- about 5 strike the US coastline, killing 50 to 100 people
- usually 2 become major or intense hurricanes

Tropical Depression
An organized system of clouds and thunderstorms with a defined surface circulation

Tropical Storm
An organized system of strong thunderstorms with a defined surface circulation

a type of tropical cyclone, which is a generic term for a low pressure system that generally forms in the tropics. The cyclone is accompanied by thunderstorms and, in the Northern Hemisphere, a counterclockwise circulation of winds near the earth's surface.

- greatest danger of a hurricane is flying debris
- concrete homes resist hurricane winds the best

- roof is usually blown away first in when a hurricane strikes a house
- roofs aren't slipped away sideways, they are lifted up from the walls
