3. Materials Tap water Scissors Ruler Paper clip Masking tape Black pepper Wooden spoon with a long handle
4. Steps of Investigation #1 First we started to stir and make the hurricane Next we added the black pepper Then we taped a paper clip to a ruler After doing that, we stirred the peppered water Then the water will make a funnel like shape, this looks like the eye of the hurricane We put the paper clip in the center of the hurricane which is the eye and it did not move
6. In the middle of the hurricane or the eye, there is no circular wind movement. It is calm.
7. Steps of Investigation of the eye wall First we put a piece of paper on the eye wall. Then we put a piece of paper on the outside of the bowl.
8. Eye Wall The eye wall spun around faster than the side of the hurricane.
9. Results and Conclusion When we put the paper in the middle and it moved to the eye wall it went past the tape more than the side Our Conclusion is the circular winds closer to the eye has the has the most speed.
10. Hurricanes What are hurricanes? Hurricanes are violent storms that develop from cyclones that form over a tropical ocean. The cyclone will pass through two stages before it becomes a hurricane. The first stage is a tropical depression. The next stage is a tropical storm and then it becomes a hurricane. In order for the storm to be called a hurricane the winds must exceed more than 75 mph.
11. Hurricanes are huge storms! They can be up to 600 miles across and have strong winds spiraling inward and upward at speeds of 75 to 200 mph. Each hurricane lasts for over a week, moving 10-20 miles per hour over the open ocean. With warm air at its center, a hurricane is different from extra tropical cyclones, which are the most common type of storm in the United States. The center of the storm is the calmest part. It is called the eye and has only light winds and fair weather. The low level storm winds blow counterclockwise in the Northern Hemisphere.
12. A hurricane is formed when a cyclone forms in late summer or early autumn over a tropical ocean where the water is above 80 F. The warm, moist air will rise rapidly letting the cooler air move in. Then the air will begin to spin and the air pressure in the center will drop. More air will get sucked in and the air will spin faster. Then the rapidly spinning air will rise into the shape of a doughnut and carry strong winds, rain, and clouds. Now a hurricane is formed.
13. This shows that in different areas of the world hurricanes are called typhoons, tropical cyclones, and hurricanes. Hurricanes are called something else in other parts of the world. They are called typhoons in parts of the southwest Pacific Ocean and southeast Indian Ocean, and tropical cyclones in other parts of the Indian Ocean.

15. To do this, they typically form between 5 to 15 degrees latitude north and south of the equator. Then, they thunder across the warm oceans of the world such as the Atlantic, the Gulf of Mexico, the Caribbean, and the Western Pacific Ocean (where they are called typhoons), up to higher latitudes.

18. Make sure you have a relative or friend in a different state to contact.
19. Make sure you know where to go if you have to evacuate and make sure your car has a full tank of gas.
20. Be sure you know how to turn off your utilities.
