Materials Tap water Scissors Ruler Paper clip Masking tape Black pepper Wooden spoon with a long handle
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
Pictures of the Investigation
In the middle of the hurricane or the eye, there is no circular wind movement. It is calm.
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.
Eye Wall The eye wall spun around faster than the side of the hurricane.
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.
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.
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.
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.
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.
This shows where hurricanes, typhoons, and cyclones are formed. Hurricanes do an important job for the Earth. They help move heat from warm tropical places to the cooler temperate zone.
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.
Hurricanes happen when the oceans have been warmed during summer months. In the North Atlantic, hurricane season is from June 1 to November 30, but most hurricanes happen during the fall.
Wetlands : Nature's Speedbumps
Scientific studies by the Army Corps of Engineers suggest that every 2.7 miles of wetlands can reduce deadly storm surges by a foot (source: America’s Wetland).
We need to save the wetlands along the coasts where hurricanes come ashore. Not only are they valuable ecosystems for animals, they also keep hurricane s from being so destructive.
Make sure you have a Family Safety Kit with bottled water, canned food that is fresh, good batteries, and updated medicine.
Make sure you have a relative or friend in a different state to contact.
Make sure you know where to go if you have to evacuate and make sure your car has a full tank of gas.
Be sure you know how to turn off your utilities.
Be sure you have money in the house.
If the weather channel declares a hurricane watch, listen for further information.
Bring in all objects that could blow away.
Windows, doors, and skylights should be secured.
Have extra food and drink in the house.
Bring all pets inside.
What we learned about God What we learned about God is that he has more power to make a hurricane and to make a certain part of a hurricane calmer than anything else.
