Attached is your assignment for the Scientific Method.
Product Descriptor for Scientific Method
You have learned the steps a good scientist uses when he wants to investigate a problem or answer a question
You will now illustrate the steps taken in an attractive way so it is easy for other members of the class to understand and see at a glance.
One way would to make a mobile out of a coat hanger. You may make it any way you choose.
The steps must be clearly marked and labeled.
An explanation of the steps must also be given.
If all steps have been shown
All explanations to steps shown 3
Work is neat and well displayed 3
If one step is missing 2
One explanation missing 2
Work is messy and not well displayed 2
The more work missing the lower your grades will be.
You must try to maintain a high level of neatness at all times
You will be working on your scenes. These need to be completed today
If complete with video get Background and Videos together.
Tracking hurricanes by meteorologists
You will view the video and answer the following questions
1. What do you notice about this segment of a forecast? What stands out?
4. What important terminology is used? This might be helpful for your storyboard!
2. What graphics and images are used in this segment?
5. Who appears in this segment? What do they do?
3. What is the overall purpose for this segment?
6. Further Observations?

Name: Plotting track of Hurricane Name of hurricane Where do hurricanes start and how do they form? Write a paragraph to explain each stage. Information to include wind speed and weather conditions Which land masses or islands did it hit and what was the damage. (Track of storm) What instruments do they drop into the storm to get information. What information does it send back to the aircraft? How Hurricanes Form and Die Hurricanes need four conditions to form:
- low air pressure
- warm temperatures
- moist ocean air
- tropical winds (near the equator).
Hurricanes form in the tropics, over warm ocean water (over 80ºF or 27ºC) and at latitudes between 8° and 20°, Hurricanes form mostly from June through November (hurricane season). These powerful storms are fueled by the heat energy that is released when water vapor condenses (turns into liquid water — rain). A hurricane goes through many stages as it develops:
- It starts as a tropical wave, a westward-moving area of low air pressure.
- As the warm, moist air over the ocean rises in the low air pressure area, cold air from above replaces it. This produces strong gusty winds, heavy rain and thunderclouds that is called a tropical disturbance.
- As the air pressure drops and there are sustained winds up to 38 miles per hour, it is called a tropical depression.
- The depression starts to spin.
- When the cyclonic winds have sustained speeds from 39 to 73 miles per hour, it is called a tropical storm (storms are given names when they begin to have winds of this speed).
- The storm becomes a hurricane when there are sustained winds of over 73 miles per hour.
The End of a Storm: When a hurricane travels over land or cold water, its energy source (warm water) is gone and the storm weakens, quickly dying. Hurricane Structure Hurricane winds blow in a counterclockwise spiral around the calm, roughly circular center called the eye. In the eye, which is roughly 20 to 30 miles wide, it is relatively calm and there is little or no rain. The eye is the warmest part of the storm. Surrounding the eye is the eyewall, a wall of thunderclouds. The eyewall has the most rain and the strongest winds of the storm, gusting up to 225 mph (360 km/h) in severe storms. The smaller the eye, the stronger the winds. The winds spiral in a counterclockwise direction into the storm’s low-pressure center. Long bands of rain clouds appear to spiral inward to the eyewall — these are called spiral rainbands. Hurricanes can be hundreds of miles across. In addition to rotating with wind speeds of at least 74 mph, a hurricane travels relatively slowly across the ocean or land, usually at about 20 to 25 mph. If you are facing in the direction that the hurricane is traveling, the right side generally has the fastest winds, and the left side usually has the most rain. Hurricane Classification and Extremes Hurricanes are classified into five categories based on current maximum wind speed. This rating scale is called the Saffir-Simpson Hurricane Scale, named for Herb Saffir and Robert Simpson, who developed it.
- Category 1 — Winds 74-95 mph
- Category 2 — Winds 96-110 mph
- Category 3 — Winds 111-130 mph
- Category 4 — Winds 131-155 mph
- Category 5 — Winds over 155 mph (these are VERY rare)
Fortunately, there are very few Category 5 storms; most storms that achieve Category 5 status only hit Category 5 status for a very short time, then the winds subside to a less powerful level. Some of the strongest recent hurricanes (Atlantic Ocean tropical cyclones) that hit Category 5 status include:
