|
Mission 4 - Lesson 3: Where Hurricanes Get Their Energy Explain where a hurricane gets its energy, identify the conditions necessary for a hurricane to form, and explain what causes hurricanes to weaken. |

 |
Prepare |
|
|
|
Time required: 120 minutes
- For the extension discussion about Hurricanes and Global warming, you might want to provide each group of students with butcher paper to record their discussion.
- For the labs, you'll need to prepare all materials ahead of time. This list can be found in the student edition on page 73.

If you completed the Hurricanes and History connection, present your response to the class. If not, write a journal entry about how history might have been different if monster storms hadn't occurred.
Then, complete the Hurricanes and Global Warming extension. |

Instructions:
- Read "How Hurricanes Form" to a friend. While reading, you should try to synthesize the answer concisely to the question "How do Hurricanes Form?" You should be able to explain your answer in both words and pictures.
|
View
|
Find out the energy source and conditions required for a hurricane to form and strengthen. |
|
|
|
|
- Use the teacher's edition to facilitate class discussion.
|
|
Instructions:
-
Then, read the inset about the Hurricane Hunter aircraft on page 72 and compare and contrast that aircraft to the aircraft on page 34. Use the graphic organizer of your choice to make your comparisons.
|

|
See a photo of a Hurricane Hunter airplane and discover how it collects weather data by using onboard radar equipment and by launching data-transmitting probes called dropsondes. The technical specifications of the plane are also provided. |

|
Learn about the Lockheed ER-2 aircraft, used to collect weather data at high altitudes. Included is information about the craft's weight, speed, data collection instruments, and more. |
|
Instructions:
- With a partner, speculate on what the term "Wind Shear" means.
- Then, read the article "Why Hurricanes Weaken." This article begins on page 72 and then is continued on page 77. On page 77, only read the first paragraph and then stop reading.
- When you have finished reading, return to your partner to determine whether or not you were correct in your understanding of Wind Shear.
|
|
View
|
Discover how high wind shear, moving over cooler ocean water or land, and a change to the moist air can cause a hurricane to weaken or decay. |
|
Instructions:
- As an activity to understand Wind Shear, you will complete Lab 1: Wind Shear in Hurricanes. When you finish the lab, complete the Journal Question.
- This lab will take a whole class period, so make sure they review the lab procedures the night before. Follow all instructions in the teacher's edition.
- When students finish the lab, have them apply their inquiry skills with the extension activity at the bottom of the teacher's edition on page 73.

Wind shear is important to hurricane development. Jason Dunion and his colleagues look for light wind shear to help foster the growth of a monster storm. Without wind shear a convection
cell does not form, but too much wind shear can tear the storm apart. In this lab, you will build a model to examine the effects of wind shear on the updrafts that fuel a monster storm. |

To go with Mission 4, Lab 1. |
|
|
|
Describe the decay of a hurricane, using what you have learned from your reading and your experiments |
|
Instructions:
- This lab requires a particular set up. A walk through on how to set this up can be found in the teacher resources for Mission 4.

Reflect And Assess |
|
|
|
|
- This lesson provides several areas for assessment. You can use the lab questions and journal questions, and any products created from extensions.
- The critical thinking activity on page 75 is a great opportunity for students to consider what they have learned, and apply that knowledge.
|
|
|
|
 |
Follow-up |
|
|
|
|
- For homework, complete the journal activity assigned.The journal activity is found in the teacher's edition on page 78.
