Lesson Plan Title: All About Hurricanes Concept / Topic To Teach: Hurricanes Standards Addressed: Social Studies Standard 1.4 demonstrate an understanding of geographical space and place.  Grade 3: Identify and locate Earth's various physical features (e.g., continents, oceans, and mountains.)

General Goal(s): For students to: -Understand about hurricanes, and how they work. -Understand how they are measured. -How to prepare for a hurricane. -The effects after a hurricane has finished. Talk about Katrina.

Specific Objectives:The students will have an assessment where they are given a scenario of a hurricane coming. They will have to describe how they will prepare for safety based on the level of the hurricane.

Required Materials: -Videos -Pictures -Assessment -Vocab: ~Hurricane: a violent, tropical, cyclonic storm of the western North Atlantic, having wind speeds of or in excess of 72 mph (32 m/sec). ~Eye: the approximately circular region of relatively light winds and fair weather found at the center of a severe tropical cyclone. ~Coriolis Effect: the apparent deflection (Coriolis acceleration) of a body in motion with respect to the earth, as seen by an observer on the earth, attributed to a fictitious force (Coriolis force) but actually caused by the rotation of the earth and appearing as a deflection to the right in the Northern Hemisphere and a deflection to the left in the Southern Hemisphere. ~Cyclone: a large-scale, atmospheric wind-and-pressure system characterized by low pressure at its center and by circular wind motion, counterclockwise in the Northern Hemisphere, clockwise in the Southern Hemisphere. ~High Pressure System: An area of relative pressure maximum that has diverging winds and a rotation opposite to the earth's rotation. This is clockwise the in Northern Hemisphere and counterclockwise in the Southern Hemisphere. It is the opposite of an area of low pressure or a cyclone. ~Low Pressure System: An area of a relative pressure minimum that has converging winds and rotates in the same direction as the earth. This is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Also known as an cyclone, it is the opposite of an area of high pressure, or a anticyclone. ~Tropical Depression: A tropical cyclone in which the maximum sustained surface winds are 38 miles per hour (33 knots) or less. ~Tropical Storm: A tropical cyclone in which the maximum sustained surface winds are from 39 miles per hour (34 knots) to 73 miles per hour (63 knots). At this point, the system is given a name to identify and track it. **~**Tropical Storm Watch - Tropical Storm conditions with sustained winds from 39 -74 mph are possible in your area within the next 36 hours. Tropical Storm Warning - Tropical Storm conditions are expected in your area within the next 24 hours. Hurricane Watch - Hurricane conditions with sustained winds of 74 mph or greater are possible in your area within the next 36 hours. This WATCH should trigger your family's disaster plan, and protective measures should be initiated. Especially, if those actions that require extra time such as securing a boat and leaving a barrier island. Hurricane Warning - Hurricane conditions are expected in your area within 24 hours. Once this WARNING has been issued, your family should be in the process of completing protective actions and deciding the safest location to be during the storm.

Anticipatory Set (Lead-In): Start off by asking students what they know about hurricanes before I show them a video on Discovery Channel website. [|Hurricanes Explained Video]

Step-By-Step Procedures: 1. Ask students about prior knowledge of hurricanes. 2. Show video about how Hurricanes develop. Use Weather Wiz Kids Site for tasks 3-9. For pictures info and links. Pics and charts seen from this website also. 3.Talk about what a Hurricane is. Show [|before and after pictures] Hurricane Ike. [|Before and after] Hurricane Katrina. 4. Talk about how a hurricane forms. 5. Talk about the hurricane season where and when it starts for us.

6. Mention about how hurricanes are named. Started out as phonetic alphabet, then women's names, and finally alternated between men and women names. 7. Talk about the hurricane stages.
 * Tropical Wave || A low pressure trough moving generally westward with the trade winds. ||
 * Tropical Disturbance || An organized area of thunderstorms that usually forms in the tropics. Typically, they maintain their identity for 24 hours and are accompanied by heavy rains and gusty winds. ||
 * Tropical Cyclone || A generic term for any organized low pressure that develops over tropical and sometimes sub-tropical waters. Tropical depressions, tropical storms, and hurricanes are all example of tropical cyclones. ||
 * Tropical Depression || An organized area of low pressure in which sustained winds are 38 mph or less. ||
 * Tropical Storm || A tropical cyclone with maximum sustained wind speeds that range from 39 to 73 mph. ||
 * Hurricane || A tropical cyclone with sustained winds of at least 74 mph. ||

8. Saffir-Simpson Hurricane Scale
__(Feet)__ || __Damage__ || 9. Talk about Hurricane safety and [|supplies] to have depending on the category. 10.[| Assessment]: Give students packet and have them take the two little quizzes at the end and hand them in.
 * __Category__ || __Winds (MPH)__ || __Pressure (Millibars)__ || __Pressure__ __(Inches)__ || __Storm Surge__
 * 1 || 74-95 || <980 || <28.94 || 4'-5' || Minimal ||
 * 2 || 96-110 || 979-965 || 28.91-28.50 || 6'-8' || Moderate ||
 * 3 || 111-130 || 964-945 || 28.47-27.91 || 9'-12' || Extensive ||
 * 4 || 131-155 || 944-920 || 27.88-27.17 || 13'-18' || Extreme ||
 * 5 || >155 || <920 || <27.17 || >18' || Catastrophic ||

Plan For Independent Practice: Students will read over the packet and do the quiz on their own. Closure (Reflect Anticipatory Set):After the packet and quiz work is done, I will ask students to raise their hands and tell me something they learned about hurricanes during that lesson to see what they remember. Assessment Based On Objectives:Assessment tells and asks about how hurricanes work, how they are measured. It utilizes what my objectives are to see how much they have learned. Adaptations (For Students With Learning Disabilities):Give the student a worksheet with some of the information and charts so they can follow along better. Possible Connections To Other Subjects:Can tie into science because hurricanes have scientific ideas about them.
