Teacher Resource 4 
A hurricane is a very large storm that forms over tropical regions of both the Atlantic and Pacific Oceans. Rotating in a counter clockwise motion around a center, called an eye, hurricanes can reach speeds up to 200 miles per hour and measure 600 miles wide. Though a storm rages all around, in the eye of a hurricane, there are only light winds and the weather is rather calm. Hurricane season in the Atlantic is from June 1 to November 30 and May 15 to November 30 in the Pacific. Hurricanes need specific conditions in order to form. They need warm ocean water of 80 degrees or warmer, which gives the hurricane energy then causing more evaporation making storm clouds. The wind must be blowing in the same direction and hard enough to force air upward and away from the surface of the ocean. As the warm air rises, it gets cooler and cooler escaping through the top of the hurricane. A hurricane is able to travel because lighter winds outside the storm push it along and help it grow in size. They can travel up to 20 miles per hour over the open ocean and will stay active for more than a week. When a hurricane comes onto land, its strong winds and heavy rain can cause mild to severe damage depending on its size and strength. Hurricanes have storm surges, which cause flooding. Storm surges are large mounds of water gathered at the storms center by the rotating winds of the hurricane. There is a rating system called the Saffir-Simpson Hurricane Scale, which is used to determine how severe and what kind of damages a hurricane may cause. The scale has five categories. A category one hurricane has winds up to 95 miles per hour and causes only minimal damage. Category two hurricanes can reach wind speeds of 110 miles per hour and cause moderate damage. When a hurricane reaches category three winds can top out at 130 miles per hour causing extensive damage. A more severe hurricane is a category four. It has wind speeds up to 155 mile per hour and causes extreme damages to anything it touches. The worst hurricane is a category five. Winds in a category five hurricane are in excess of 155 miles per hour and damages are catastrophic, meaning the hurricane will destroy whatever lies in its path 
Teacher Resource 5 
A tornado is a funnel shaped column of air capable of causing mass destruction. Some people call tornadoes twisters or funnel clouds because of their shape and swirling motion however, a funnel cloud does not become a tornado until it touches the ground. Tornados rotate in a circle with violent wind speeds up to 300 miles per hour damaging anything in their path. On average, there are 1,000 tornadoes reported per year nationwide and their path of damage can be larger than 50 miles long and more than 1 mile wide. Most tornadoes form from thunderstorms. When moist warm air from the Gulf of Mexico and dry cool air from Canada meet, the atmosphere becomes unstable. As wind speeds increase and wind direction changes, an invisible horizontal spinning effect happens in the lower atmosphere. As air rises, the spinning tilts from a horizontal to a vertical position. This rotation will extend far and wide through the thunderstorm and this is where most tornadoes form. Tornado season is from March through May for southern parts of the United States and during the summer months for northern parts, occurring most often between the hours of 3 p.m. and 9 p.m. however, a tornado can form any time of the year, day, or night if conditions are right. Across all of the United States, the most common place for tornadoes to form accounting for more than 500 tornadoes per year is the Great Plains area. Because so many tornadoes form in this area each year, the Great Plains have taken the nickname “Tornado Alley.”

Activity Sheet 1 Please answer the questions after you read the passage in Teacher Resource Sheet 4 
A hurricane is a huge storm that can be up to 600 miles across. Hurricanes have strong winds that spin inward and upward, and range from 75 to 200 miles per hour. Hurricanes usually last about a week, traveling 10 to 20 miles per hour over the open ocean. The evaporating ocean water gives energy and heat to a hurricane. Hurricanes rotate counter-clockwise around the center of the storm called the “eye”. The eye of the storm is the calmest part; it has fair weather and light winds. Hurricanes only form over ocean water that is 80°F or warmer. These storms usually form between 5 to 15 degrees latitude north and south of the equator. When hurricanes hit land they bring lots of rain, high winds, and large waves that can cause a lot of damage to buildings, trees and cars. Please Answer the Questions: 1. How big are hurricanes? 2. Describe a hurricane.
