New Vocabulary Instability The sense of being uncertain. – Cylinder Circular shape – Classifications Grouping items together based upon their similarities – Simulation A product that is created to represent a separate event or circumstance – Fujita Scale A classification system that determines the strength of tornadoes – Materials/Resources: Choose one resource from each of the following categories to your shelter: Straws Craft sticks Spaghetti Noodles Construction Paper Cellophane Tape Wood Glue Content Information: Tornadoes are a forceful rotating wind storm that occurs when warm wet air mixes with cold dry air. When these two different types of air meet they create instability. This instability can then cause the air to spin and blow in different directions causing an updraft. When the tornado forms it will continue to spin and looks like a cylinder reaching from the sky to the ground. Tornadoes can come in different sizes and strengths depending upon the air type, temperature, rain, and wind. A tornadoes severity is measured on a Fujita scale. The following table explains the different strengths of tornadoes and their classifications. SCALE WIND POSSIBLE DAMAGE Light damage: Branches broken off trees; minor roof F0 40-72 mph damage Moderate damage: Trees snapped; mobile home F1 73-112 mph pushed off foundations; roofs damaged Considerable damage: Mobile demolished; trees F2 113-157 mph uprooted; strong built homes unroofed Severe damage: Trains overturned; cars lifted off the F3 158-206 mph ground; strong built homes have outside walls blown away Devastating damage: Houses leveled leaving piles of F4 207-260 mph debris; cars thrown 300 yards or more in the air Incredible damage: Strongly built homes completely F5 261-318 mph blown away; automobile-sized missiles generated Shelter and Weather Building a shelter that can withstand a tornado
