Introduction-

Tornadoes go by many different names such as twisters, dust devils, and whirlwinds.  Tornado actually comes from the Spanish word, tronada, which means thunderstorm.  A tornado can occur at anytime during the year and in any section of the country.  It is a twisting column of air that touches the ground.  The average tornado is 400 to 500 feet wide and has winds less than 112 miles per hour.   It usually only lasts a few minutes, but is extremely powerful and can lift many things off the ground.  Tornadoes are very violent and severe storms that can be dangerous.  Students will research and find out more about tornadoes.

Process-

• Students will decide and break up into groups.

• Decide which student will be cartographers and tornado trackers.

• Research and find everything you can about a specific tornado that occurred in a specific area.

• Work together and practice your presentation.

• Construct your tornado with whatever materials you would like to use.  Be creative.

Evaluation-

Students will be graded on their presentation and the construction of their tornado.  A rubric will be used and is out of 100 points.  It is as follows:

Presentation:  Group participated equally and worked well together.                                    20

The presentation was clear and easy to understand.                                       20

The information presented was informational and accurate.                            20

Direction were followed and completed on time.                                            20

Construction of tornado:  Unique and descriptive.                                                                10

Conclusion-

The project and presentation should help students to understand tornadoes and how unpredictable they are.  They should understand the deadly effects of tornadoes, but also the mysterious formation of nature.  The students should have an understanding of tornadoes and how different areas of the country have different kinds of storms.  Group presentations will also help the students learn more about each other and themselves.  The will develop more confidence speaking and relating to peers.
