I retrieved this photo from Taca on Picasso Web Albums on Google.  This is a picture of a funnel cloud that is about to touch down and form a tornado.  In my lesson, I would use this photo to discuss the difference between a funnel cloud and a tornado.  I would also discuss the spinning motion which  this pictures demonstrates.  Plus, this picture is a great attention getter because it does not look like a normal tornado. 

The picture down below is pretty amazing.  This picture is great to show the students because one, it shows what Dallas looked like many years ago and two, it demonstrates a how the tornado is touching down.  I would use this picture to start a discussion on how we need to have buildings that can withstand the high powered winds of a tornado.  This would lead to the students learning about lateral forces and upward forces.
