Here is my three sentences:

The science center is a hyperboloid. It is smooth with rounded edges and it is circular. It starts out with large circles at the bottom and gets smaller then it opens up again.

A Helix is a three-dimensional curve that lies on a cylinder or cone and cuts the elements at a constant angle. "Helix." New College Edition: The American
Heritage Dictionary. 1982 ed.
R(t) = [cos t, sin t, t]
This curve produces a helix that spirals up a cylinder at a constant angle t, 90 degrees.

A spring is a common thing most of us have seen.In the mathematics, it is called a helix. But imagine a helix that gets fatter as it gets taller.This shape is similar to a tornado. It would show the way wind spirals up a tornado.

My name is Son Tran, I am a student of Calculus III class.I have been using AutoCad release 14 to draw some shapes for our shows.Based on these shapes like sphere, torus, ellipsoidal, hyperboloid..... we want to help the kids of some Elementary schools to understand more some simple concepts about math.Through those shapes they can image the relationship between the common things and math.
