It is almost dinnertime and your family decides they want to eat a pepperoni pizza. You tell your kitchen oven computer that you want a pepperoni pizza, then a list of the ingredients
appears on the screen. Perhaps you decide to add mushrooms, so you type in mushrooms, then hit enter. Ten minutes later, a bell rings, and the oven computer announces that dinner is
ready. You take the hot pepperoni pizza out of the oven and serve it to your family. Is there anything strange about this scene? Where did the ingredients for the pizza come from?
If scientists studying nanotechnology are correct, in the near future our food will be created out of atoms and molecules instead of being cultivated on farms. Once we know the molecular
structure of pepperoni pizza, we can use available atoms and molecules to build a pizza whenever we want. Nanotechnology is another name for molecular manufacturing - the science in
which things are built one atom or molecule at a time. Nanotechnology proposes the construction of molecular devices that will have the ability to manipulate atoms individually and
place them exactly where needed to produce the desired result. Scientists and researchers say this ability is almost here!
Your job in this WebQuest is to explore the world of nanotechnology. You will learn exactly how big a nanometer is, and why nanotechnology is named for a nanometer. You will find
out what a nanobot is, and what materials it may be made out of. You will learn why scientists think that nanotechnology will cause a revolution in the manufacturing and medical fields.
You will also discover the applications that scientists envision for nanotechnology. Finally you will answer a set of questions to demonstrate what you have learned about nanotechnology
in your exploration.
