Use the ideas and resources below to create lessons and help students participate in activities which will enrich their clock design process as they learn more about the history of time keeping, the way clocks work, discover some individuals with the inventive spirit and find out about the process which helps protect creative or intellectual property.
In order to think about a new way to look at measuring time students may find it interesting to see how time has been measured, how our calendars have changed, and why the devices we use to mark time were developed.
Help students find some of the discussions about when the new Millennium begins. Some say the new millennium began on January 1, 2000; others say it begins on January 1, 2001. Still others say the new millennium has already passed. The only thing that seems to be agreed upon is the actual definition of millennium, i.e., a thousand year period of time.
The links below will help answer the questions about the new Millennium.

Students may suggest ideas about ways to indicate measures of time that they feel should be used that may not have been used before. They may brainstorm ideas about ways of marking periods of time which they think would be helpful in the future.
Take a look at these sites to discover the history of time and time keeping devices. These may help students devlop ideas for future time keeping devices:

New and unique ideas deserve protection. The U.S. Patent Office has been granting inventors of ideas, devices, designs and processes an award called a patent. A patent will protect the inventor from anyone being able to make, sell or take their original ideas for 20 years.Learn more about patents with this easy to read article called What is a Patent? Have students try an online quiz about patents after they read the article.
Your class will receive a Millennium Clock Virtual Online Patent when they complete and submit their project. You will receive email notification for the URL which will allow you to print out copies of the patent for all students involved in the project.
Here are some online resources to help students learn more about the patent process.

You might want to take this opportunity to discuss the role of women and how their contributions have been important to our way of life and economy. Early women inventors were often not able to patent inventions in their own names and sometimes their husbands or others males had to get patents for them. Here are some web sites which discuss women inventors:
