1. Product Evolution Jerry Nelson IED September 15 th 2010 Change over Time

2. Define the Problem Analyze the evolution of a product and trace it from its beginning to its current use or end. Then select a product from a hobby or interest that has undergone noticeable improvements over some time period.

3. Brainstorming Four Wheelers Camping Guns Trucks Knives Shoes Motorcycles Bicycles Cameras Clocks

7. Select an Approach Final Project is on the Change in Clocks Throughout History Reasons: Decision Matrix Results Long Time Interest Want to Learn More

8. Develop a Design Proposal Create a timeline and history of Clocks Change in Clocks Throughout History ◦ A clock is an instrument used to indicate, keep, and co-ordinate time ◦ “Clock" refers to any device for measuring and displaying the time.

9. Develop a Design Proposal Early Clocks ◦ Sun Dials – Used the movement of the sun to move the shadow across the face of the clock ◦ Water Clocks - Water clocks were among the earliest timekeepers that did not depend on the observation of celestial bodies ◦ Sand Clocks - An hourglass (sandglass, sand timer, sand clock) measures the passage of a few minutes or an hour of time

10. Develop a Design Proposal Pendulum and Spring Clocks ◦ The pendulum clock was invented in 1656 by Dutch scientist Christiaan Huygens, and patented the following year. ◦ Earliest pendulum clocks used weights to power the clock ◦ Windup clocks have been around for nearly 400 years. When they were first invented, windup clocks were the most advanced machines of the time.

11. Develop a Design Proposal Modern Age - Digital and Quartz ◦ Quartz - A quartz clock is a clock that uses an electronic oscillator that is regulated by a quartz crystal to keep time ◦ LED -A light-emitting diode, LEDs are used as indicator lamps in many devices, and are increasingly used for lighting ◦ LCD - A liquid crystal display (LCD) is a thin, flat electronic visual display that uses the light modulating properties of liquid crystals

12. Model or Prototype “Timeline” Seth Thomas Mantle Clock early 1800’s Yuan Dynasty water clock from the 13th century Galileo Pendulum clock 1637. Spring Wound Seikosha Wall Clock 1920 Sycamore Wind Up Alarm Clock 1980 Digital LCD clock with LED backlight 2010

13. Test and Evaluate Students, friends and family critique Refine Fix all problems found during the critique Create or Make Put together the final time line and report Communicate Results Turn in PowerPoint, Technical Write up and Video
