1. TEACHER INFORMATION

2. TARGET AUDIENCE High School students (grades 9-12) that are interested in Engineering and the mechanical arts. Students open to learn about new things

3. LEARNING ENVIRONMENT This activity should be done in a computer lab so each student can have a turn on their own if possible. This can be done in small groups, but individually is recommended The working environment should be a quiet area There should be headphones available for each student

4. OBJECTIVES Students should be able to identify some of the components of the engineering process. Students should be able to demonstrate their knowledge by completing the quiz questions with an 80%+ accuracy.

7. SO WHAT IS ENGINEERING ANYWAY? Engineering is defined as “The branch of science and technology concerned with the design, building, and use of engines, machines, and structures. Engineering really is so much more than that! Engineering was involved in everything from this computer to the shoes you are wearing and the packaging they came in! http://novassembly.com/images/gears-animation.gif Back Next Home http://www.thevarguy.com/wp-content/uploads/2010/01/Oracle-Sun-Channel-Partners.jpg

8. WELL IF THAT IS ENGINEERING, WHAT IS TECHNOLOGY? Technology is defined as the application of scientific knowledge for practical purposes. When people think of technology they typically think of computers, phones, and other electronics. This is also a misconception. Technology is any tool created for practical purposes. This can be anything from a pencil to the design of your chair! http://novassembly.com/images/gears-animation.gif Back Next Home http://3.bp.blogspot.com/_4cUwhbTwT00/TLTRZEA-wBI/AAAAAAAAAIM/i487mmaxg3k/s1600/question_mark_guy.jpg

10. DRAFTING What is drafting? The systematic representation and dimensional specification of mechanical and architectural structures or designs Drafting is used to prepare a preliminary version of something It is used to fully express the details within a technical drawing. http://novassembly.com/images/gears-animation.gif Back Next Home

11. TYPES OF DRAFTING Three view Generally dimensioned and shows detail The complete shape of the object should be know by looking at this drawing alone http://novassembly.com/images/gears-animation.gif Back Next Home http://library.thinkquest.org/CR0214980/3viewstep4.JPG

12. TYPES OF DRAFTING Isometric View This is the same object in isometric, or 3D view. It is generally used to simply show what the final object will look like It is hard to dimension or show a lot of important details in this view http://novassembly.com/images/gears-animation.gif Back Next Home http://library.thinkquest.org/TQ0310106/isometricstep3.jpg

13. DIFFERENT LINE TYPES Solid line This line is used to show an edge in some fashion Hidden (dashed) line A hidden line is used to show a feature behind a solid surface Center line The center line is used to show the center of a circle or a curved surface http://novassembly.com/images/gears-animation.gif Back Next Home

14. YOU’VE TALKED ABOUT DIMENSIONING, SO WHAT IS IT? Dimensioning is to mark up a drawing or sketch with measurements This is used to convey specific information such as the size and location of the circle on this drawing to the right. http://novassembly.com/images/gears-animation.gif Back Next Home http://www.maelabs.ucsd.edu/mae_guides/cad/dimensioning/Dimensioning_Fundementals_files/image002.gif

18. APPLICATION QUESTION Which line represents a hidden feature? A. B. C. http://novassembly.com/images/gears-animation.gif Back Next Home

19. B. Is correct! This is called a hidden line (or dashed line) and it shows a feature that is hidden behind another! This is the end of the section, return to the home screen to choose a new one http://novassembly.com/images/gears-animation.gif Back Next Home

20. What is a prototype? A prototype is the original form or a preliminary version of something It is not a finished product but almost a working model of the original sketches It is an experimental model of whatever it is that you are designing PROTOTYPING http://novassembly.com/images/gears-animation.gif Back Next Home

21. WHY PROTOTYPE?! Prototyping is a cheap way to create a project or at least a preliminary representation of what the project will look like or how it will perform Prototyping saves money because it can point out potential flaws in the design earlier A prototype can also be used to present a product in order to raise money to create an actual version of it. http://novassembly.com/images/gears-animation.gif Back Next Home

22. BENEFITS OF PROTOTYPING Your prototype will be cheaper A prototype can be thrown together much faster than a final product A prototype is not meant to last but to show weak points in a http://novassembly.com/images/gears-animation.gif Back Next Home

24. APPLICATION QUESTION At what stage is prototyping used? A.At the beginning of a project, after brainstorming B.When a design is ready to be first tested C.When the product needs to be first presented D.All of the above http://novassembly.com/images/gears-animation.gif Back Next Home

25. D. ALL OF THE ABOVE Is correct! Prototyping can be done at virtually any stage in development depending on whether or not you need to test it for possible weaknesses or even present it! http://novassembly.com/images/gears-animation.gif Back Next Home This is the end of the section, return to the home screen to choose a new one

26. PRODUCT DESIGN How is a design started? A product is designed due to customer demand or A product is designed as a side project http://novassembly.com/images/gears-animation.gif Back Next Home

27. PROJECTS ARE NOT EASY Many times the customer is not happy with the product because it wasn’t made exactly how they wanted it, but they didn’t specify what they wanted close enough That is why it is important to ask many questions before you start a project to be sure it will be exactly to specifications http://novassembly.com/images/gears-animation.gif Back Next Home

28. Some products are very much trial and error and several were turned down upon first being presented. HOW TODAY’S PRODUCTS WERE CREATED Did glue used in sticky notes was a huge failure? It was supposed to be a strong glue and was later put on paper and found that it could be easily removed. It was still turned down when it was presented but was later accepted when it was seen being used around the office and made millions. http://novassembly.com/images/gears-animation.gif Back Next Home

30. APPLICATION QUESTION Is a design that does not meet customer needs usually the engineers fault? A.Yes, the engineer should know what the customer wanted B.No, the customer should have been more specific http://novassembly.com/images/gears-animation.gif Back Next Home

31. A. YES, THE ENGINEER SHOULD HAVE KNOWN WHAT THE CUSTOMER WANTED Is correct! Even if the customer wasn’t specific enough, it is the job of an engineer to find out exactly what they want even when the customer doesn’t know exactly what it is! The customer is always right! http://novassembly.com/images/gears-animation.gif Back Next Home This is the end of the section, return to the home screen to choose a new one
