Objective: I will participate in an introductory activity to engineering and begin to understand its process.

- All engineers use a method when they are designing. - Just like scientists, engineers follow steps. - How might this system work at the right for designing a bridge?

How can I build a bridge using the best design for it’s use.

Think about your numerous over bridges in a car or walking…… What do you think are important features in a bridge?

Picture with details Bridge

Pick one solution. Your group will look at your initial ideas and analyze the pros and cons. With different opinions it might help to make a good change that you did not think of for your bridge.

Supply options: - Popsicle sticks - Straws - Toothpicks - Twine - Glue - Packaging peanuts - tape

At this point most engineers would NOT have been successful and have to start the process over again until they get it right.

 A failure to success story… In 1968, Dr. Spencer Silver, a scientist at 3M in the United States, accidentally developed a "low-tack", reusable, pressure sensitive adhesive. [1] For five years, Silver promoted his invention within 3M, both informally and through seminars, but without much success. In 1974, a colleague of his, Art Fry, who had attended one of Silver's seminars, came up with the idea of using the adhesive to anchor his bookmark in his hymnbook. [2][3] Fry then developed the idea by taking advantage of 3M's officially sanctioned "permitted bootlegging" policy. [3] 3M launched the product in 1977, but it failed, as consumers had not tried it. [4] A year later, 3M issued free samples to residents of Boise, Idaho, and 90 percent of the people who tried them said that they would buy the product. By 1980, the product was being sold nationwide in the US; [4] in 1981 Post-its were launched in Canada and EuropeSpencer Silverpressure sensitive adhesive [1]Art Fry [2][3]bootlegging [3] [4]Boise, Idaho [4]CanadaEurope

 You have $100,000 to build your bridge. You need to submit a design proposal to Mrs. Prax before you can begin.  Your Design Proposal must include:  Cost Analysis of supplies  Drawing of bridge  Explanation of what supplies you chose and why  As you complete your bridge, your proposal will change. Make sure to stay on budget. You can return any unused materials.  Material Cost: Popsicle stick: $1000Toothpick: $500Straw: $750 Meter of string: $200Packing Peanut: $200Glue: $500 Regular tape: $1000 per meter Packing tape: $1500 per meter
