  1. Engineering Lessons Quarter 3

  2. February 3, 2014 • Do Now: In your engineering Journal remember to RTQ and put in the date. Use the back of the paper. • What different things can we measure? • Do you think measurement is difficult or easy? Explain. • Why is it important to have a standard unit of measurement?

  3. February 4, 2014 • Do Now: • In your Engineering Journal • What do engineers do? • Engineers make improvements to products to make them better • Why are engineers important? • Engineers make our lives easier. • Have you ever had a problem with something you bought and thought of a way to change it to make it better? Explain.

  4. February 4, 2014 • Understand the design process. • Do Now • Notes on The Engineering Design Process • Practice with the Engineering Design Process • Reflection Objective Agenda

  5. Engineering Design Process • During the engineering design process you will jump around between steps and not always work in order. This is called iteration.

  6. 1. Define the Problem • Ask questions about the problem you observe • What is the problem or need? • Who has the problem or need? • Why is it important to solve? • Who needs what because of why?

  7. 2. Do Background Research • Learn from others and research users and customers or existing solutions.

  8. 3. Specify Requierments • Find the requirements you must follow for your product • How much time do you have? • What size must it be? • Are there any extra things you need to make sure you add?

  9. 4. Brainstorm Solutions • Try to think of as many solutions to your problem that you can, no matter how outrageous they may be.

  10. 5. Choose the Best Solution • Look at all of your solutions and pick the solution that best fits your design requirements.

  11. 6. Develop the Solution • Keep improving the solution. This will continue through the design process.

  12. 7. Build a Prototype • This is a model of the final product but is not as polished.

  13. 8. Test and Redesign • Test your product and make changes • This will continue through the design process • This is the most important step.

  14. 9. Communicate the Results • Communicate your results to others so that others can repeat what you did.

  16. Think about this: • You work for the Beats company. Many people have been writing to you complaining that their Beats head phones have not been working because of the cold weather. • Define the problem • Brainstorm Solutions • Pick a solution • Sketch a prototype

  17. February 5, 2014 • Do Now: • In your Engineering Journal • What do you think it means when Mrs. Burke says you will be graded on “Lab Skills”? • What are some important Lab skills you would need to remember in the classroom? • What are some important skills you need to use while you are working with a group of people?

  18. February 5, 2013 • Do Now • Marshmallow Challenge • Reflection Objective Agenda

  19. Marshmallow Challenge • In groups of 4 • 18 min • Create the tallest free standing tower • Must balance the marshmallow on top • Materials: • 20 sticks of spaghetti • 1 yard of tape • 1 yard of string • 1 marshmallow

  20. Reflection • What worked on your tower? • What did not work on your tower? • What changes would you make on your tower in the future?

  21. Pioneers

  22. Raiders

  23. Badgers

  24. February 6, 2014 • Do Now: • In your Engineering Journal • Draw a prototype of the tower design you would like to build with your group today. Label all of the parts!

  30. Reflection • Was your tower better today or yesterday? Why? • What worked on your tower? • What did not work on your tower? • What changes would you make on your tower in the future?

  31. February 10, 2014 • Do Now: • In your Engineering Journal answer in complete sentences. • What do you think of when you hear the word machine? • How do you use machines everyday? • List machines that you use everyday.

  32. February 10, 2014 • Distinguish among the different simple machines • Do Now • Simple and Compound machines • Simple Machine Notes Objective Agenda

  33. Machines • Simple Machine • A machine that does work in one movement • Compound Machine • Made of a combination of simple machines

  34. Independent Work • Read 591 – 593 about the simple machines • Inclined Plane • Wedge • Screw • In your journal • Define • Give an example • Draw a sketch

  35. February 11, 2014 • Do Now: • In your Engineering Journal write the date and answer in complete sentences • How do machines help us? • Would work be easier or more difficult with out machines? Explain? • How many simple machines are there?

  36. February 11, 2014 • Distinguish among the different simple machines • Do Now • Simple Machines • Bill Nye Objective Agenda

  37. Independent Work • Read 594 – 597 about the simple machines • Lever • Wheel and Axle • Pulley • In your journal • Define • Give an example • Draw a sketch • http://www.youtube.com/watch?v=0LnkviArKBA

  41. February 13, 2014 • Do Now: • On a separate piece of paper • W = F x d • A force of 15 newtons is used to push a box along the floor a distance of 3 meters. How much work was being done? • Amy uses 20 N of force to push a lawnmower 10 meters. How much work does she do? • If I am pushing on a car with 300N of force and it does not move is any work being done?
