  1. Saving Freddie An introduction to the Engineering Process

  2. How can we help Freddie the Worm put on his lifesaver using only paper clips? Key Question

  3. An engineer solves problems with given constraints. You will work in teams of two and use the steps of the engineering design process. • You will define the problem, list criteria for success, brain storm possible solutions and test and evaluate solutions. • The final solution will be communicated orally to another group and a written report will be prepared to share your solution with other engineers. Learning Goals

  4. The Problem The canoe has capsized. The lifesaver Freddie needs is under the canoe.He needs help to retrieve his lifesaver. Freddie cannot swim!

  5. Constraints Engineers cannot touch the cup, Freddie or his lifesaver. Engineers can use the paperclips.

  6. Freddie and his lifesaver cannot be damaged. • Freddie cannot fall into the water. • The lifesaver must be around Freddie’s middle. Criteria for Success

  7. Step-by-Step Instructions

  8. State the Question – What problem are you trying to solve? How can we help Freddie the Worm put on his lifesaver using only paper clips? State the Question – What problem are you trying to solve?

  9. Topic Sentence – Tell your reader what these steps will accomplish. We will solve Freddie’s problem and help him find his lifesaver and put it on. Topic Sentence – Tell your reader what these steps will accomplish.

  10. Constraints – Explain to your reader what constraints you had for this problem. One constraint for this problem is that we cannot touch Freddie, the canoe or the lifesaver with our hands. The other constraint is that we can only use two paperclips as tools for the rescue. Constraints – Explain to your reader what constraints you had for this problem.

  11. Criteria for Success - Explain to your reader what criteria will define the successful solution to the problem. The criteria for success are that Freddie and the lifesaver cannot be damaged in any way and the lifesaver must be around his middle. Criteria for Success - Explain to your reader what criteria will define the successful solution to the problem.

  12. Step 1 Open the paperclips so they are “S” shaped. Step 1

  13. Step 2 Use the paperclips to gently lift the canoe and retrieve the lifesaver. Step 2

  14. Step 3 Stretch the lifesaver so that Freddie can fit inside easily. Continue sliding Freddie inside the lifesaver until it is securely around his middle. Step 3

  15. Conclusion – Restate your topic sentence Freddie is easily saved when we help him put on his lifesaver. Conclusion – Restate your topic sentence

  16. Transitions

  17. Some sample transition words • First, second, third… • First, next, then, finally… • Afterwards, later, during, while Transitions

  18. Polished Piece Your graphic organizer is your rough draft. Write the polished piece as a single paragraph.
