1 Engineering Concepts Elective Copyright 1996 Karen Falkenberg Emory College Atlanta, Georgia Course description This interdisciplinary elective is designed for students who have had two years of both science and mathematics through algebra 2. The course incorporates curriculum in science, math, and writing. Topics include structure design, electronics, construction of prototypes, marketing, and an introduction to patents. Primarily group project-driven, the course emphasizes teamwork, oral presentations, technical writing, and time management for long range projects in which students learn how to organize real-world information to develop unique solutions to open-ended problems. The course culminates with a nine-week project comprised of designing a novel product, building a prototype, and developing a marketing strategy to attack a real-world problem such as helping the handicapped, preventing crime, or eliminating a safety problem. Course goals To introduce the world of open-ended problem solving to a group of varied ability students. To stress the interdisciplinary nature of the problems encountered in the business world. To use concepts from civil engineering, electrical engineering, mechanical engineering, and marketing. To be committed to alternative assessment in this course. There are no written individual paper exams. To have students develop teamwork skills and individual accountability. To have students learn time management because there is no distinction between class work and homework. To emphasize communication through improved proficiency in technical writing and oral presentations. To allow students to be primarily responsible for their own learning. The teacher will not be the leader of the class. To be project-driven with students of varied abilities, strengths, and interests working together. To be sensitive to gender differences and encourage young women to feel comfortable being leaders on engineering projects. Course timetable 1 week on introduction to problem solving: redefining the problem, recognizing bias, developing alternatives, defining, quantifiying and justifying specifications, using a matrix to organize alternatives 6 weeks on structures culminating with bridge testing of constructed truss bridge 6 weeks on electronics culminating with individual projects in chosen area of electronics/electricity 4 weeks on development of working device to solve a teacher-selected problem 9 weeks on marketing, new product development and patents all taught by groups of students; weekly group marketing projects are submitted 8 weeks on final project: development of novel device and marketing strategy to address a community problem such as helping the handicapped, crime prevention, identifying and working on environmental problems.

6 Powerlifting Your group s objective will be to design and build a device that lifts sand. This packet of information covers all aspects of the project. We will begin on Tuesday, November 15 and end with a technical review on December 15. The problem and the specifications On December 15, your group will operate a device that you have constructed. The device should be designed to lift as much sand as high as possible in a ten-minute period. You may attempt to lift up to 100 pounds but the sand needs to be collected so that it can be reused. (The sand will be provided for you.) You will be able to examine the holding vessel that will contain the sand. You may use no other energy source except the wind energy of the fan provided. These are the constraints applied to the construction and operation of your device. The device must: 1. fit in the Webb School Gym 2. be constructed of materials that cost no more than $90. $20 will be supplied by Webb School course budget. (You must purchase supplies and then submit the original receipt for reimbursement. Staple the original receipts to a paper with a description that details what the purchase was and what it was used for. If you lose the receipt, you lose the reimbursement.) Up to $30 may be contributed by group members; up to $40 of borrowed materials may be used. (You should accurately estimate the worth of a piece of equipment or the supplies that you would like to use that you do not need to buy. Fill out a Supply Cost Form and submit it to Mrs. Falkenberg for verification prior to using the equipment or supplies.) 3. operate in such a way that the sand can easily be collected for reuse 4. use no other energy source except the wind energy of the fan provided 5. be able to run unassisted 6. operate in a safe manner without injury to anyone or damage to the gym

7 Time Management There are 5 phases of this project. To assist you in planning, I have listed significant tasks for each phase. In addition, I have given suggested dates for each phase. Do NOT wait until the last minute to complete a task. Be sure to spend adequate time out of class to complete work. Preliminary: Start 11/15, End 11/16 1. assess existing talents within the group 2. determine current level of knowledge of simple machines, potential and kinetic energy Brainstorming and idea generation: Start 11/15, End 11/22 1. use alternative resources such as the library, the phone, outside professionals, etc., to expand your knowledge of: simple machines, mechanical advantage, potential energy, and kinetic energy 2. use this information to help you brainstorm ideas for accomplishing the sand lifting 3. use a matrix to organize brainstormed ideas and rank according to specifications Construction: Start 11/22, end by 12/7 (last minute adjustments after that time should be minimal) 1. determine materials needed 2. assess methods for accruing borrowed materials 3. gather purchased and borrowed materials 4. construct and TEST device 5. evaluate success of device 6. go back to step 4 and iterate until successful Reporting: Start 11/28, end 12/7 (last minute adjustments after that time should be minimal) 1. write draft of written report 2. edit and finalize written report 3. produce PowerPoint slides 4. organize formal presentation 5. PRACTICE PRESENTATION Final: 1. be ready to give preliminary presentation on Dec 8 or 9 as assigned 2. turn in copies of final report on Dec make last minute adjustments to device if necessary 4. be on time for technical review Dec 15 Throughout this project, coordination of responsibilities will be essential. It is MANDATORY that the group have tasks divided equitably among members. At the end of this project, you will be asked to assess the effort level of each member in the group and grades will adjusted reflect each member s contribution. Assessment Your group will be assessed according to how well you meet the following objectives. My objectives for each group for this project are: 1. Equitable distribution of work among group members 2. Time management proficiency for a one month project 3. Demonstrated increase in students technical understanding of simple machines, mechanical advantage, energy conversion 4. Evidence of creative brainstorming ranked in a matrix against design specifications 5. Use of outside resources for assistance (library, phone, etc.) 6. Application of technical information in construction of device 7. Construction of a novel device and troubleshooting mechanical problems 8. Proficiency in written and oral technical reporting 9. Increased level of presentation skills for all students

8 Marketing and New Product Development In this segment of the course, we will be studying marketing and the business of new products. We will consider how ideas are transformed into new products and how products are introduced into the marketplace. Marketing strategies and business ethics, how markets are affected by consumer behavior, and how to segment the market to get the right consumer will also be covered. We will finish this unit by considering pricing strategies and tactics and will touch on patents and ownership of ideas. All of this material will be relevant in the final project of the course that begins on Monday, March 8. You will need to know all of this as you develop a new product to target a particular problem. In the final project, you and your group will brainstorm, select specifications, explore alternatives and design a consumer product. In the final project review you will need to present the technical information as you did for your midterm exam but in this final presentation you will also cover a marketing plan using all of the information learned in the marketing unit of the course. That final exam, presented to a review board, will be on Friday, May 5. Marketing Unit Specifics We will be covering one or two topics a week as detailed on the accompanying calendar. You will be responsible for reading the distributed material and contributing to the class by presenting a weekly topic(s). You should select two or three topics that will be covered. Students with common interests will be paired for presentations. You and your group will have two days to present the information. The balance of the week will be available for open discussion and the completion of the weekly assignment. Your group will be responsible for teaching the topic to the class. You should plan for approximately 1.5 hours of class time to cover your topic. I expect that we will have 5 presentation groups. There will be three groups of three students and two groups of four students. Your presentation will account for 25% of your six weeks grade (4th grading period). In addition there will be a total of 12 assignments to be handed in. Specific assignments are noted on the calendar and will be due at the end of each week. The first two will be on the third grading period and the other 10 will comprise the remainder of your 4th six weeks grade. Those assignments will be group work.
