Reverse Engineering

  2. 2. Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] Have you ever wondered how something worked, and so you took it apart? Well that in nutshell is called reverse engineering. Reverse Engineering has become a major and powerful tool in the engineering community. It is not only practiced but done on a daily basis with complains around the world. Reverse engineering is the process of taking something apart to see how someone else engineering (made) it. This breaks no patients or laws as long as you don’t duplicate the item. And It’s a great tool to build and develop brainstorming, and provide a wealth of knowledge for the investigating engineers. It push's competitors to be changing and improving there products at all times. And in my option, one of the most powerful tools out there. How is item constructed and why done this way?

  6. 6. Student Page Title Introduction Task Process Evaluation Conclusion Credits [ Teacher Page ] You have now successfully done the process know as reverse engineering. You took something that you didn’t understand, broke it down, and found out how someone else engineered it. With this tool there is no limit to your knowledge , and no traditional schooling required. People go to universities for years to learn how to do, what you just did. Congratulations, now I challenge you to go out and find something you don’t understand reverse engineer it. There will be extra credit given for any student who does another reverse engineering project. Contact me if interested.

  9. 9. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This project originated from a professor I had at Colorado State University in one of my mechanical engineering design classes. It is of coarse tuned down for simplicity of high school students. Keep in mind you can make it more complex or even more simple for younger kids. What I'm trying to do here is get away from just reports and essays, and get the kids to be more hands on showing that there is a ton of knowledge out there beyond books. It also covers topics from writing reports, giving speeches, and physics. Evaluation Teacher Script Conclusion
  10. 10. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page This content can span over a huge amount of subjects, from physic class to sciences and of coarse engineering classes. I would keep the age range from junior high and up, just because some of Newton’s ideas and things described are complex but the material can be decreased to elementary level or up to college level. I wrote it for a 10 th , 11 th level class. If not altered, The students should have a basic understanding of English, essay writing, speech, and physics. Newton's ideas and how forces work. All very basic. A couple class sessions prior to being assigned is all you would need to prep the class for the assignment. Evaluation Teacher Script Conclusion
  11. 11. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page I tried to integrate the Colorado model Content standards for 9 th thru 12 th grade science which you can view at there website. Colorado Science Standards (1 through 5) More specifically in each category: 1 st category (ask questions and state hypotheses using prior scientific knowledge to help design and guide development and implementation of a scientific Investigation) 2 nd category (Newton’s Three Laws of Motion explain the relationship between the forces acting on an object, the object’s mass, and changes in its motion) 3 rd category (there is a cycling of matter ( for example: carbon, nitrogen) and the movement and change of energy through the ecosystem (for example: some energy dissipates as heat as it is transferred through a food) 5 st category (there are cause-effect relationships within systems) I’m trying to get the students to think outside the normal teaching area, of books, memorizing, reading. I want them to spark an interest in an everyday items and want to understand them. And then of coarse quiz them to make sure there learning, and present there knowledge to the class. Which I believe is powerful! Kids teaching kids. Evaluation Teacher Script Conclusion

Nothing to complicated, just Newton's laws and force diagrams. I would prep the class with this information, about one or two class periods worth. What Newton's laws are and what kind of force diagrams you want. How to pick good machines that can be disassembled. For picking groups, I would let them be with there friends, trying to make this a fun project. But do as you want. I personally am a Mechanical engineering so I’m having fellow engineers come in to watch and ask questions, I think new faces makes it feel like more of a speech environment. And if there presenting to people in industry puts pressure to perform.
  13. 13. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page Material wise, the students are going to need to be able to find and disassemble a simple machine. So the students are going to need access to tools. I’m assuming they have tools at home, if not you as the teacher is going to need to provide a primitive set of tools for the group. I cant imagine many groups won’t have someone in it who as some basic tools. -No software needed or hardware. -No email system needed, but would help (maybe implement check ups) -There are websites listed on the students pages, but there just for more info and a little guidance, not essential Human resources: This can be taught with one teacher. Its mostly hands on time among the kids with the project, except for the few days before being assigned you should lay down some basic material knowledge (like explained before). I also have outside people coming in to watch the speeches. (like explained before) Evaluation Teacher Script Conclusion
  14. 14. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page I think I will get the most feed back of how much they learned after there speeches, there enthusiasm and how well they can answer my questions. The report is not my person main concern (you could put more weight on it) what I want to see them doing is taking a problem, using logic and critical thinking, and working towards an elegant explanation. The force diagram and report is too just help guide them. This project has also been centered around the Colorado Science Standards, as mentioned before, so a strong correlation using the scientific method which is tightly related to logical and critically thinking process. Mostly above all, I’m trying to spark a curiosity about the world around them, getting them involved hands on, and having fun in school. Evaluation Teacher Script Conclusion
  15. 15. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page Pre Assigned: Teach the basics of Newton's laws, and Force diagrams and maybe a pre intro. Day One: Intro to project. Set them in groups (make sure they understand what a simple machine is (ex: stapler) Let groups think about it, and give you a list of the machines they have picked. (can switch by next class period) Day Two: Let them get into there groups and help them take apart there machines, stressing that there trying to understand there machine, so work slow and take notes. (note bags for loss parts, must be able to reassemble) Day Three: Check to see where every one is… See if there understanding how Newton's laws effect there part, how forced effect there part ext… Continue disassembly and make sure report outline is being started. Day Four: Wrap up project, outline done and reassemble part Day Five: Reports Due, Speeches Due. Evaluation Teacher Script Conclusion
  16. 16. [ Student Page ] Title Introduction Learners Standards Process Resources Credits Teacher Page The kids now have true hands on experienced with a tool that is used everyday in the world, epically in engineering. It helped them to take a problem, analyze it and learn something entirely in depended from us. They then took that knowledge and taught other student. They wrote reports showing what they learned and gave drawing (force diagrams) on how physics (math) works in everyday life. Encourage your students to go out and find something that interreges them and investigate, take it apart, reverse engineer it and always, always ask questions??? .
