Lesson 2: This lesson is to focus on design and modeling. The students will work in groups developing a set of drawings for their design of the metal testing machine, which they will make in proceeding lessons. This will include model making and CAD work.
This phase of the project is geared for the students to develop solid design principles. The lesson will focus on thinking through the process by sketching, writing technical specs, modeling and finally developing complete working drawings. This tends to be the hardest part for students since they just want to go out and build the machine as it develops. It is the goal of this lesson to show them that they need to do planning before building.
All lessons in this project assumes that the students and teacher will have had training and experience in the shop environment. Since the lesson is designed for CTE engineering, agricultural or welding students they should have been learning these skills throughout the year. It is assumed that the students would have been trained in some form of CAD or board drafting.
Science teachers can also have their students do the project but it is important that they work with their school's shop teacher and teach the proper safety and skills that will be needed to work in a shop environment.
