Gateway to Technology Millennial Tech Middle School Veronica Martin 7th Grade Standards Standards for Technological Literacy Standard 11:Students will develop abilities to apply the design process. BM E:The process of designing involves presenting some possible solutions in visual form and then selecting the best solution from many. BM J:Make two-dimensional and three-dimensional representations of the designed solution. Standard 12:Students will develop the abilities to use and maintain technological products and systems. BM J:Use computers and calculators in various applications. Purpose Identify basic geometric relationships of shapes and solids. Use coordinate system to express geometric relationships. Create a three-dimensional (3D) model of an object. Demonstrate the ability to produce various documentation drawings from a 3D model. Produce the annotations to document various drawings made from a 3D model. Interpret the relationship of orthographic and auxiliary views to their parent 3D model. Summary Students learn how to transfer a simple hand sketch to communicate some aspect of a problem by creating a three- dimensional model on a computer. Students study basic geometrical shapes, such as ellipses, cones, cubes and spheres, and how they are combined to form complex geometry using the aid of the computer. The basic techniques that students will learn may be applied to making a model of a human body for medical purposes, creating a soft drink container, or manufacturing a starter motor for an automobile. Students build on drafting basics by adding many essential features to their 3D models and will learn to document, edit, and archive drawings as well as study techniques of adding features such as holes, slots, and chamfers. Finally, students will see that once they have created a 3D model of an object, the computer can show them the model from virtually a limitless number of viewpoints, greatly enhancing their visualization of the object as well as being a wonderful tool for multimedia presentations.
