In this unit, students will learn and apply an engineering design process to collaboratively design a carnival game. As part of the design process, they will practice the art of brainstorming and begin to develop skills in graphically representing ideas through concept sketching. They will develop and test a solution and improve the design through iteration. In addition, they will apply statistical techniques to evaluate design solutions and apply those techniques to inform design decisions related to your game design.  They will use isometric and orthographic technical sketching as a means to model and communicate ideas, designs, and problem solutions. Students will develop basic 3D solid models of simple designs and produce technical drawings using CAD.  Students will learn the importance of precision measurement. They will use dial calipers to make precise measurements as they come to understand the concepts of precision and accuracy and their implication on engineering design and manufacturing. Students will apply statistics to quantify the precision and accuracy of measurements and of measuring tools.  Students will individually apply the design process and the skills and knowledge gained in this unit to evaluate and improve the design of a consumer product to meet stakeholder needs. Students will learn effective presentation techniques and present their solutions to an audience.
