Course Description:

Design and Modeling (DM) provides students opportunities to apply the design process to creatively solve problems. Students are introduced to the unit problem in the first activity and are asked to make connections to the problem throughout the lessons in the unit. Students learn and utilize methods for communicating design ideas through sketches, solid models, and mathematical models. Students will understand how models can be simulated to represent an authentic situation and generate data for further analysis and observations. Students work in teams to identify design requirements, research the topic, and engage stakeholders. Teams design a catapult, fabricate and test it, and make necessary modifications to optimize the design solution. 

Lesson 1 Introduction to Design

In Lesson 1 students are given an instant design challenge that leads them to the exploration of the engineering design process. They learn thumbnail, orthographic, isometric, and perspective sketching as methods for communicating design ideas effectively without the use of technology. The use of a common measurement system is essential for communicating and fabricating designs. Students learn conversions between two measurement systems and apply measurement skills while dimensioning sketches. Students conduct a mechanical dissection in the lesson project to better understand how objects and parts interact while using sketches to communicate and document their findings.

Lesson 2 Modeling and Statistical Analysis

In Lesson 2 students transfer a two-dimensional representation to a three-dimensional solid model using technology (Tinkercad). Students study basic geometric shapes within a mathematical model and use combinations of geometric primitives to form more complex shapes. During the design project, students apply the design process to create a puzzle cube. Students create a solid model using a computer-aided design (CAD) application and fabricate their design solution for testing. Students use spreadsheet software to complete statistical analysis from their testing results to determine whether their design meets the criteria and constraints.

Lesson 3 Design Challenge

In Lesson 3 students will complete a design challenge.
